A large chest wound was clinically obvious. A chest radiograph performed after intubation showed subcutaneous emphysema, an anterior rib fracture, and a right-sided pneumothorax. He was then taken to the operating room for further management.

A non-contrast computed tomography (CT) scan showed a hyperdensity along the right middle cerebral artery (MCA) consistent with acute thrombus. The red arrow highlights the hyperdensity in the annotated image.

CT angiogram showed multiple large acute pulmonary emboli, most significantly in the distal right main pulmonary artery (image 1 and 2). Additional pulmonary emboli were noted in the bilateral lobar, segmental, and subsegmental levels of all lobes. There was a peripheral, wedge-shaped consolidation surrounded by groundglass changes in the posterolateral basal right lower lobe that was consistent with a small lung infarction (image 3).

Non-contrast CT of the chest demonstrates hyper-densities within both central and sub-segmental pulmonary arteries bilaterally (see yellow arrows). The right ventricle is dilated.

An immediate post-op abdominal x-ray performed after the patient’s VP shunt revision 30 days prior to this ED visit reveals the VP shunt tip in the mid abdomen. A CT of the abdomen performed on the day of the ED visit reveals the VP shunt tip interposed between the spleen and the diaphragm.

Point of care ultrasound revealed a mobile, radiolucent hyperechoic structure (see red arrow) with reverberation within the posterior chamber (see blue arrow), likely a metallic foreign body. Linear areas of mobile hyperechoic material revealed possible vitreous hemorrhage (see purple circular area). Orbital non-contrast CT confirmed a 3 mm metallic focus within the dependent portion of the left globe, lodged in the posterior sclera, with some vitreous hemorrhage but no evidence of globe rupture. Ophthalmology was consulted and the patient was taken to surgery later that night.

The patient’s head CT showed a significant area of hyperdensity consistent with an intracranial hemorrhage located within the left frontal parietal lobe (red arrow). Additionally, there is rightward midline shift up to 1.1cm (green arrow) and entrapment of the right lateral ventricle (blue arrow).

Gastric Bezoar

In the abdominal radiograph, a nonspecific and non-obstructive bowel gas pattern with no air-fluid level was noted, however the stomach was distended with soft tissue. The CT abdomen/pelvis revealed a distended stomach with undigested heterogeneous contents (presumed bezoar).

Trimalleolar Fracture

DOI: https://doi.org/10.21980/J8PP46 Issue 1:2 No ratings yet.

Anteroposterior (AP), lateral, and oblique x-ray views were obtained. The AP view revealed a displaced spiral fracture of the lateral malleolus (red) and a vertical fracture of the medial malleolus (blue). The lateral view revealed a displaced fracture of the posterior malleolus, tibial plafond (yellow), and the oblique view showed widening of the distal tibiofibular syndesmosis (green). CT scans confirmed trimalleolar fracture, annotated with the same colored lines (red, lateral malleolus; blue, medial malleolus; yellow, posterior malleolus).
