Rapidly Progressive Painless Acute Aortic Dissection: A Case Report
DOI: https://doi.org/10.5070/M5.52348A POCUS of the abdomen at that time demonstrated findings concerning for a dissection flap in the abdominal aorta (green arrows), and a new mild to moderate pericardial effusion was seen on a repeat cardiac POCUS suggesting an evolving aortic dissection (blue arrows). The patient’s CTA revealed a type A AAD with extension from the aortic root to the bilateral external and internal iliac vessels as well as the coronary arteries (red arrows).
Computed Tomography Findings of Cerebral Venous Thrombosis: A Case Report
DOI: https://doi.org/10.5070/M5.52331The emergency physician ordered a non-contrast head CT and CT venogram of the head given worsening symptoms with disequilibrium and CVT risk factors of postpartum coagulopathy. The non-contrast head CT demonstrated a hyperdensity occlusion of the left transverse sinus (blue arrow). This serpiginous hyperdensity is called the “cord” or “string” sign, which is thrombosis within the vein. The CT venogram of the head demonstrated occlusion of the left transverse (red arrows) and sigmoid sinus (yellow arrow).
Hematoma, Hemarthrosis, and Hemotympanum: A Case Report of Acquired Hemophilia A
DOI: https://doi.org/10.5070/M5.52344Non-contrast computed tomography (CT) scan of the left knee confirmed a small to moderate suprapatellar joint effusion with Hounsfield unit measurements suggestive of blood products (+47 Hounsfield units), consistent with acute hemarthrosis. The hemarthrosis appears as a gray, fluid-density collection slightly darker than the surrounding tissues that conforms to the suprapatellar space anterior to the femur, continuing distally between the femur and the patella.
Blunt Cerebrovascular Injury: A Visual Case Report with Computed Tomography Angiography Findings Revealing Carotid and Vertebral Artery Dissection
DOI: https://doi.org/10.5070/M5.52229Computed tomography angiography of the neck showed worsening right ICA dissection with increased size of the pseudoaneurysm to 9 mm and worsening stenosis to greater than 70%. Computed tomography angiography of the neck also showed a new dissection of the V2 segment of the right vertebral artery with a 3 mm pseudoaneurysm and greater than 50% stenosis.
A-Lines below the Diaphragm – A Case Report of Occult Pneumoperitoneum
DOI: https://doi.org/10.5070/M5.52389The RUQ POCUS focusing over the left liver lobe shows multiple enhanced peritoneal stripe signs (red arrows) and several reverberation artifacts (yellow arrows). The second RUQ POCUS of the right lobe of the liver and the gallbladder shows reverberation artifacts (yellow arrow) and ring-down artifacts (blue arrow). The chest X-ray shows free air under the right diaphragm (orange arrow), which indicates pneumoperitoneum. The CT abdomen and pelvis show pneumoperitoneum near the porta hepatis (green arrow).
A Case Report of Acute Appendicitis Complicated by Appendicoliths
DOI: https://doi.org/10.5070/M5.52213Contrast-enhanced CT of the abdomen and pelvis was obtained. Coronal CT demonstrated a dilated appendix measuring up to 1.2 cm in diameter with multiple appendicoliths (yellow arrows), the largest measuring 1.1 cm. Mild periappendiceal fat stranding was present, consistent with acute appendicitis complicated by appendicoliths. The surrounding bowel and colon were normal in caliber and distribution. An additional coronal view demonstrated a dilated appendix (yellow arrow) containing an appendicolith with periappendiceal inflammatory changes. No evidence of perforation, abscess, or drainable fluid collection was identified.
Case Report: Acute Dyspnea in a Young Female
DOI: https://doi.org/10.5070/M5.52254The patient underwent computer tomography (CT) imaging of the chest, abdomen, and pelvis. Computer tomography of the chest showed bilateral diffuse pulmonary nodules in a perilymphatic distribution (yellow arrows), and diffusely increased mediastinal and hilar soft tissue densities (blue circle), likely representing lymphadenopathy; a left upper lobe lesion with central cavitation (orange circle) was also seen likely to be associated with the same disease process as the extensive lymphadenopathy. Imaging of the abdomen and pelvis was significant for diffuse hypodensities of the liver and spleen suggesting a multi-system process.
A Woman’s Infertility Journey Complicated by Severe Ovarian Hyperstimulation Syndrome – A Case Report
DOI: https://doi.org/10.5070/M5.52309Computed tomography (CT) of the abdomen and pelvis demonstrated pleural effusions in the lung bases (blue stars), ascites (blue stars), and enlarged ovaries with multiple cysts/follicles (white arrows). A formal pelvic US also demonstrated large volume ascites (white diamonds) and bilateral ovarian enlargement with numerous cysts. A CT angiogram (CTA) of the chest demonstrated small bilateral pleural effusions and no obvious pulmonary embolism.
