Granulomatous meningitis as a late complication of iodized oil myelography.
The present report is an autopsy case of an 83 year old man with severe kyphoscoliosis and granulomatous meningitis as a late complication of iodized oil myelography. He suffered from mild cognitive impairment and died of pneumonia. At autopsy, the brain showed yellow-brown granular material on its surface, mainly in the Sylvian fissure. Microscopically, granulation tissue was seen around areas of ossification encasing the foreign material. Iodized oil apparently changed into two types of foreign bodies: eosinophilic membranous lipodystrophy-like features and homogenous yellow crystals of various sizes. The pathology was identical to foreign-body granulomatous meningitis, caused by iodized oil myelography, and caused cognitive impairment in this patient.
