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 isolated dysfunction. 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 impaired sensation 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.

Lateral Corticospinal Tract Damage Correlates With Motor Output in Incomplete Spinal Cord Injury

“…A recent case study involving isolated spinal cord dorsal column damage due to a spinal tumor, the patient reported gait clumsiness amongst other symptoms. 23 Similarly, animal studies show that isolated dorsal column lesions contribute to poorer performance on measures of walking. 24 While not statistically significant, we found our dorsal column measure, that is GF damage, showed a negative linear trend with walking ability.…”

Lumbar Intraspinal Osteolipoma Presenting as Cauda Equina Syndrome: A Case Report and Review of Literature

“…In 2011, Yang et al first reported the successful treatment of the largest thoracic intraspinal osteolipoma [ 11 ]. Later in 2016, the second case of cervical intraspinal osteolipoma presenting as isolated dorsal column dysfunction was reported by Aiyer et al [ 12 ]. Though lipomas are common in the lumbar region, an osteolipoma has been reported only once.…”

Intraparotid Osteolipoma: Treatment Option and Surgical View

“…1 The OL has been widely described in various anatomical district sites of the body, such as the upper and lower extremities, spine, subcutaneous soft tissue and, very rarely, in head and neck region. [2][3][4][5] In particular, in the head and neck district, OL has been reported as a lesion located in the parapharyngeal space, nasopharinx, submandibular gland, eyelid, floor of the mouth, and skull base. [6][7][8][9][10] To the best of our knowledge, only 1 case of OL in the parotid region was described in literature, which was reported by Diom et al 11 in 2011, describing the case of a 21-year-old female patient with OL located in the region between the deep lobe of the parotid gland and the parapharyngeal space.…”

“…This tumor can be classified as a rare variant of lipoma, accounting for less than 1% of all cases reported in literature 1 . The OL has been widely described in various anatomical district sites of the body, such as the upper and lower extremities, spine, subcutaneous soft tissue and, very rarely, in head and neck region 2–5 . In particular, in the head and neck district, OL has been reported as a lesion located in the parapharyngeal space, nasopharinx, submandibular gland, eyelid, floor of the mouth, and skull base 6–10 …”
