“…Therefore thorough knowledge of variant venous anatomy is necessary to avoid misinterpretation of normal veins as DVAs 5). However, this characteristic of CT angiography may identify DVAs.…”

ObjectiveDevelopmental venous anomalies (DVAs) are benign anatomic variations; therefore, they are usually discovered incidentally. The aim of this article was to describe radiological findings of DVAs.MethodsA retrospective search for DVAs of the brain was performed in 1899 patients who had undergone magnetic resonance imaging (MRI) with contrast enhancement between January 1, 2005 and April 25, 2011. We also reviewed the results of computed tomography (CT), magnetic resonance angiography (MRA), CT angiography, and transfemoral cerebral angiography (TFCA) studies performed in patients with DVAs.ResultsThirty-two DVAs were identified in 31 of the 1899 patients (1.63%). These 31 patients underwent five enhanced CTs, three MRAs, two CT angiographies, and two TFCAs. Thirty of the 32 DVAs were supratentorial (ST) and two were infratentorial (IT). All enhanced MRI studies exhibited excellent resolution of DVAs. All DVAs had only one draining vein. The venous drainage system was an IT vein in three DVAs and an ST vein in 29 DVAs. Two out of five enhanced CTs presented good visualization of the draining vein. None of the MRAs, including the source image, revealed the presence of DVAs. The two CT angiographies exhibited good resolution of DVAs. One of the two TFCAs yielded an excellent illustration of the DVA.ConclusionCT angiography and MRI with contrast enhancement yielded detailed findings of DVAs. In contrast, MRA did not identify the DVAs. Enhanced CT presented only the draining vein of DVAs.

“…performed for further evaluation of intracranial bleeding and incidentally reveals an unsuspected DVA. 38 The appearance (linear or dots) reflects the classical large transcortical vein that drains into a dural sinus or deep ependymal vein; some may also have the classical ''medusa head'' or ''palm frond'' appearance of radiating smaller veins.…”

Nontraumatic spontaneous intracranial hemorrhage occurs most commonly into the subarachnoid space and brain parenchyma, in contrast to subdural and epidural hematomas that are usually traumatic. The differential diagnosis of nontraumatic subarachnoid hemorrhage includes intracranial aneurysm rupture and vascular malformations, both of which may be investigated noninvasively with computed tomography and magnetic resonance imaging. An isolated intraparenchymal hematoma may be caused by hypertensive vasculopathy, amyloid angiopathy, vascular malformations, or by primary or secondary neoplasms. Knowledge of the appearance of intracerebral vascular malformations will help clinicians request appropriate further imaging and direct treatment.
