ConclusionBaseline cut off thrombus appearance predicts a  higher number of thrombectomy maneuvers. In day to day practice this may prepare the neurointerventionalist for a more challenging endovascular procedure ahead. Stroke etiology, clinical outcomes and thrombus-specific characteristics did not show any associations with the thrombus appearance.

We present the case of a 69 years-old man, with an insidious and progressive palsy of the III left CN with 6 months of evolution. CT scan revealed a 1,2 cm lesion located at the suprasellar and pre-pontine cistern at the free edge of the tentorium, initially compatible with the diagnosis of a small meningioma. He was submitted to surgery but surprisingly histopathological analysis revealed a cavernous malformation, intrinsic to the nerve.This is the twelfth reported case of an III cranial nerve CM, and the management of this lesions still doesn't have clear and definitive recommendations regarding treatment. In selected ca...

ConclusionTraumatic dACA aneurysm is a rare complication of brain trauma. Delayed intracranial haemorrhage and the sudden deterioration of neurologic function were the typical characteristics in patients with traumatic dACA aneurysm. CTA is the first-line screening modality for patients who present with intracerebral haemorrhage in the corpus callosum after trauma, particularly for patients who are older, in a poorer or critical condition. When the aneurysm is located in the A4 segment or involves a small branch, surgical trapping is the preferred definitive therapy to prevent further growth and disastrous bleeding. Early ...

AbstractObjectivesTo assess the capability of a newly developed material decomposition method from contrast-enhanced dual-energy CT images, aiming to better visualize the aortic wall and aortic intramural hematoma (IMH), compared with true non-contrast (TNC) CT.Materials and methodsTwenty-two patients (11 women; mean age, 61  ± 20 years) with acute chest pain underwent 25 dual-layer non-contrast and contrast-enhanced CT. CT-angiography images were retrospectively processed using two-material decomposition analysis, where we defined the first material as the content of a region of interest placed i...

Abstract Background: Functional assessment to rule out myocardial ischemia using coronary computed tomography angiography (CCTA) is extremely important and data on the Brazilian population are still limited. Objective: To assess the diagnostic performance of myocardial perfusion by CCTA in the detection of severe obstructive coronary artery disease (CAD) compared with single-photon emission computerized tomography (SPECT). To analyze the importance of anatomical knowledge to understand the presence of myocardial perfusion defects on SPECT imaging that is not identified on computed tomography (CT) scan. Method: A total of 3...

Abstract Clinical data: Infant, 7 months, female, referred to our department at one month of age, suspecting of congenital heart disease for further investigation. Chest radiography: Demonstrates cardiomegaly and prominent pulmonary vascular markings. Electrocardiography: Shows right ventricular hypertrophy and left anterior fascicular block. Echocardiography: Evidenced common atrioventricular valve with two orifices and the left superior pulmonary vein draining on the brachiocephalic vein. Computed tomography angiography: This complementary imaging exam was performed to confirm the diagnosis. Diagnosis: The patient presen...
