title: Isolated dorsal column dysfunction due to an intraspinal Osteolipoma - Case report and review of literature.
abstract: Osteolipoma is a rare variant of the ubiquitous lipoma. Published literature appears in the form of isolated case reports affecting soft tissue structures in the head, neck and rarely affecting the spine. We present a unique instance of an intraspinal osteolipoma in the cervical spine, without evidence of accompanying spinal dysraphism and an atypical clinical presentation of isolateddorsal columndysfunction. We describe the clinical presentation, operative procedure and post-operative outcomes with histopathological findings of this rare entity. A 61-year-old male presented with impaireddorsal columnsensation due to an intraspinal extradural ossifying lesion in the cervical spinal canal. The patient underwent excision of the lesion with complete resolution of symptoms. Ossifying lesion in the spinal canal may be frequent finding on radiological imaging but presence of possible adipose tissue in the lesion should raise suspicion of rare clinical scenario of an osteolipoma.
