An 11-year-old boy with tuberculous meningitis developed blindness, a rare complication of this disease in the United States. Magnetic resonance imaging demonstrated perichiasmal enhancement, suggesting that arachnoiditis caused the visual loss. Serial neuroimaging over 7 months revealed a persistent inflammatory process in the chiasmatic cistern, hydrocephalus, and progressive cerebral infarctions.
SUMMARY OF BACKGROUND DATA: The authors report a 46-year-old female patient who was referred to this unit for assessment of chronic postsurgical back pain. She reported severe burning pain in the lumbar region accompanied by burning pain and loss of sensation in the lower limbs. She had previously undergone lumbar spinal surgery on three occasions preceded by myelography. METHODS: Examination revealed generalized weakness and hypertonicity of both lower limbs with loss of all sensory modalities below D7. RESULTS: The MRI scanning of the thoracic spine showed an extensive complex syrinx within the thoracic cord. CONCLUSIONS: She underwent syringopleural shunting, and her condition has remained stable.
We report on an unusual case of idiopathic arachnoiditis mimicking a spinal cord tumor in a 50-year-old man with progressive paraparesis. The medical imaging work-up showed an enlarged terminal cone with adjacent cysts. Although there was no enhancement of the terminal cone or the surrounding structures, the diagnosis of spinal cord tumor was maintained and surgery was carried out. Exploration of the cauda equina and the tissue surrounding the terminal cone did not reveal a tumor. The patient improved dramatically after surgery but the symptoms recurred 1 year later. We review arachnoiditis, its pathology, and its treatment with special attention drawn to the primary form of spinal arachnoiditis.
