A previously healthy 11-year-old female child presented with a progressively increasing headache for 15 days. There was no history of ataxia, nystagmus, and weakness. There were no visual problems or chronic upper respiratory problems indicative of sinusitis. Examination revealed the absence of hypertension, bradycardia, and abnormal breathing pattern. The Glasgow Coma Scale was 15/15. There were no significant neurological findings apart from the bilateral 6th nerve palsy. The fundus was normal. Systemic examination was normal. A magnetic resonance imaging of the brain was planned considering a structural central nervous system lesion.

The magnetic resonance imaging revealed a large (42 mm × 39 mm × 42 mm), well-defined, cystic lesion in the left frontal lobe, with a regular wall and collapsed intra-luminal membrane. Surrounding white matter edema, mass effect with herniation, and right ventricular dilatation were noted [Figure 1]. The primary radiological differential diagnosis was a cerebral hydatid cyst. Additional investigations like a chest X-ray and abdominal ultrasonogram excluded hydatid cysts elsewhere at other likely sites. The IgG anti-Echinococcus antibody titres were normal. The intact cyst was removed surgically [Figure 1]a and [Figure 1]b and [Figure 2] using the Dowling technique, followed by oral Albendazole as per standard protocol. Histopathology confirmed the diagnosis. The child was discharged uneventfully, is on follow-up and is asymptomatic.

Hydatid disease is caused by Echinococcosis, the larval stage of a tapeworm Echinococcus granulosus.[1] Humans get infected accidentally through Feco-oral route via direct contact with an infected dog. Four species infect humans with the respective presentations: E. granulosus (cystic echinococcosis), Echinococcus multilocularis (alveolar echinococcosis), Echinococcus oligarthus, and Echinococcus vogelix (polycystic hydatid disease). The most common affected sites are the liver (75%) and lungs (15%) followed by the spleen, kidney, heart, bones, and brain (10%). Brain hydatid cysts can be primary (single) or secondary (multiple). Clinical manifestations are usually due to elevated intracranial pressure and/or mass effect. Focal neurological deficits may occur depending on the location and size. Definitive diagnosis is by detection of IgG anti-Echinococcus antibodies using enzyme-linked immunosorbent assay (though titers are low or absent in isolated cysts), or histopathology. The Dowling Orlando technique is the most effective surgical method for the removal of cerebral hydrated cysts with minimal risk of rupture.[2] In this technique, the head is placed lower than the level of the operation table and the craniotomy flap is opened according to the size and site of the lesion. The surgical field must be cleaned with scolicidal solution (warm 3% normal saline solution) to prevent recurrence because even a minimal spillage can lead to new cysts formation, i.e. 1 mL of cyst fluid contains 4,000,000 scolices. Concurrent high-dose glucocorticoids minimize the inflammatory response. Presurgical administration of benzimidazoles such as Albendazole or Mebendazole reduces the rate of recurrence, and the medication should continue for 6 months.
