Objective Proteus syndrome is a rare overgrowth disorder including bone, soft tissue, and skin. Central nervous system manifestations were reported in about 40% of the patients including hemimegalencephaly and the resultant hemicranial hyperplasia, convulsions and mental deficiency. We report a 1-month-old male baby referred to Pediatric Neurology Clinic Soetomo Hospital, Surabaya, Indonesia in 2014 presented recurrent seizures since birth with asymmetric dysmorphic face with the right side larger than the left, subcutaneous mass and linear nevi. Craniocervical MRI revealed hemimegalencephaly right cerebral hemisphere. Triple antiepileptic drugs were already given as well as the ketogenic diet, but the seizures persisted. The seizure then was resolved after hemispherectomy procedure.

Proteus syndrome (PS) is an extremely rare and complex disorder. Approximately 200 cases have been reported, and it seems to affect people of all ethnic and racial groups. PS is characterized by segmental overgrowth of multiple tissues and organs including vascular malformations, lipomatous overgrowth, hyperpigmentation, and various types of nevi. We hereby present a 7-year-old boy who presented with seizures and overgrowth of one-half of the body. Although classical physical features have been described, epilepsy and other neurological manifestations are rarely reported features of PS. Early detection of association of epilepsy and hemimegalencephaly with PS can prevent/minimize the neurological complications, disability, morbidity, and mortality.

Hemimegalencephaly is known to occur in Proteus syndrome, but has not been reported, to our knowledge, in the other PTEN mutation-related syndrome of Bannayan-Riley-Ruvalcaba. Here, we report a patient with Bannayan-Riley-Ruvalcaba syndrome who also had hemimegalencephaly and in whom the hemimegalencephaly was evident well before presentation of the characteristic manifestations of Bannayan-Riley-Ruvalcaba syndrome. An 11-year-old boy developed drug-resistant focal seizures on the fifth day of life. MRI revealed left hemimegalencephaly. He later showed macrocephaly, developmental delay, athetotic quadriplegic cerebral palsy, and neuromuscular scoliosis. Freckling of the penis, which is characteristic of Bannayan-Riley-Ruvalcaba syndrome, was not present at birth but was observed at 9 years of age. Gene analysis revealed a c.510 T>G PTEN mutation. This patient and his other affected family members, his father and two siblings, were started on the tumour screening procedures recommended for patients with PTEN mutations. This case highlights the importance of early screening for PTEN mutations in cases of hemimegalencephaly not otherwise explained by another disorder, even in the absence of signs of Proteus syndrome or the full manifestations of Bannayan-Riley Ruvalcaba syndrome.
