Abstract
- Cerebrotendinous xanthomatosis (CTX) is a rare, autosomal recessive lipid-storage disease with
abnormal deposition of cholesterol and cholestanol in multiple tissues. The disease is caused by mutations in
the sterol 27-hydroxylase and characterized by tendon xanthoma, premature cataracts and various neurological
manifestations in the central and peripheral nervous systems. A 47-year-old man presented with unsteadiness
of gait and weakness on extremities. He had a bilateral cataract extraction at the age of 30 years. Physical
examination revealed bilateral elongated mass on Achilles tendons. On neurologic examination, dysarthria, spastic
quadriparesis and exaggerated deep tendon reflexes were noted. Surgical excisional biopsy of Achilles tendon
revealed a crystalline clefts surrounded by many multinucle-ated giant cells. A moderate degree of cerebral and
cerebellar cortical atrophy and focal high signal intensities in sub-cortical white matter were noted on T2-weighted
magnetic resonance images. Serum cholestanol was elevated (22 Mg/ml ; normal <2 Mg/ml), while serum
cholesterol was normal (186 mg/dl ; normal <250 mg/dl). With clinical, radiologi-cal and biochemical findings,
we confirmed a rare case of cerebrotendinous xanthomatosis.
