Spontaneous Intracranial Hemorrhage in Severe Hemophilia A: A Rare Cause of Seizure in a Young Child
DOI: https://doi.org/10.21980/J8G91DA computed tomography (CT) scan of the head without contrast was obtained out of concern for intracranial pathology due to the patient’s young age and the witnessed focal seizure. The CT showed a 4.2 x 1.2 x 1.5 cm acute extra-axial intracranial right frontoparietal hemorrhage favoring epidural over subdural hemorrhage given its lenticular shape. There was no underlying fracture, herniation or midline shift identified.
Gastric Volvulus
DOI: https://doi.org/10.21980/J8335FPoint of care ultrasound of his abdomen showed a large fluid filled structure with well-defined borders containing gastric contents extending from the xiphoid process to the umbilical region. No free fluid was noted on focus assessment with sonography for trauma (FAST) examination. A computed tomography (CT) scan was performed emergently and it was noted that the patient had a significantly distended stomach and gastric volvulus (blue arrows) noted in the area of his paraesophageal/hiatal hernia.
Wandering Spleen
DOI: https://doi.org/10.21980/J8PS7CHistory of present illness: A 7-month-old boy presented for evaluation of an abdominal mass. Two weeks prior, the patient had a fever followed by 24 hours of vomiting and abdominal pain, which self-resolved. His pediatrician noted the mass on exam and referred child to the emergency department (ED). His abdominal exam was significant for a hard mass palpated to the
Acute Pancreatitis
DOI: https://doi.org/10.21980/J88W5XComputed tomography of the abdomen and pelvis with contrast show edema of the pancreas (red outline) and duodenum (yellow arrow) with peripancreatic inflammation, fluid and fat stranding (blue highlight). The distal pancreatic tail was noted to appear normal (green arrow). There was no organized drainable fluid collection, and no parenchymal hypo-enhancement. These findings are consistent with moderate severity acute interstitial pancreatitis.
Renal and Splenic Infarcts
DOI: https://doi.org/10.21980/J8804KOn the coronal sections of computed tomography (CT), bilateral renal infarctions (blue arrows) and several splenic infarctions (green arrows) are noted. Of particular interest, part of the clot totally occluding the left renal artery visibly extends into the aorta (red arrow). The vascular reconstruction image is remarkable for the absent left kidney, the unusual contour of the right kidney and the abnormal splenic blush.
Saddle Pulmonary Embolus
DOI: https://doi.org/10.21980/J8N63PAn electrocardiogram (ECG) showed evidence of right heart strain with an incomplete right bundle branch block, S1Q3T3 (see red arrow [S1], blue arrow [Q3], and black arrow [T3]), and ST-segment elevation in the septal leads (green arrows). Bedside echocardiography showed a dilated right ventricle with ventricular wall akinesis (red arrow) sparing the apex (purple arrow), which is known as McConnell’s Sign. It also showed a mobile hyperechoic mass (yellow arrow). These ultrasound findings were concerning for pulmonary embolism (PE), so computed tomography (CT) angiogram of the chest was ordered and confirmed massive bilateral obstructive filling defects (red arrows) consistent with saddle pulmonary embolism. Additionally, noted is flattening of the interventricular septum (blue arrow) consistent with right heart strain. Laboratory studies were notable for a troponin-I of 0.29 ng/mL, a B-type natriuretic peptide of 792.3 pg/mL, lactic acid of 5.30 mmol/L, and a creatinine of 2.0 mg/dL, consistent with end organ dysfunction. All other lab work was within normal limits.
Sigmoid Diverticulitis Complicated by Colovesical Fistula Presenting with Pneumaturia
DOI: https://doi.org/10.21980/J80G9TA CT scan of his abdomen/pelvis shows acute sigmoid colonic diverticulitis with adjacent extraluminal collection containing gas (axial view, white arrow) consistent with perforation, along with abutment of the urinary bladder with intraluminal bladder gas (sagittal and coronal views, white arrowheads) suggesting colovesical fistula.
Beware the Devastating Outcome of a Common Procedure
DOI: https://doi.org/10.21980/J8T336Non-contrast head computed tomography (CT) demonstrates multifocal bilateral hypodense lesions (white arrows) representing air emboli. Note the lesions are located in the intra-axial distribution which indicates an underlying vascular origin.
