An Atraumatic, Idiopathic Case Report of Intraperitoneal Bladder Dome Rupture
DOI: https://doi.org/10.21980/J85S83On regular CT scan imaging, the urinary bladder is partially distended with contrast with no focal wall thickening or intraluminal hematoma. There is an intraperitoneal bladder rupture with site of rupture likely at the dome of the bladder. The bladder is outlined in red, and the bladder rupture boundaries are outlined in yellow, showing the urine as free fluid escaping into the intraperitoneal space. We also provide these findings in an axial CT in video format. On CT cystography, there is a significant amount of contrast-enhanced urine noted within the visualized peritoneal spaces. The small amount of air present anteriorly is related to the catheterization because a Foley balloon is present within the bladder. These findings are annotated with the peritoneal spaces outlined in yellow, the air in the blue outline, and the bladder in the red outline. All of these CT cystography findings are also presented in an axial view in video format.
Case Report of an Empyema Identified on Lung Ultrasound
DOI: https://doi.org/10.21980/J8SH2NUsing a curvilinear ultrasound probe, images of the patient were obtained from the left mix-axillary line. These images demonstrate a loculated left-sided pleural effusion (outlined in the attached ultrasound image in blue) that was moderate in size, concerning for an empyema. The diaphragm on the right (red) of the image outlines the inferior margin of the collection of pus, which is seen in the inferior aspect of the left lung. Unfortunately, rib shadows on the left side of the image prevent the full empyema from being captured in this single image. As a result of the bedside ultrasound, however, the patient was rapidly diagnosed with an empyema and was initiated on antibiotics, which is further discussed below. After his bedside ultrasound was completed, his chest x-ray revealed the expected left-sided pleural effusion. Additionally, a CT angiogram of the chest was ordered to rule out a pulmonary embolism, which was negative for an embolism but does redemonstrate the left-sided loculated pleural effusion (outlined on the CT axial and coronal images in blue).
A Case Report of Neonatal Vomiting due to Adrenal Hemorrhage, Abscess and Pseudohypoaldosteronism
DOI: https://doi.org/10.21980/J8QQ0BAn ultrasound (US) of the abdomen was obtained to evaluate for possible pyloric stenosis (see US transverse/dopper imaging). While imaging showed a normal pyloric channel, it revealed an unexpected finding: a complex cystic mass arising from the right adrenal gland (yellow outline), measuring 5.8 by 4.0 by 6.4 cm with calcifications peripherally and mass effect on the kidney without evidence of vascular flow (blue arrow). Computed tomography (CT) of the abdomen/pelvis with IV contrast was subsequently obtained and measured the lesion as 2.8 by 4.6 by 4 cm without evidence of additional masses, lymphadenopathy or left adrenal gland abnormality (see CT axial, coronal, and sagittal imaging).
Case Report of Unusual Facial Swelling in an 8-Month-Old
DOI: https://doi.org/10.21980/J8M06FFacial ultrasound revealed local inflammatory changes such as increased echogenicity and heterogeneity in the soft tissues of the right cheek, suggestive of soft tissue edema. There was evidence of a prominent right parotid gland with increased heterogeneity suggestive of a traumatic injury. Additionally, facial ultrasound demonstrated a 6mm ill-defined anechoic collection within the right cheek without increased doppler flow (green arrow), thought to represent a focal area of edema instead of an abscess.
Case Report: Thoracic Aortic Dissection in a Previously Healthy Male with an Unusual Inciting Factor
DOI: https://doi.org/10.21980/J8G92SA non-contrast computed tomography (CT) scan was negative for a suspected ureteral stone. However, there were aortic calcifications visualized at the infrarenal level that were notable given the patient’s age (red arrow). Given this finding in conjunction with the patient’s symptoms, bedside transabdominal ultrasonography was performed which revealed an intraluminal echogenic flap within the aorta near the common iliac arteries. CT angiography (CTA) with delayed contrast protocol revealed an extensive Stanford type A aortic dissection with involvement of the aortic root (purple arrow), brachiocephalic trunk, ostia of the left subclavian artery, descending aorta (blue arrow), bilateral common iliac arteries, and left internal iliac artery.
Case Report: Altered with PRES
DOI: https://doi.org/10.21980/J8NW73On vitals, the patient was found to be consistently hypertensive to the 230s/160s. Point-of-care glucose was within normal limits. Noncontrast CT imaging of the head revealed no acute intracranial hemorrhage or evidence of ischemic stroke, but was remarkable for areas of biparietal subcortical low-attenuation (white arrows), concerning for PRES. Patient subsequently underwent CT angiogram imaging of the head with perfusion which revealed no large vessel occlusion.
A Case Report of Cardiac Tamponade
DOI: https://doi.org/10.21980/J8J644The patient was in noticeable respiratory distress and had oxygen saturation of 94% on room air. Bilateral jugular venous distention with severe right supraclavicular lymphadenopathy and diffuse bilateral wheezing was present. Although muffled heart sounds and hypotension are part of Beck’s Triad, these were not present in this case. Electrocardiogram obtained on arrival showed a sinus tachycardia with low-voltage QRS complexes and electrical alternans. Low voltage QRS can be seen on the ECG provided and is demonstrated by the low amplitude of the QRS complexes seen on all the leads. Electrical alternans may have an alternating axis or amplitudes of the QRS complex. Alternating axis is best visualized in V4-V6 on this ECG while alternating amplitudes are seen throughout the rest of the ECG. Computed tomography angiogram (CTA) of the chest revealed a large pericardial effusion with bilateral pulmonary emboli and a right upper lobe mass. A bedside transthoracic echocardiogram (TTE) was then performed and confirmed the large effusion, but also showed right ventricular collapse during diastole, indicative of cardiac tamponade.
A Different Type of Tension Headache: A Case Report of Traumatic Tension Pneumocephalus
DOI: https://doi.org/10.21980/J8DH0GCT head without contrast demonstrated a minimally displaced fracture of the frontal sinuses at the midline underlying his known laceration that involved the anterior and posterior tables of the calvarium. This is seen on the sagittal view and indicated by the blue arrow. There was a small volume of underlying subarachnoid hemorrhage along the falx. There was also extensive pneumocephalus most pronounced along the bilateral anterior frontal convexity associated with the frontal sinus fracture, seen on the axial image and indicated by the red arrow. This pattern of air is commonly referred to as the “Mount Fuji” sign.6 Other intracranial air can also be seen on the sagittal image and is indicated by the white arrow.
