Meningioma with hemorrhagic onset: two case reports.

Haemorrhage is a rare complication of meningiomas that can occur spontaneously, after embolization, stereotactic radiation and perioperatively. Our first case was a 16 year old male, admitted with spastic quadriparesis, and retention of urine. Magnetic Resonance Imaging (MRI) revealed anteriorly placed cervical intradural extramedullary mass. Patient underwent emergency surgery following sudden worsening of neurological symptoms and intratumoral bleed was noted peroperatively. Tumor was labeled as angiomatous meningioma with hemorrhage. The second case was of a 45 year female who presented with history of sudden onset weakness in right upper and lower limb followed by unconsciousness. MRI revealed heterogeneous lesion in left parasagittal area with intratumoral bleed. Left frontal craniotomy with tumour decompression was performed. Tumour was labelled as meningothelial meningioma with haemorrhage. Meningiomas with hemorrhagic onset remain rare, and pathophysiology is still incompletely understood. Prevention and outcome of intratumoral haemorrhage highly depends on early diagnosis and adequate treatment.
