A 45 year old gentleman presented with inability
to smell for 20 years and recent onset alteration of memory. MRI Scan of his
brain showed a Large Tumour at the base of the brain, behind the forehead – a Basi-Frontal
Meningioma.
The tumour was removed completely and the
patient recovered nicely. Histopathology (microscopic assessment of the tumour
tissue by Neuro-Pathologist) showed a Transitional Meningioma (WHO grade I) – a
benign tumour.
These tumours have a rich blood supply and
are prone to bleeding during surgery. The nerves of smell along with centres
for memory, behaviour and continence are located in this area of the brain. The
nerves of vision as well as blood supply to one’s legs are closely related.
Therefore, careful removal of the tumour by microsurgical technique is
essential to avoid damaging these structures.
