Basilic vein aneurysm mimicking as arterio venous malformation

Venous aneurysm is saccular or fusiform dilatation of vein, usually congenital origin. Among acquired variety post intravenous cannulation leading to venous aneurysm is extremely rare entity. Non invasive diagnostic procedure MRI and duplex scanning are very useful modality for anatomical localization of the aneurysm. Although an ascending venogram is an invasive test and should take a backseat for diagnosis of such aneurysm. Symptometic case needs surgical management. Anatomical delineation is an important pre requisite for planning surgery. Aneurysmorrhaphy preserves the affected venous segment because it does not produce luminal compromise.
