A developmental venous anomaly presenting atypical findings on susceptibility-weighted imaging.
Findings on Susceptibility-Weighted Imaging Developmental venous anomaly (DVA) is the most common type of vascular malformation found at autopsy, with a prevalence of 2%. DVA is composed of radially arranged venous complexes converging to a centrally located venous trunk, which drains the normal brain parenchyma. Susceptibility-weighted imaging (SWI) shows low signal intensity for DVA due to th...

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...
متن کاملDevelopmental Venous Anomaly Associated with Hemi-Parkinson’s Syndrome
Objective and Importance: Developmental venous anomalies (DVAs) are common congenital anomalies of intracranial venous drainage. In general, it is felt that DVAs replace the normal venous drainage system and, unless associated with another lesion such as a cavernous malformation, should not produce symptoms. The present case raises important questions regarding the potential for DVAs to become ...
متن کاملComplex Partial Epilepsy Associated with Temporal Lobe Developmental Venous Anomaly.
BACKGROUND Developmental venous anomalies (DVA) are found incidentally but sometimes patients with these anomalies present with varying degrees of neurologic manifestations. OBJECTIVE We report a patient with early onset complex partial epilepsy and associated DVA and discuss the natural history, neuroimaging and clinical characteristics, and management. CASE DESCRIPTION A 21-year-old man p...
متن کاملThe developmental venous anomaly associated with the cavernous malformation.
A magnetic resonance imaging (MRI) study was ordered in a 32-year-old man with a 6 month history of double vision and confirmed left abducens nerve palsy on neurological examination. Non-enhanced T1 and T2-weighted images revealed the presence of a cavernous malformation (CM) in the left lateral aspect of the mesencephalon (mostly in the left inferior colliculus), associated with a large blood ...
