We report imaging findings of posterior fossa DVA with a thrombosed drainage vein

in a patient with nonhemorrhagic cerebellar infarct. We also review the relevant GW-572016 concentration literature on the subject. “
“The 2-deoxy-2-[18F] fluoro-D-glucose positron emission tomography (FDG-PET) scan is commonly used in detection and staging of many malignant neoplasms. However, several benign or non-neoplastic conditions avidly accumulate 18F-FDG, causing ambiguity in interpretation of results. It is unknown whether pituitary adenomas uptake 18F-FDG and appear positive in PET imaging. Here, we present 2 cases of benign pituitary adenoma with elevated metabolic activity in 18F-FDG PET scan. Medical, neurologic, and psychiatric histories; physical examination findings;

laboratory work up results; and pathologic and imaging studies were documented. The 18F-FDG-PET images revealed foci of marked PLX4032 clinical trial FDG uptake in pituitary adenomas of 2 patients. Pituitary micro- and macro-adenomas may present as hypermetabolic foci on 18F-FDG PET scan. “
“Primary intracranial malignant fibrous histiocytoma (MFH) is an extremely rare entity. A few reported cases have been associated with factors such as a previous history of radiation therapy or surgical trauma. We report on a rare case of intracerebral MFH in a previously healthy 47-year-old man, which was initially presumed to be a high-grade glioma. Conventional as well as advanced magnetic resonance sequences, including diffusion-weighted image and

perfusion-weighted image, were used in characterization of the mass. “
“A 31-year-old male patient admitted to another hospital for investigation of a localized painful hump in the medial surface of his left leg. The clinical examination revealed a painful palpable lump in the medial surface of left thigh that was initially thought to be a hematoma due to a history of recent trauma. However, an ultrasound was requested to find more exclude deep venous thrombosis (DVT). The US examination revealed a heterogeneous, fusiform lesion with elongated proximal and distal projections in close proximity to superficial femoral artery and vein and could not definitely exclude the DVT hypothesis. In a second ultrasound examination performed in our department, a neurogenic origin of the lesion was proposed. A consequent MRI examination confirmed the presence of a fusiform tumor in the anatomic path of the saphenous nerve. This was further confirmed intraoperatively, and pathologically was diagnosed as a malignant peripheral nerve sheath tumor (MPNST). In this present study the role of ultrasonography, the correlation between MRI and ultrasonographic findings are discussed and a review of the literature is presented. “
“It is still controversial whether intravenous (IV) thrombolysis for acute ischemic stroke increases the risk of aneurysmal bleeding.
