A 34-year old male patient, victim of motorcycle accident at about 56 miles/hour, was brought into emergency care with a cervical collar. He was hemodynamically stable, with no respiratory or neurological impairment, complaining of diffuse moderate intensity abdominal pain during the physical examination. During secondary evaluation, abrasions were identified on the abdominal wall in the right flank area. Due to high energy trauma, he underwent a whole body computed tomography (CT) that showed an hematoma in the mesenteric fat planes […]

A 56-year-old male patient, hypertensive, diabetic and asymptomatic, underwent abdominal computed tomography (CT) with intravenous contrast for follow-up of hepatic steatosis. Computed tomography demonstrated a solid hypervascular nodule in the pancreatic head (characteristics of neuroendocrine lesion – ) and oval formation anteriorly to the aortoiliac bifurcation (). In this situation, axial CT can mimick lymph node enlargement, especially in clinical oncology context. However, evaluation of the different phases of the exam and the reformatted coronal and sagittal images help making […]

A 46 years old man, complaining about abdominal pain, was submmited to a magnetic resonance having a giant liver hemangioma as an incidental finding (). In the follow-up, after 6 years, we observed in a T2-weighted sequence volumetric reduction of lesions’ signal in T2-weighted image () was observed. Temporal evolution, associated with imaging features, indicated sclerosed/hyalinized hemangioma (). […]

We report a case of a 56-year-old male under investigation for large lytic lesion at clivus. After lesion resection, patient was referred to abdominal computed tomography scan for metastasis screening. The lesion was posteriorly characterized as chondroid chordoma at histopathology examination. On non-enhanced computed tomography, multiple hypottenuating nodules of different sizes were seen; the largest nodule had 3.2cm. On post-contrast phases lesions had similar enhancement to adjacent liver parenchyma. However, no significant mass effect or invasiveness were seen, once vascular […]
