Visual Case Report of a Prosthetic Joint Infection and Chronic Dehiscence following a Total Knee Arthroplasty
DOI: https://doi.org/10.5070/M5.52251Radiographs demonstrated intact prosthetic components (blue) without acute fracture, tibial peri-stem lucency (green) concerning for loosening or infection, as well as joint effusion, and soft-tissue swelling.
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).
A Case Report of Rare Bilateral Quadriceps Tendon Rupture Diagnosed by Point of Care Ultrasound (POCUS)
DOI: https://doi.org/10.5070/M5.52334Musculoskeletal assessment with POCUS revealed disruption of the left quadriceps tendon (blue arrows) indicated by a large hypoechoic gap (red arrow) with significant surrounding fluid throughout the quadriceps as well as a sizable left knee effusion (orange highlighting). The right lower extremity had a disrupted and retracted quadriceps tendon (yellow arrow) with associated fluid near the injury site and a small right knee joint effusion (orange highlighting). Therefore, he was diagnosed with bilateral quadriceps tendon ruptures.
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.
A Case Report of a Coin Stack Masquerading as a Button Battery
DOI: https://doi.org/10.5070/53886The two images provided are OSH AP and lateral XRs of the patient's neck. The OSH AP view demonstrates a halo sign (green arrow), while the lateral view demonstrates a step-off sign (stick figure). These are key findings with BB ingestions. The halo sign is the presence of two concentric rings on an anterior view XR.
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 Granulomatosis with Polyangiitis Presenting with Chronic Conjunctivitis
DOI: https://doi.org/10.5070/M5.52284Notable bilateral proptosis with conjunctival injection and limbic sparing (clear conjunctiva surrounding the margin of the cornea, shown by the arrow in the image of the eyes) was present.
Caught in the Whirl: A Case Report of Midgut Volvulus in an Elderly Patient
DOI: https://doi.org/10.5070/M5.52361An upright chest x-ray demonstrated air underneath the diaphragm bilaterally (yellow arrows), enhancing the diaphragmatic contour. A computed tomography angiography (CTA) abdomen and pelvis showed scattered pneumoperitoneum (red arrow), dilated segments of small bowel (orange arrow), and clockwise swirling of the mesentery (blue arrow), concerning for mesenteric volvulus with possible bowel perforation.
