[Frontal extranasal glioma]

Extranasal gliomas are very rare tumours, being difficult to diagnose preoperatively due to the unspecific nature of symptoms and, at times, of the test. A newborn baby, prenatally diagnosed with frontal tumour, which on exploration showed a mass at the root of the nose, red-violet in colour and which seemed to become tenser. Skull x-ray and brain ultra-sound were normal. Ultra-sound of the tumour area and TAC showed a mass with solid content, with possible intracraneal communication. Faced with this possibility, removal by neurosurgical procedures was performed with no communications with SNC being observed. Histological diagnosis: extra-nasal glioma. Tumours situated at the root of the nose can have normal skin covering whose aspect is similar to the tumour mentioned above. Test carried out may not show accurately whether the tumour communicates with SNC or not, which may lead to surgical errors. We recommend that these malformations be treated directly by surgical teams which include neurosurgical specialists.
