Abstract
We report a case of solitary giant multi-compartmental trigeminal neurinoma in a 10 year old female child, without the stigmata of neurofibromatosis.The child presented with headache, vomiting, dysarthria, diplopia and altered sensorium.Neuroimaging revealed a giant multi-compartmental trigeminal neurinoma measuring 6.8 x 4.3 x 4.0 cm in size. The tumor was successfully removed by single stage petrosal approach. It is extremely rare for a solitary giant neuri- noma to occur at this site in a child without neurofibromatosis. Advantages of petrosal approach in such type of tumor are discussed. As per author's knowledge, this is the largest trigeminal neurinoma reported till date in a child.
