A 36-year-old woman admitted with a 2-week history of headaches and blurred vision. Her medical history was positive for irregular menses and hypothyroidism. Visual field tests revealed defects in the upper quadrants bilaterally and blood tests indicated slightly elevated prolactin levels (24.4; range 4.8 to 23.3), reduced morning cortisol (3.8; range 4 to 22), and reduced growth hormone levels (

A 33-years-old man was admitted to the intensive care unit because of alcoholic cirrhosis, cocaine toxicity, and septic shock to be accurately assessed. Further tests were requested. His X-ray did not show compatible patterns with pulmonary strongyloidiasis, blood culture was positive for enterobacteria that produce Klebsiella pneumoniae carbapenemase (KPC), and discrete eosinophylin hemogram and tracheal secretion culture were observed.

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 (). […]

INTRODUCTION Congenital encephalocele is a neural tube closure defect that presents herniation of cranial contents because of a cranial congenital malformation, the occipital encephalocele is the most common form of this defect.() Encephalocele often occur because of occurrence of occipital bone defect within the fourth week of embryogenesis and it can be extended for foramen magnum and affect the posterior arch of the atlas.() Hernia sac content varies and worst prognosis is large brain content inside the sac.(,) Etiology of […]

A 13-year-old patient was referred for surgical treatment of scoliosis. Her neurological examination revealed the complete loss of horizontal eye movements with normal vertical gaze, suggesting diagnosis of horizontal gaze palsy and progressive scoliosis. The magnetic resonance imaging revealed a hypoplastic pons and medulla with a prominent midline cleft, therefore resulting in characteristic “butterfly” configuration.() The tractography showed absence of major crossing pathways within the pons and midbrain, and normal interhemispheric connections in the corpus callosum (). Surgical treatment for […]

A full-term 1-day-old male newborn was admitted to the neonatal intensive care unit due to respiratory distress and cyanosis. The sepsis screen was negative and he was diagnosed as transient tachypnea of the newborn. He required supplemental oxygen for the following days and the sepsis screen was repeated and was negative. He remained in respiratory distress, particularly during feeding, and was referred to a pediatric cardiologist. On transthoracic echocardiography, the heart appeared to be structurally and functionally normal. However the […]

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 […]

This was 37-year-old woman, 10 days after surgery, who underwent breast prosthesis replacement, abdominoplasty and liposuction. Upon admission, she was hemodynamically stable, febrile and reported constant pain on left hemithorax region, but without dyspnea. An angio-CT of thoracic vessels was carried out. During intravenous injection of contrast agent, the patient was anxious and started crying during the exam. We believe that, a Valsalva maneuver was performed on inspiration apnea requested during the exam therefore causing an intrathoracic pressure that resulted […]
