Although pulmonary arteriovenous malformation is not a common condition, it is one of the causes of paradoxical embolism presenting with neurological manifestation. Therefore, pulmonary arteriovenous malformation should be considered in any patient with an arterial embolism, especially patients with cerebrovascular accident from an unidentified source. We report a case of paradoxical embolism o...

Glioblastoma multiforme is the most common intracranial neoplasm of all primary central nervous system tumors. Glial tumors can present in different forms. Intracranial hemorrhage may occur in all central nervous system tumors to a varying degree and extent and may even be massive. A 58-year-old man presented with intraparenchymal hemorrhage manifesting as severe headache and vomiting. Cranial ...

The posterior inferior cerebellar artery (PICA) has a unique anatomical complexity, which is of great clinical importance and involved in many pathologies, such as aneurysm, ischemic stroke, neurovascular compression syndrome (NVCS), arteriovenous malformation (AVM) brain tumour (1).
 PICA sinuous variable trajectory, divided into 5 segments. infarction usually manifests lateral bulbar mor...

Hereditary hemorrhagic telangiectasia is an uncommon autosomal dominant disease that occurs in approximately one in 5,000 to 8,000 persons. This multisystem disorder can affect the nose, skin, gastrointestinal tract, lungs, liver, and brain. Epistaxis is the most common presenting problem, occurring in 90 percent of affected patients. Approximately 15 to 30 percent of patients with hereditary h...

We report a case of unruptured arteriovenous malformation in which an extensive zone of increased signal intensity in the brain parenchyma adjacent to the nidus is demonstrated on T2-weighted MR. This area of perilesional hyperintense signal exerts a compressive effect, suggesting that it represents perilesional edema.

Eight patients with a histologically proven angiographically occult arteriovenous malformation of the brain had plain and infused computed tomographic (CT) examinations. In five cases angiography revealed a hypovascular mass and in three cases the angiogram was normal. On CT examination a high density lesion (six cases) and ventricular asymmetry (five cases) were demonstrated. In three patients...
