We report a rare occurrence of central nervous system hydatid disease involving the occipital lobe caused by Echinococcus multilocularis in an immunocompetent rural tribal man. A 40-year-old man presented with gradual onset of headache for 6-month duration with associated seizures and giddiness. Neurological examination revealed cerebellar signs with visual field defect. Magnetic resonance imaging revealed a multilobulated cystic lesion with membranous septations and peri-lesional oedema involving the left occipital lobe. Wet mount examination of the aspirated cystic fluid showed multiple daughter cysts and hooklets with histopathological examination showing features suggestive of hydatid disease. The identification of the causative organism was confirmed as E. multilocularis by conventional polymerase chain reaction. The patient's condition improved during the post-operative period and was discharged 2 days later, on oral albendazole for 3 months. At 2 years follow-up, the patient neurological symptoms have recovered with minimal visual field defect.
