A 22-year-old girl presented with convulsive status epilepticus and a previous history of recurrent seizures, myoclonus, ataxia and impaired cognitive functions. Neurological examination revealed rest and action-induced myoclonus, pyramidal signs and opposition hypertonia. Testing revealed severe metabolic acidosis, elevated transaminases and creatine kinase, and respiratory insufficiency. After intubation and ventilation, thiopental was introduced but the patient's condition worsened dramatically with death in a few hours. Autopsy showed profuse periodic acid-Schiff (PAS) positive intracellular inclusions in the CNS (Lafora bodies), most abundant in thalamus, cerebellum, and brainstem, as well as in other organs. Genetic testing revealed a homozygous missense mutation (c.205C > G, P69A) in the EPM2B (NHLRC1) gene, confirming the diagnosis of progressive myoclonic epilepsy Lafora-type.

Abstract
A 22-year-old girl presented with convulsive status epilepticus and a previous history of recurrent seizures, myoclonus, ataxia and impaired cognitive functions. Neurological examination revealed rest and action-induced myoclonus, pyramidal signs and opposition hypertonia. Testing revealed severe metabolic acidosis, elevated transaminases and creatine kinase, and respiratory insufficiency. After intubation and ventilation, thiopental was introduced but the patient's condition worsened dramatically with death in a few hours. Autopsy showed profuse periodic acid-Schiff (PAS) positive intracellular inclusions in the CNS (Lafora bodies), most abundant in thalamus, cerebellum, and brainstem, as well as in other organs. Genetic testing revealed a homozygous missense mutation (c.205C > G, P69A) in the EPM2B (NHLRC1) gene, confirming the diagnosis of progressive myoclonic epilepsy Lafora-type.I documenti in IRIS sono protetti da copyright e tutti i diritti sono riservati, salvo diversa indicazione.
