Regrowth of Cervical Intradural Lipoma without Spinal Dysraphism

A 49 years old male patient who suffered from deterioration of posterior neck pain, left hand numbness, left lower limb pain and gait disturbance for 3 years visited our outpatient department. He had been diagnosed as non-dysraphic cervical intradural lipoma and operated in August 1990. On the radiologic images, we found the regrowth of non-dysraphic cervical intradural lipoma from C2 to C7 level, which surrounds and compresses the cervical spinal cord. Previous subtotal laminectomy from C2 to C7 and severe cervical lordosis were also found. Appropriate debulking of lipoma mass without duroplasty was successfully done with intraoperative neurophysiological monitoring (IONM). We are following up the patient for 24 months via outpatient department, his neurologic symptoms such as hand numbness, gait disturbance, left lower limb pain and posterior neck pain have improved. We describe a rare case of regrowth of non-dysraphic cervical intradural lipoma.

Cervico-Thoracic Intradural Extramedullary Lipoma

A 42-year-old female was admitted with an 11-month history of progressive spastic paraparesis and ataxic gait. Magnetic resonance imaging showed intraspinal space occupying lesion compressing the spinal cord posteriorly, located from C5 to T2 with iso to high signal intensity at T2-weighted images and high signal intensity at T1-weighted images. The patient underwent surgery for decompression of the affected spinal cord because of the progressive neurological deficit. At surgery, the lesion was intradural extramedullary lipoma composed with mature adipose tissue. Partial tumor removal to decompress the neural structures and laminoplasty to avoid postoperative instability and deformity were performed. Postoperatively, she demonstrated improvement in paraparesis and was able to walk without assistance. Though attempts to decrease the size of or even to totally remove a lipoma are not required to achieve satisfactory results and carry considerable risks of surgical morbidity, a careful and limited decompression of the affected spinal cord through a partial removal of the tumor and laminoplasty could result in a significant neurological improvement.

A Case of Intradural Spinal Lipoma

Intradural spinal lipomas are rare, primary genign tumor of the spinal canal. A case of intradural spinal lipoma with intramedullary extension is presented. Clinical feature was slowly progressing paraparesis. A subtotal excision was performed, and pathological studies confirmed the diagnosis.

Spinal lipoma.

One patient, 64 years old, with progressive bilateral sensory loss and motor weakness of both upper and lower extremities was reported. By physical examination, upper spinal cord lesion was suspected. The definite diagnosis, spinal lipoma, was based on the investigation MRI which demonstrated the position, contour and type of tissue of the lesion and surrounding structure also.

A Case of Large Cervical Intradural Lipoma with Externsion into the Posterior Fossa

Intraspinal lipomas are rare, benign neoplasms, comprising less than 1% of all intradural spinal tumors. Such tumors occur in the thoracic and cervical region, however, extension into the posterior fossa is most unusual. A case of large cervical intradural spinal liplma with extension into the posterior fossa in adult female is presented. Clinical feature was slowly progressing quadriparesis. Brain and cervical spine computed tomography confirmed the diagnosis and Magnetic resonance imaging was very useful for delineation of the anatomy of the lipoma as an aid in planning the operation. Operative therapy consisted of combined suboccipital craniectomy, spinal laminotomy and laminoplasty, subtotal tumor decompression.
