Trauma by Couch: A Case Report of a Massive Traumatic Retroperitoneal Hematoma
DOI: https://doi.org/10.21980/J84D2QUpon 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
DOI: https://doi.org/10.21980/J8593CThe 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
DOI: https://doi.org/10.21980/J8R93NThe 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.
Imaging Findings of Small Bowel – Diverticulitis: A Case Report
DOI: https://doi.org/10.21980/J8F078Bedside ultrasound was performed and showed thickened bowel wall (orange marker), fat enhancement (green marker), and phlegmonous structure with central echogenicity (yellow marker). Imaging of the abdomen and pelvis with CT showed marked wall thickening and inflammatory change involving a 7.0cm segment of the distal/terminal ileum suspicious for severe ileitis with phlegmon and microabscess on the coronal image (yellow arrow). Additonally, the transverse images show a small rim-enhancing focus within this region of inflammation measuring up to 1.4cm which could represent microabscess (yellow arrow). Diagnosis of diverticulitis by ultrasound is made by identifying the following findings: colon wall thicker than 5mm, fat enhancement, evidence of abscess, visualized diverticuli, air artifacts suggesting diverticuli, and tenderness with compression of the probe.6 Diagnosis of diverticulitis by CT is made by identifying the following findings: colonic wall thickening, pericolic fat stranding, abscess formation and enhancement of the colonic wall. Often, these signs are associated with an identifiable inflamed diverticulum.7
Epilepsy Caused by Neurocysticercosis: A Case Report
DOI: https://doi.org/10.21980/J81P96In our patient, two lesions were most notable on CT in the frontal and occipital lobes. The lesion in the left frontal lobe (blue circle) was an approximately 1.5 centimeter (cm) rounded area with rim enhancement and surrounding hypodensity, consistent with vasogenic edema. A similar sized low-density area in the left occipital lobe (red circle) was noted, with increased peripheral density at the 3 o’clock position representing calcification. There were no areas of apparent hemorrhage or midline shift. The final radiology report concluded there were multiple cystic lesions, one with surrounding vasogenic edema in the left frontal lobe.
A Case of Community-Acquired Tuberculosis in an Infant Presenting with Pneumonia Refractory to Antibiotic Therapy
DOI: https://doi.org/10.21980/J8X07MChest radiographs during the initial presentation at seven weeks of life demonstrated right lower lobe (RLL) air space opacity on both PA and lateral views, compatible with pneumonia (referenced by yellow and green arrows, respectively). Repeat chest radiograph performed 12 days after the initial imaging revealed persistent right lower lobe opacity and right hilar fullness, seen as an opacified projection off of the mediastinal border as compared with the prior image, concerning for lymphadenopathy (designated by the aqua arrow). On the third presentation, computed tomography (CT) of the chest with intravenous contrast found persistent right lower lobe consolidation, innumerable 2-3 mm nodules, and surrounding ground glass opacities. This is best visualized as scattered areas of hyperdensity in the lung parenchyma. Axial images confirmed the presence of right hilar as well as subcarinal lymphadenopathy (indicated by white and pink arrows, respectively). Magnetic resonance imaging (MRI) of the brain with IV contrast was performed which showed a punctate focus of enhancement in the left precentral sulcus compatible with a tuberculoma (denoted with red arrow).
Electronic Cigarette or Vaping-Associated Lung Injury Case Report
DOI: https://doi.org/10.21980/J8S65PThe CT of the chest with contrast showed subcutaneous emphysema (green star), pneumomediastinum (yellow arrow), and pneumopericardium (purple asterix) without an identifiable tracheal tear. Extensive air was visualized as hypodense areas within the chest wall within the soft tissue. The image also detailed a hypodense area surrounding the heart consistent with pneumopericardium. No disruption of the trachea was present. Additionally, the CT of the chest also showed bilateral ground glass airspace opacities (red stars) with subpleural sparing that is consistent with EVALI findings.2,5 These specific findings have been seen in many of the EVALI cases.5 This image is interesting because there is extensive pneumomediastinum with no clearly identifiable cause. The imaging shows no esophageal or tracheal or lung injury, so it is important to note relevant information collected during interview regarding patient’s recent history of vaping THC, especially when establishing a differential diagnosis.
A Case Report of a Man with Burning Arm and Leg Weakness
DOI: https://doi.org/10.21980/J8V659A non-contrast computed tomography (CT) of the head and neck was performed, followed by an MRI of the cervical spine. The CT demonstrated congenital narrowing of the cervical spinal canal, with posterior disc osteophyte complex and disc bulge at C3-4 and C4-5 (arrow). The T2-weighted MRI additionally demonstrated obliteration of the anterior and posterior subarachnoid space at the level of C3-C5, with associated patchy central cord signal abnormality (arrow).
Thigh Mass Case Report
DOI: https://doi.org/10.21980/J8QD3CPoint-of-care ultrasound (POCUS) demonstrates a large, subcutaneous mass with areas of mixed echogenicity. The mass contains fluid-filled, anechoic areas with internal septations and absent doppler flow. The majority of the mass appears isoechoic to the surrounding tissues with a hyperechoic border. Computed tomography (CT) of his right thigh shows a 16 x 8.1 x 9.5 cm heterogenous, complex mass within his hamstring muscles, inferior to the femur. His lab work was significant for a white blood cell (WBC) of 17.3 (103/µL).
A Case Report of May-Thurner Syndrome Identified on Abdominal Ultrasound
DOI: https://doi.org/10.21980/J8C64KThe patient initially received a venous doppler ultrasound that showed no evidence of a right or left femoropopliteal venous thrombus. Due to the high suspicion of a DVT given the symmetric swelling to the entire limb and acute onset of pain, a CTV was ordered. The transverse view of the CTV showed chronic thrombotic occlusion of the proximal left common iliac vein associated with compression from the right common iliac artery (figure 1, transverse image of CTA), as well as thrombotic occlusion of the left internal iliac vein tributary and corresponding left ascending lumbar vein. Given the previously mentioned clinical context, these features suggested the diagnosis of May-Thurner syndrome.
