A 27-year-old female presents with left knee pain after a low-speed motor vehicle collision in which her knee hit the dashboard. She is tender over the patella without significant effusion and has an intact extensor mechanism. The above x-ray was obtained (Image 1. X-ray left knee. Case courtesy of Dr. M. Mourits, Radiopaedia.org, rID: 14476).
A 64-year-old female presented to the emergency department (ED) in cardiac arrest. Her family members heard her fall in the bathroom and started CPR. EMS intubated the patient and 20 minutes of CPR was done en route. Return of spontaneous circulation (ROSC) was achieved after fifteen minutes of resuscitation in the ED.
At baseline, the patient ambulated with her walker and was conversant. She was having abdominal pain and nausea for the past three days after recently being diagnosed with a urinary tract infection. On arrival to the ED, the patient was pulseless with ventricular fibrillation. The patient received ten doses of epinephrine, two doses of sodium bicarbonate, calcium, amiodarone, magnesium, and one dose of naloxone during the resuscitation. One defibrillatory shock was administered. She was started on a norepinephrine drip and an amiodarone drip.
Computed tomography (CT) of the head was negative. CT of the chest was significant for left pneumothorax and left-sided subcutaneous emphysema. A pigtail chest tube was placed. After a few hours, she developed worsening abdominal distension. An abdominal CT scan revealed the images shown.
