ABSTRACT

A 29-year-old man presented with progressive paraparesis associated with sensory impairment in both lower limbs for the past 2 years. He was experiencing the sensation of incomplete urinary evacuation. The patient had undergone an earlier operation for a lumbar lipomeningocele at birth. Magnetic resonance images of the lumbosacral spine showed a low-lying conus medullaris adherent to a caudal lipoma. There was a leash of abnormal vascular channels in the adjacent subarachnoid space. The patient underwent spinal angiography that revealed a dural arteriovenous fistula (AVF) principally fed by the left fourth lumbar (L-4) radicular branch. At surgery the cord was detethered by disconnection of the sacral lipoma. The dural fistula was obliterated by occlusion of the L-4 radicular feeder close to the nidus of the fistula. Postoperatively, the patient experienced an immediate relief of sensation of tightness in both lower limbs. There was a gradual improvement of power and sensation at the 6-month follow-up examination. According to the authors' literature search, the present case is a unique report of a rare association of spinal cord tethering due to a caudal lipoma associated with a lumbar dural AVF. The present report discusses the etiopathology, presentation, and management of this case.

ABSTRACT

An 8-month-old male infant had presented with a history of a fall from the crib a fortnight ago. He had developed progressive weakness of both lower limbs. On examination, the infant had spastic paraplegia. Magnetic resonance (MR) imaging of the cervical spine showed an epidural hematoma extending from the fourth cervical (C4) to the first dorsal (D1) vertebral level with cord compression. The patient had no bleeding disorder on investigation. He underwent cervical laminoplasty at C6 and C7 levels. The epidural hematoma was evacuated. The cervical cord started pulsating immediately. Postoperatively, the patient's paraplegia improved dramatically in 48 hours. According to the author's literature search, only seven cases of post-traumatic epidural hematoma have been reported in pediatric patients, and our patient is the youngest. The present case report discusses the etiopathology, presentation, and management of this rare case.

ABSTRACT

A 46-year-old male presented with progressive paraparesis and sensory impairment in both lower limbs since 2 months. He had urinary and bowel incontinence. On examination he had flaccid paraplegia with a sensory level at 11(th) dorsal vertebral level. Magnetic resonance imaging (MRI) scans of the lumbosacral spine showed an enhancing intramedullary lesion in the conus. The patient underwent excision of the conus mass. Histopathology confirmed the tumor to represent a poorly differentiated metastatic carcinoma from an unknown primary. A positron emission tomography-computed tomography (PET-CT) scan of the whole body revealed hypermetabolic activity in the hilum of the right lung confirmed to be a lung carcinoma on a CT-guided biopsy. The patient was undergoing chemoradiation at 1 month follow-up. The author's literature search has yielded only four other case reports of conus metastasis of which only one is in English literature. The present case report and review of literature are presented.
