A Case Report Evaluating Gastric Emphysema versus Emphysematous Gastritis
DOI: https://doi.org/10.21980/J8ZH26A 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.
Telescoping into Adulthood: A Case Report of Intussusception in an Adult Patient
DOI: https://doi.org/10.21980/J8Q06CComputed 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.
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).
