Pulmonary Embolism: Diagnosis by Computerized Tomography without Intravenous Contrast

James Roy Waymack, MD*

DOI: https://doi.org/10.21980/J8001ZIssue 2:1[mrp_rating_result]
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.

Intraocular Foreign Body: Ultrasound and CT Findings

Maja Feldman, MPP*, Kristi Shigyo, MD^ and Amy Kaji, MD^

DOI: https://doi.org/10.21980/J8JS3MIssue 2:1[mrp_rating_result]
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.

Intracranial Hemorrhage Following a 3-week Headache

John Jiao, MHS* and Alisa Wray, MD*

DOI: https://doi.org/10.21980/J89885 Issue 2:1[mrp_rating_result]
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

Christopher Gilani* and Shannon Toohey, MD, MA*

DOI: https://doi.org/10.21980/J8PP46 Issue 1:2[mrp_rating_result]
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).

Femoral Neck Fracture

Jonathan Lee* and Shannon Toohey, MD, MA*

DOI: https://doi.org/10.21980/J89G6GIssue 1:2[mrp_rating_result]
In the anteroposterior view bilateral hip x-ray, there is an evident loss of Shenton’s line on the left when compared to the normal right, indicative of a fracture in the left femoral neck. This correlates with findings seen on pelvic CT, which reveals both a subcapital fracture and transcervical fracture. The neck of the femur is displaced superiorly relative to the head of the femur while the head of the femur remains in its anatomical position within the acetabulum.
