Neurocysticercosis is a major cause of epilepsy and neurological morbidity in endemic areas of the world. It is rare in non-endemic areas, so a high degree of awareness is necessary for diagnosis. It is often benign and lesions can resolve within months. We report two children who presented in West London recently.
A 9 year old male, born in Afghanistan and resident in the UK for two years, presented with a focal seizure. He had a two month history of episodes of stiffness and weakness affecting his right arm and leg followed by right temporal headache and drowsiness. Neurological examination was normal. Computed tomography brain scan showed a 1 cm ring enhancing lesion in the left frontoparietal lobe with surrounding oedema (fig 1). Neurocysticercosis was diagnosed from the radiological findings and a positive serological test.
A 12 year old girl, also born in Afghanistan and a UK resident for six years, presented with paraesthesia of her right arm. Associated symptoms included headache, vomiting, and episodes of expressive dysphasia. Neurological examination was also normal. Magnetic resonance imaging brain scan showed a ring enhancing lesion in the left parietal lobe with surrounding oedema (fig 2).
Both children have remained well and seizure free without treatment.
