Necrotizing Fasciitis and Mediastinitis after Wisdom Tooth Extraction: A Case Report
DOI: https://doi.org/10.21980/J8XW7KComputer tomography (CT) imaging of soft tissues of the neck and of the chest/abdomen/pelvis revealed extensive swelling and subcutaneous air (see red arrows) on the left side of the face and neck extending to the left shoulder, as well as parapharyngeal/retropharyngeal spaces and posterior/superior mediastinum.
Adult Clavicular Fracture Case Report
DOI: https://doi.org/10.21980/J8FM0TThe patient's chest and clavicular radiographs showed a comminuted displaced acute fracture of the right mid-clavicle (green, blue, yellow). The clavicular fracture was also visible on the chest computed tomography (CT). The remainder of his trauma workup was negative for acute findings.
A Case Report of Ogilvie’s Syndrome in a 58-year-old Quadriplegic
DOI: https://doi.org/10.21980/J82922Plain radiograph of the patient's abdomen revealed a gaseous distention of the colon. This is demonstrated as noted in the abdominal x-ray as gaseous distention, most notably in the large bowel (arrows) including the rectal region (large circle). Follow up computed tomography (CT) scan affirmed severe pancolonic gaseous distention measuring up to 11.2 cm, compatible with colonic pseudo-obstruction as noted by the large red arrows. No anatomical lesion or mechanical obstruction was observed, as well as no evidence of malignancy or other acute process.
Cecal Volvulus Diagnosed with a Whirl Sign: A Case Report
DOI: https://doi.org/10.21980/J8XM05The CT image demonstrates a “whirl sign” (red arrow) which is indicative of a volvulus. This image occurs when bowel, mesentery and vasculature rotate around a transition point causing an image similar to a hurricane on a weather map. When seen on a CT scan, a whirl sign suggests a high likelihood of either a closed loop bowel obstruction or volvulus in the cecum, sigmoid or midgut. In any of the cases, seeing a whirl sign strongly increases the need for emergent surgical management.
Case Report of Spontaneous Thyroid Hemorrhage Following LMA Insertion
DOI: https://doi.org/10.21980/J8XP8WTwo photographs of patients neck, both showcasing no obvious erythema, bruising, or swelling which is noteworthy because there is potential for airway compromise but there was nothing visible to indicate that on exam.
CTA of neck showing thyroid nodule and potential thyroid hemorrhage (outlined in orange) on the left without evidence of airway compromise at the time of CT scan. Official read by attending radiologist states there is a “heterogeneous left thyroid nodule measuring 3 cm. Findings are suggestive of multinodular goiter with possible acute hemorrhage. Adjacent tract of soft tissue stranding in the anterior left neck with mild adjacent fascial thickening. This could represent small amount of hemorrhage or could be inflammatory.”
Caught on CT! The Case of the Hemodynamically Stable Ruptured Abdominal Aortic Aneurysm
DOI: https://doi.org/10.21980/J8B07BThe associated images demonstrate the transverse, sagittal, and coronal views of a 6.8 cm infrarenal ruptured AAA continuous with a 4 cm right common iliac aneurysm (transverse, sagittal and coronal). Active hemorrhage was seen contained within the aortic wall, and retroperitoneal bleeding can be appreciated with asymmetric enlargement of the left psoas muscle (coronal - red arrow).1 Plaque and calcifications with a residual opacified true lumen is also present (transverse – red star, sagittal – red arrow). Known as the tangential calcium sign, this is a common radiologic finding of AAAs.2
Post-Coital Sudden Cardiac Arrest Due to Non-Traumatic Subarachnoid Hemorrhage—A Case Report
DOI: https://doi.org/10.21980/J8663NThe electrocardiogram demonstrated sinus tachycardia with ST segment elevation in lead aVR (black arrows) and diffuse ST depressions concerning for possible ST elevation myocardial infarction (STEMI). Given the events reported and the patient’s neurologic exam without sedation, non-contrast CT of the head was ordered; imaging showed evidence of a large subarachnoid hemorrhage, mostly at the level of the Circle of Willis (black arrow) concerning for an aneurysmal bleed as well as mild generalized white matter density suggestive of cerebral edema.
A Case Report of Epidural Hematoma After Traumatic Brain Injury
DOI: https://doi.org/10.21980/J8R059Non-contrast CT head demonstrated a right sided EDH (red arrow) with overlying scalp hematoma, left-sided subdural hematoma (blue arrow), and bilateral subarachnoid hemorrhages. No skull fractures were noted.
A Case Report on Miliary Tuberculosis in Acute Immune Reconstitution Inflammatory Syndrome
DOI: https://doi.org/10.21980/J81H02A portable single-view radiograph of the chest was obtained upon the patient’s arrival to the ED resuscitation bay that showed diffuse reticulonodular airspace opacities (red arrows) seen throughout the bilateral lungs, concerning for disseminated pulmonary tuberculosis. Subsequently, a computed tomography (CT) angiography of the chest was obtained which again demonstrates this diffuse reticulonodular airspace opacity pattern (red arrows).
Rapid Airway Narrowing Associated with Hodgkin’s Lymphoma
DOI: https://doi.org/10.21980/J86D3QNeck X-ray showed nonspecific significant prevertebral soft tissue swelling at the level of the cervical spine, with associated apparent thickening of the epiglottis (yellow arrow), diffuse soft tissue swelling of the neck (red arrows) and tracheal airway narrowing (light blue arrow). The computed tomography imaging of the neck was significant for multiple conglomerating pathological lymph nodes with a significant mass effect (orange arrows) compressing the right internal jugular vein (green arrow).
