Familial intradural arachnoid cysts

Abstract

✓ Two cases of intradural arachnoid cysts are reported in one family. The propositus was a 27-year-old woman with right inframammillary radicular pain and subjective weakness of the lower extremities. Her 57-year-old father was admitted with a progressive, painless paraparesis of 6 years' duration. Intradural arachnoid cysts, at T8–9 and T5–6, respectively, were found in both patients at the time of exploration.
