developmental venous anomaly (dva) is a common lesion formerly known as venous angioma. dvas drain normal brain parenchyma; however, parenchymal abnormalities surrounding dvas have been reported. unilateral putamen and caudate calcification in the drainage territory of dvas has so far been reported in 7 cases, all with deep venous drainage. we present two additional cases of dvas, one with supe...

Dr. Rômulo L. Gama – Rede Sarah de Hospitais de Reabilitação Avenida Presidente Juscelino Kubitscheck 4500 60861-630 Fortaleza CE Brasil. E-mail: [email protected] Developmental venous anomaly (DVA), also known as venous angioma, is becoming the most commonly encountered intracranial vascular malformation in central nervous system (CNS) imaging. It is thought that DVA develops during developm...

Forty seven cases of central nervous system cavernous angioma (21 males and 26 females) are described. The main clinical signs were epilepsy and brainstem syndromes. Digital subtraction intra-arterial angiography, when used, failed to reveal cavernoma. CT detected many of the lesions, but the most successful supplementary diagnostic procedure was MRI which produces highly characteristic images ...

In this issue of AJNR, Wilms et al ( 1) add to the ongoing debate whether the venous angioma, more recently called developmental venous anomaly (2), can be symptomatic, whether it alone can bleed, or whether such hemorrhage occurs because of the concomitant occurrence of a cavernous angioma . This debate is not just semantic. It is essential to pathophysiologic understanding of a given lesion s...

human infection with echinococcus granulosis is a common disease throughout south america, the mediterranean littoral, the middle east, central asia and east africa, which usually occur in children and young adults. formation of avascular cystic lesions in the liver, kidney, pancreas, bones, vitreus and brain can cause protean of signs and symptoms. intracranial cysts usually present with focal...

we describe a 40-year-old woman presenting with headache, nausea, episodic amnesia and blurred optic disc. brain mri disclosed diffuse leptomeningeal enhancement. csf analysis showed aseptic meningitis with elevated ace level. neurosarcoidosis was diagnosed based on granulomatosis changes on tissue biopsy.

background & objectives: the accurate assessment of the diseased tissue is fundamental to the diagnosis and management of disorders of the central nervous system (cns). the ‛squash’ or ‛crush’ technique has been universally employed in the intraoperative diagnosis of cns tumors. the aim of our study was to evaluate the accuracy of squash preparation in diagnosing cns tumors by comparing wit...

A 17-year-old male and a 28-year-old female presented with cavernous angioma and venous angioma colocated in the same region, and manifesting as convulsions. The cavernous angiomas were extirpated without damage to the venous angioma. No postoperative neurological deficits were observed. The patients have been free of convulsions without anticonvulsant medication for 2 years. Early extirpation ...
