fell out of the top of his bunk bed 3 days ago and is now seizing. Axial (above left) and coronal (above right) CT without contrast of the brain shows a large round high density lesion in the left middle cranial fossa. Axial T1 MRI without contrast of the brain (below left) shows the lesion to have mixed signal intensity while the axial gradient echo MRI (below right) shows a low signal intensity ring around the lesion representing hemosiderin deposition.The diagnosis was cavernous malformation with subacute and chronic hemorrhage in the left temporal lobe.

Cavernous venous malformation, also traditionally referred to as a cavernous hemangioma (despite it not being a tumor) or cavernomas, are non-neoplastic slow flow venous malformations found in many parts of the body.

Terminology

Despite the ubiquity of use of the traditional terms cavernoma, hemangioma and cavernous hemangioma, they represent outdated and misleading nomenclature no longer recognized in the ISSVA classification of vascular anomalies.

Having said that when reporting it is probably safest to include the 'traditional' term in brackets for clarity, for example, "features are those of a slow flow venous malformation (cavernous venous malformation/cavernoma)"

Regional manifestations

Their radiographic appearance, epidemiology, clinical presentation and treatment are specific to the tissue/organ in which they are found and as such these are discussed individually according to location.
