MRI findings are the enhancement of wall and scolex with surrounding edema which is consistent with the colloidal stage of neurocysticercosis. This case shows the cyst with dot sign, which is characteristic of the colloidal stage of neurocysticercosis.

Isolated neurocysticercosis can be atypical and not always easy to make a correct diagnosis because typical findings for neurocysticercosis are multiple lesions at multiple stages.

Differentials for an isolated lesion are tuberculoma or solitary metastasis. Hence the reason why this patient underwent a thorax CT to look for a primary tumor or pulmonary tuberculosis.
