CSpine Fracture CT Axial Unannotated. JETem 2025

A Case Report of an Unstable C-spine Fracture in the Emergency Department

Jinho Jung, BS*, Tyler Rigdon, MD^, Alisa Wray, MD, MAEd^ and Danielle Matonis, MD^

DOI: https://doi.org/10.21980/J8SK90 Issue 10:2 No ratings yet.
The initial workup in the ED showed an acute displaced fracture of the left occipital condyle (CT-coronal, fracture of the left occipital condyle, red arrow; displacement, orange line), a shattered left lateral mass with involvement of the vertebral canal (CT-axial, red arrow), and malalignment of the craniocervical junction (CT-sagittal, red outline). The CT angiogram head and neck showed a possible irregularity in the left vertebral artery. The CT head without contrast had no significant findings.

Hydropic Gallbladder. CT Coronal Unannotatd. JETem 2025

A Case Report of Hydropic Gallbladder Presenting as Right Lower Quadrant Abdominal Pain

Savannah Tan, MD*, Zoe Adams, BA^, Scott Rudkin, MD, MBA* and Danielle Matonis, MD*

DOI: https://doi.org/10.21980/J8DD26 Issue 10:2 No ratings yet.
Computed tomography (CT) of the abdomen and pelvis with contrast was ordered, and general surgery was consulted for the initial working diagnosis of acute appendicitis. However, the CT scan resulted with findings of a markedly distended gallbladder measuring approximately 14.5 x 4 centimeters (cm) with marked gallbladder wall thickening (magenta) and pericholecystic fat stranding (cyan). The appendix was not dilated and had no inflammatory changes or edema. Follow-up right upper quadrant ultrasound confirmed the diagnosis of acute cholecystitis.

Wolff A et al. Right atrial thrombosis. Parasternal long US 3 annotated

A Case Report of Right Atrial Thrombosis Complicated by Multiple Pulmonary Emboli: POCUS For the Win!

Andrea Wolff, MD*, Evan Leibner, MD* and Jill Gualdoni, MD^

DOI: https://doi.org/10.21980/J8TM07 Issue 10:1 No ratings yet.
Pulmonary POCUS was performed by the ED physician (GE Venue, C1-5-RS 5MHz curvilinear transducer), and lung examination was unremarkable with no pleural effusion, pneumothorax, or infiltrate. Subxiphoid views (GE Venue, 3Sc-RS 4MHz phased-array transducer) were obtained because this patient’s COPD with severe pulmonary hyperexpansion made parasternal and apical 4-chamber views suboptimal. A large thrombus can be seen within the right atrium (movie 1, images 1, 2). This has a serpiginous, rounded appearance and is mobile, appearing to swirl within the right atrium with intermittent extrusion through the tricuspid valve. A pacemaker wire is also visible within the right ventricle as a non-moving, hyperechoic, linear structure with posterior enhancement artifact. Pericardial effusion is not present.

Retropharyngeal Abscess in an Adult Patient Presenting with Neck Fullness and Dysphagia: A Case Report

Justin Rederer, DO*, Tanner Folster, DO^ and Sara Dimeo, MD, MEHP^

DOI: https://doi.org/10.21980/J8M36G Issue 10:1 No ratings yet.
Contrast-enhanced CT soft tissue of the neck showed evidence of a prevertebral/retropharyngeal fluid collection, extending from the odontoid tip to the inferior C4 vertebral body margin, measuring 5.4 x 1.0 x 3.3 centimeters (cm) in size (yellow lines) without gross airway narrowing.

A Man With Chest Pain After An Assault – A Case Report

DOI: https://doi.org/10.21980/J8J93S Issue 9:3 No ratings yet.
On exam, we found a suspected chest wall abscess with surrounding erythema (blue arrow). The patient underwent CT of the chest which showed a comminuted displaced midsternal fracture (yellow arrow) with moderate fluid and air anteriorly (red arrow), consistent with an abscess. His laboratory results had no significant abnormalities.

Gastric Emphysema. Coronal CT annotated. JETem 2024

A Case Report Evaluating Gastric Emphysema versus Emphysematous Gastritis

DOI: https://doi.org/10.21980/J8ZH26Issue 9:2 No ratings yet.
A CT scan of the abdomen and pelvis was obtained and revealed gas within the gastric wall at the fundus (blue arrows), concerning for gastric emphysema versus emphysematous gastritis. There was no gastric wall thickening, free air, bowel obstruction, drainable fluid collection, or evidence of portal venous gas. Incidentally, hepatomegaly and likely hepatic steatosis were also noted.

Adult Intussusception. CT Axial Unannotated. JETem 2024

Telescoping into Adulthood: A Case Report of Intussusception in an Adult Patient

Neena Joy, DO*, and Laura Kolster, DO*

DOI: https://doi.org/10.21980/J8Q06C Issue 9:2 No ratings yet.
Computed tomography imaging of the abdomen and pelvis with intravenous and oral contrasts was obtained. In the axial view, one will see a concentric ring formed by layers of bowel, mesenteric vessels, and fat (red arrow and circle); this is the equivalent of the ultrasonographic “target sign.” The inner ring (blue arrow) represents the lead point causing telescoping of the bowel. One can see that the proximal bowel is dilated (yellow arrow). In the coronal view, one can see an obstructive mass, also known as the lead point (red arrow), located in the lumen of the descending colon. Located proximal to the lead point are dilated loops of bowel with edematous changes and fat stranding (pink circle). The proximal portion of the bowel will take on a concentric appearance with the telescoping loop of bowel.

Upon arrival at the trauma center, a FAST revealed a large, well-circumscribed abnormality (red outline) deep to the liver (blue outline and star) and gallbladder (green outline and star). The right kidney and hepatorenal space were not clearly visualized. The remainder of the FAST showed no free fluid in the splenorenal space, pelvis, and no pericardial effusion. He had lung sliding bilaterally.

A Patient with Generalized Weakness – A Case Report

The CT of the abdomen and pelvis showed evidence of a large subcapsular rim-enhancing fluid collection with multiple gas and air-fluid levels along the right kidney measuring 8 x 4 cm axially and 11 cm craniocaudally (blue outline) with mass effect on the right renal parenchyma (yellow outline). Another suspected fluid collection adjacent to the upper pole of the right kidney measuring 4 x 3.4 cm was noted (red outline). Bilateral pyelonephritis was suggested without hydronephrosis or nephrolithiasis. The findings suggested complicated pyelonephritis with emphysematous abscess and hematoma formation.

Case Report of Herpes Zoster Ophthalmicus with Concurrent Parotitis

Serena Tally, BS*, Michelle Brown, DO* and Edmund Hsu, MD*

DOI: https://doi.org/10.21980/J8R93N Issue 8:2 No ratings yet.
The presence of soft tissue stranding about the parotid gland suggested an underlying inflammatory or infectious process of the parotid gland. Cellulitis was considered as a possible diagnosis as well, given the presence of soft tissue stranding in the dermis that is adjacent to the parotid gland. Fortunately, no enhancement was seen in local muscles, fascia, or bones to suggest a myositis, fasciitis, or osteomyelitis. By using the anatomy of the patient and understanding the changes that occur on CT when inflammation is present, the appropriate depth and location of infection can be made, allowing for appropriate treatment regimens.
