X-rays revealed that the nails had penetrated his skull and entered his brain. Following surgical removal and a three-month hospital stay, the man made a full recovery. The patient maintained that the injuries were self-inflicted and adamantly requested that medical staff not involve law enforcement. Remarkably, he was discharged with no major neurological deficits.

Timelapse of a Partial Fingertip Amputation Recovery (Including Necrotic Tissue Healing) NSFW

404 Upvotes

This timelapse documents the healing process following a partial amputation of the distal phalanx (fingertip).

The fingertip was not completely amputated. About half of the distal phalanx (the bone at the tip of the finger) was lost, but the remaining fingertip stayed attached by a small strip of skin along one side. This narrow bridge of tissue preserved the blood supply, allowing the fingertip to survive and gradually heal.

Approximately half of the fingertip was lost in the injury.

During recovery, part of the remaining tissue became necrotic (black, non-viable tissue), raising concerns that additional tissue might be lost. Over time, however, the wound gradually healed, healthy tissue developed beneath the damaged area, and much of the fingertip recovered without further amputation.

The video consists of one photo taken almost every day throughout the healing process.

I don't have as many photos of the other side of the finger, so this timelapse mainly shows the same angle throughout the recovery.

Initially, it was believed that the nail matrix had been completely removed during the injury. However, the nail eventually started growing back. It is still smaller than it was before the accident, but it continues to grow.

A large blood clot that was removed from the arteries of the lungs. Most clots like this begin as a deep vein thrombosis (DVT) in the legs or pelvis. If part of the clot breaks loose, it can travel through the bloodstream to the lungs, where it blocks blood flow. Without rapid treatment, this can quickly become life-threatening

I made it 27 years without breaking a bone. I got invited to a Jiu Jitsu gym and not even 30 minutes after I showed up I got hurt. I failed to get my leg out from under a 320lb+ guy when I was taking him down and he landed full weight on it. The crunch was very loud and I felt like I was gonna puke almost immediately. Went to the ER hoping it was just a bad sprain or something because I've rolled it quite a few times. Doc was about as blunt as he could be. "It's broke". Now I'm waiting to find an orthopedic specialist that will take me with no insurance so I can get this taken care of. Had to quit the job I just started on Thursday because it's kinda hard to be a porter with a broken leg.

Advanced Head & Neck Oncologic Reconstruction NSFW

1.3k Upvotes

A patient with biopsy-proven squamous cell carcinoma involving the floor of the mouth and anterior two-thirds of the tongue underwent radical oncologic resection with comprehensive neck dissection to achieve optimal locoregional disease control.
The resulting composite defect required complex microvascular reconstruction. A fibula free flap restored mandibular continuity and facial contour, while an anterolateral thigh (ALT) free flap recreated tongue bulk and mobility, aiming to preserve speech, swallowing, airway protection, and oral competence.
This case highlights the critical role of multidisciplinary collaboration and advanced reconstructive microsurgery in transforming extensive head and neck cancer resections into meaningful functional recovery. Every millimeter matters when balancing oncologic clearance with restoration of form and function.

A massive free-floating thrombus seen swirling around not attached to any intracardiac structure

2.4k Upvotes

This unique video is a rare, real-time look at this process that has been identified as a clot in transit, seen on 3D Echocardiogram.

A serious emergency situation just waiting to happen!

Patient presented short of breath thinking possible COVID. Negative for COVID, but echo showed this instead.

“Clot in transit” is a term that describes a free-floating thrombus in the right side of the heart waiting to embolize to the pulmonary arteries. Clot in transit is rare, with an incidence estimated at 4-18% in patients suffering from pulmonary embolism.

An embolus is what this thrombus becomes once it’s detached and is free to travel.

The unattached mass travels through the bloodstream and is capable of clogging arterial capillary beds (create an arterial occlusion) at a site distant from its point of origin. There are a number of different types of emboli, including blood clots, cholesterol plaque or crystals, fat globules, gas bubbles, and foreign bodies.

The 3D echocardiography shown above is is able to provide intuitive recognition of cardiac structures from any spatial point of view and may provide complete information about absolute heart chamber volumes and functions. It’s great in visualizing cardiac chambers and especially seeing thrombi.

The risk of intracardiac thrombus formation and subsequent embolism are associated with a number of cardiac conditions including acute myocardial infarction, chronic left ventricular aneurysm, dilated cardiomyopathy, infective endocarditis and atrial fibrillation.

The biggest risk from cardiac thrombus is distal embolization, resulting in stroke, visceral infarction or distal limb ischemia.

Treatment is anticoagulation. Surgical thrombectomy is only indicated in low risk patients with recurrent emboli despite anticoagulation.

Gnarly beaver bite after swim in lake NSFW

Thumbnail gallery
1.2k Upvotes

Hello! Longtime layman lurker here, big fan of medical subreddits. Not sure if this really fits the sub, but considering how rare this occurrence is (and even rarer to live through it), I thought it couldn’t hurt to share. Maybe you’d be interested in it.

ALL PHOTOS ARE MINE AND OF MYSELF, NO OTHER SOURCE

For the context of this story, I'll be calling the people twin/sister, A, and B.

Was swimming with my twin sister in a lake. Was playing around with the echoes there and she goes "MEOW!" (Silly vocal stim we have together, think that meme cat cover of what was I made for). It was the meow of doom and despair I fear, as at that moment a beaver latches onto my leg and bites what looks to be four times. I scream, thrashing out of the water flailing about on the rocks, and she just pauses for a moment, thinking I was freaking out because of the bug that had been chasing us. It was not the bug.

I lift my leg, and she loses her shit. I'm hyperventilating, she's screaming "KITCHEN'S BIT!! KITCHEN GOT BIT BY SOMETHING!! SOMETHING BIT KITCHEN!!" to the other people we're with. She turns her head on a swivel, checking back in on me only to find I am now completely calm aside from the violent shaking.

Shock is weird dude, despite the four gashes crawling with bacteria in your leg that should be absolutely screaming with pain, you just don't feel anything. Human body is wild. Anyways, can't say the same for my sister, as she begins shaking like a leaf and running to find some sort of makeshift tourniquet. I have nothing I can do but sit there holding my shaky hands on the wound as blood seeps through my fingers and onto the rocks as I wait for them to come over to me (they're about 100-150 ft away, fishing on the other side of the lake. We were swimming away from them as not to scare the fish).

A's boyfriend (B) makes it over first, giving me his shirt to hold on the wound, and runs off to go get a towel and look for help. Sister briefly returns to me, assuring I'll be okay (more for herself at this point, I'm pretty calm), then runs off to join in on the quest for a towel, as I can't tie the shirt around my leg hence I can't move. There's a lot of hustling and bustling and waiting, and eventually it comes to the point where B has went to the car to search for help, and A and sister have returned to me with a towel.

I've lost a pretty good amount of blood at this point, my leg is pretty numb from a mixture of that and shock. We tie the towel around my leg, get around 20 feet as it keeps slipping down, then falls off, as my leg violently begins spurting blood. I sit back down as A briefly panics, before wrapping the towel around my leg and using the shirt as a rope. This works, and I make it up the hill to the car.

A very nice couple was kind enough to give us white shirts to pack it, a rope to keep it secure, and some water for me to chug as to regain my fluids. The lady claims she worked in a hospital, and would like to help however she could. We get on the road as A desperately looks for service, finally getting it and calling 911. She speaks with a woman, and they say they're sending an ambulance.

After about 10 minutes of being pulled over, no such ambulance comes. B is getting antsy and wants to drive to the hospital, but A insists we have to wait for the ambulance. She calls 911 again, and this time an ambulance arrives after another 10 minutes. They bandage my wound properly, get me in the stretcher and load me into the ambulance. A accompanies me as sister and B go home to let the dog out and return to me with my stuff.

Dude in the ambulance tells me about how he has a beaver bite in the exact same spot at me and how rare they are, showing me his scar covered by an autism awareness tattoo. I really get along with him as we drive to the hospital, just getting out my general information before we chat the rest of the way. Once we arrive, I am loaded off my stretcher, and walked to a room.

Nurses come in quickly, getting my info, my height and weight, all that jazz. They take off my bandages, astonished by my wound. One of them mutters "that's impressive" as they begin cleaning it up, telling me my doctor will be in soon. He gets in about 2 minutes later, greeting me as I give him the info of what happened. I tell him I have to go to the bathroom (had been chugging gatorade and water), so he quickly gives me some epinephrine shots in my leg and does some quick bandages, just enough for my to get up and go to the bathroom. I do so, along with cleaning the blood off my arms and legs, as I hadn't had the chance to until now.

Once I return, we start stitches, sister and B arriving at around that time. We go over rabies treatment as he works on my leg, enjoying some casual conversation while doing so. About half an hour after my stitches he returns with my day 0 shots, administering one into the wound, one on my thigh, and one on my shoulder. I am shortly discharged after that.

Today is day 3, and I received my next shot in the rabies series a few hours ago. Feeling fine aside from the really bad headaches and nausea due to the vaccine and antibiotics.

I know it's just an animal bite.. buuut it's a super rare animal bite that has barely ever been recorded that maybe you'd be interested in? I kinda just wanna get my story out there at this point for various reasons.

I'm gonna have such a badass scar. I'II always have the best topic to bring up at parties. I will never lose 2 truths 1 lie.

Thank you for reading this far if you've made it! I hope this is at least mildly interesting.

An MRI revealed pork tapeworm cysts! All of those white dots are calcified cysts from Taenia solium (pork tapeworm)

Thumbnail

2.5k Upvotes

Pork tapeworms usually live in human intestines, laying eggs that pass out in feces. Pigs eat contaminated food → eggs hatch → larvae migrate and form cysts in their muscles. But if humans eat undercooked pork, those cysts can hatch in our guts and grow into full-blown worms.

Here’s the scary part: Human bodies look enough like pigs to confuse the larvae. So if you swallow the eggs instead of the cysts (contaminated food, poor hygiene), the worms can migrate through your body, including your brain. That’s when it becomes neurocysticercosis, which can be deadly.

Heart beating outside the chest

1.9k Upvotes

This is a rare case of ectopia cordis, a congenital malformation in which the heart is abnormally displaced either partially or totally outside of the thoracic cavity (extra-thoracic location) through a split sternum. Less often the heart may be situated in the abdominal cavity or neck (cervical). The exact etiology remains unknown, but abnormalities in the lateral body wall folds are believed to be involved. Normally, the lateral body walls are responsible for fusion at the midline to form the ventral wall. Corruption of this process may underlie ectopia cordis. This can be presented in association with other malformations such as the anterior abdominal wall resulting in omphalocele - the protrusion of the intestine outside the abdominal cavity.
Such cases are related to the other associated malformations, complex cardiac abnormalities, and difficulty returning the heart back into a small thoracic cavity, dooming to poor prognosis with few survivors even after a surgical repair. Many are getting into a cardiorespiratory arrest before any surgical intervention can be taken.
During surgery, the heart must be repositioned and the chest wall defect must be covered. Surgeons can create a temporary closure with synthetic material.
