[A case of cerebrotendinous xanthomatosis with convulsive seizures].
A 35 year-old male was admitted to our hospital because of convulsive seizures. His parents are first cousins. No other members of his family have similar symptoms. He showed mental retardation since childhood. At age 14, he had generalized convulsive seizures that were intractable. Bilateral cataracts were found and extracted at age 18. He noticed bilateral swellings at Achilles tendons at around 25 years of age. Physical examination revealed bilateral swellings of Achilles tendons. Neurologically, he showed poor intellectual ability, hyperreflexia with positive Babinski's sign and cerebellar ataxia. Marked elevations of cholestanol level (53.84 micrograms/ml; normal: 2.71 +/- 0.81, n = 17) and cholestanol/cholesterol ratio (2.20%; normal: 0.16 +/- 0.05, n = 17) were detected in serum. EEG showed abnormal background activities with bursts of high voltage slow theta activities. MRI study showed high intensity lesions in globus pallidus and multiple lesions in white matter with long spin echo sequence. Oral administration of chenodeoxycholic acid improved EEG findings, serum cholestanol level and convulsive seizures. However, the MRI abnormalities remained unchanged, which suggested irreversible brain damage. We reviewed the previous reports of 144 cases of CTX. Fourteen cases had convulsive seizures. We stress that CTX is one the causes of symptomatic epilepsy.
