A 60-year-old man with a one-year diagnosis of lung adenocarcinoma developed repetitive episodes of isolated abdominal jerking, consistent with belly dancer's syndrome (BDS) [1-3]. There was no loss of awareness. Interictal neurological examination was normal. During an episode, video-polygraphy revealed a left parietal seizure (video sequence) and neuroimaging showed left parietal metastasis (figure 1). Levetiracetam (1 g/day) resolved the seizures.
Focal aware motor seizures with abdominal clonic jerking consist of episodic, short-lasting, rhythmic movements of the abdominal wall, which are often misdiagnosed at first, owing to their rarity and heterogeneous aetiology [1-4]. As in our case, electroclinical findings indicate that seizures originate in the parietal region . Awareness of this unusual ictal semiology has important implications for diagnosis and treatment.
