Dermoids are rare midline tumours. When involving the spinal cord they usually present early, in the first decade of life. We present a case of an elderly male with paraparesis. His MRI showed cord expansion at the tip of the conus medullaris; contrast enhancement with Gadolinium revealed a cystic lesion and histopathology confirmed the diagnosis of a dermoid cyst.
A 26-year-old male presented with urinary retention, spastic paraparesis and a swelling in the right side of the neck. Urinary retention was due to a neurofibroma of a lumbar spinal root compressing the urinary bladder and right ureter retroperitoneally. Paraparesis was due to an intraspinal neurofibroma causing cord compression at the cervicodorsal junction. In addition, this tumour was contiguous with the mass in the neck, and also with another large mass in the right hemithorax which was causing collapse of the right lung.
A 55 year old male presented 2 years after a jejuno-iliectomy with weakness of all limbs, paraesthesiae, and difficulty in walking. Clinical examination revealed loss of posterior column sensations. Investigations were suggestive of a deficiency of vitamin B12 and folate. MRI showed a band of hyperintensity on T2 image, in the dorsal portion of the spinal cord.
