Primary solitary tumours of the peripheral nerve trunks are relatively infrequent. Three such tumours have been treated at Hammersmith Hospital during the last four years, but a search of the hospital records for the period 1939-1950 has not shown any similar cases. (Solitary tumours of the auditory nerve and spinal nerve roots are not included in this report.) In these three patients the tumou...

background petro-clival, clival and spheno-petro-clival tumours are still a neurosurgical challenge. usually, the classical skull base transpetrous approaches are employed, although they are burdened by an important rate of morbidity, and a very low rate of radical removal is reported. conclusions anterior transoral and transsphenoidal approaches are indicated for clival and spheno-petro-clival...

SUMMARY This retrospective study aimed to assess the percentage of complications arising in our daily practice of interventional procedures, comparing our findings with those of leading international reference centers and accepted guidelines for endovascular treatment. During the threeyear period considered (2000-2002), we performed 246 interventional procedures, divided into seven different pa...

Twenty-seven cases diagnosed as having malignant melanoma affecting the central nervous system have been studied. In 20 patients the tumours represented secondary spread from elsewhere, but there were six who had a primary melanoma either of the spinal cord, leptomeninges, or brain. Confusion exists in the literature about how to differentiate primary from secondary tumours but this suggests se...

The central nervous system (CNS) consists of the brain and the spinal cord. CNS tumours are relatively rare (<2% of all cancers and cancer deaths). Their incidence with age has two peaks, one in childhood (5-9 years) and the other >50 years where it increases with age. They can be malignant or benign. Even benign tumours can be critical due to their location in brain tissue (e.g., compressing t...

BACKGROUND Patients affected by tuberous sclerosis (TS) have a greater incidence of tumors than the healthy population. Spinal tumours in TS are reported very rarely and consist mainly of sacrococcygeal and cervical chordomas. METHOD Case report. FINDINGS A 21-year-old man, affected by TS, presented a spinal dorsal T2 tumor that caused medullary compression. He underwent decompressive lamin...
