A young man presented with 2-month history of headache and multiple seizure episodes. His neurological examination was unremarkable. CT and MRI revealed a spherical, well-circumscribed, smooth thin-walled, non-enhancing, intra-axial cystic lesion surfacing over the right cerebellum (figure 1A–C). There was no perilesional oedema and the fluid intensity (T1, hypointense; T2, hyperintense) was similar to that of cerebrospinal fluid. The typical imaging suggested a hydatid cyst. His serum tested negative for hydatid disease.
