Hypervascular neurofibromas in a case of neurofibromatosis type 1 - a case report

Neurofibromatosis type 1 is one of the most frequently inherited diseases affecting 1:3500 newborn. The diagnosis of Neurofibromatosis type 1 is not dilemmatic because of typical clinical features. The key feature of Neurofibromatosis type 1, neurofibromas, are complex tumours arising from peripheral nerve sheaths. Neurofibromas may be focal growths or can extend along the length of a nerve, involving several fascicles and including nerve branches. Neurofibromas sometimes exhibit hypervascular characteristics. Few reports suggest the bleeding tendency observed in neurofibroma, although not common, occasionally causes a large amount of bleeding during surgical intervention. Hypervascular characteristics of these tumors may be a confusing factor for the diagnostician. This report describes the case of Neurofibromatosis type 1 presented with neurofibroma exhibiting hypervascular characteristics and emphasizes the importance of necessary investigations prior to surgical procedures.
