Intramedullary cavernoma with extralesional haemorrhage

Intramedullary cavernomas are rare lesions constituting 5 to 12% of all intramedullary tumours. they are more recognized after introduction of magnetic resonance imaging and detection rates have improved by advance techniques. they may be solitary or multiple or may have associated cranial lesions. they may present with gradual neurological decline or with acute loss of spinal function. in addition neurological deficit depends on the location of the lesion within the spinal cord. we are reporting the case of a 45 year old male who presented with neck pain and progressive right arm weakness with numbness. mri cervical spine with contrast showed intramedullary lesion with peripheral t2 hypointense rim and extralesional haemorrhage consistent with cavernoma. patient underwent successful surgery and his symptoms markedly improved with mild residual grip weakness in right hand. © 2017,pakistan medical association. all rights reserved.
