The computed tomography (CT) of the abdomen and pelvis revealed significant subcutaneous gas tracking along the perineum and right gluteal region (orange outline) into the scrotum with associated scrotal edema (yellow arrow) and subcutaneous inflammatory fat stranding of 0.92 cm (red arrow) consistent with Fournier’s gangrene. There is early fluid loculation along the right medial gluteal cleft of 5.85 cm (green arrow) without a sizeable drainable abscess seen.
Computed tomography (CT) sinus with contrast demonstrated complete opacification of left paranasal sinuses and nasal cavity, and a linear radiopacity within the left maxillary sinus consistent with a foreign body. There were additional left facial subcutaneous radiopaque opacities.
The patient’s abdominal ultrasound revealed intussusception in the right upper abdominal quadrant. The transverse ultrasound view showed a “doughnut sign” (dashed yellow line), telescoping bowel (yellow arrow), and invaginated hyperechoic mesenteric fat with crescent configuration (dashed orange line). The sagittal ultrasound view demonstrated the intussusception formed by the outer recipient bowel loop (yellow arrows), invaginated hyperechoic mesenteric fat (orange asterisks), and telescoping bowel centrally (red arrow).
On exam, the patient has a gross deformity to the left pinna that was not painful to touch or fluctuant. Findings and history are consistent with cauliflower ear, secondary to a chronic auricular hematoma.
The computed tomography (CT) scan demonstrates prominent enlargement and heterogeneous enhancement of the right submandibular gland (single large arrow) compatible with sialadenitis. There is no evidence of a sialolith or obstruction on the CT. There is associated edema (two small arrows) of the right submandibular space, parapharyngeal space and anterior right neck with partial effacement of the right vallecula and right pyriform sinus.
An electrocardiogram (ECG) was concerning for ST segment elevation in leads II, III, aVF, and V4, with subtle ST elevations in V5 and V6 (see black arrows). There is also ST segment depression in aVL (see blue arrows).
The ultrasound video clip demonstrates a transverse view of the pelvis using the endocavitary probe. The bladder can be seen on the anterior portion of the scan (yellow arrow), while the uterus with an intrauterine pregnancy is visible posteriorly (blue arrow). The thickened appearance of the uterine wall is also indicative of pregnancy. A large, anechoic cystic structure measuring approximately 5 cm is seen in the vicinity of the patient’s left adnexa (pink arrow), which raises concerns for ovarian torsion.
Plain film anteroposterior (AP) radiography of the chest shows left-sided subcutaneous emphysema (red arrow) with overlapping muscle striations of the pectoralis major (green arrow). After chest tube placement (blue arrow), AP chest radiography shows persistent left-sided subcutaneous emphysema (red arrow). CT of the chest shows pneumomediastinum (blue arrow), left apical pneumothorax (pink arrow), and subcutaneous emphysema (red arrow) at the level of T2. At the level of T6, rib fractures can be visualized on the CT (yellow arrow). At the level of T8, left sided pneumothorax is also seen (pink arrow) as the absence of lung tissue on CT.
The patient’schest X-ray revealed a prominent mediastinum and opacification in the left middle and lower lung fields. The CT showed an aortic aneurysm extending from the thorax to the abdomen with rupture near T7 (blue arrow). It also showed periaortic hemorrhage with active extravasation (green arrow) likely secondary to a penetrating ulcer and bilateral pulmonary opacities concerning for hemothorax (pink arrow).
