[Unapparent course of pancreatitis with pseudocyst development and cholestatic jaundice in anticonvulsive therapy with valproate].

Valproic acid is a reliable and comparatively safe drug in the treatment of special forms of absence seizures. Severe but very rare complications include acute liver necrosis and acute pancreatitis which may end lethally. A case of a previously unreported association of pancreatic pseudocyst and development of cholestatic icterus in conjunction with valproic acid therapy is presented.
