This patient had a known diagnosis of breast cancer. The CT scan showed multiple sclerotic bone lesions on skull (metastatic). CT and MRI images demonstrated multiple cystic nodules randomly dispersed on brain parenchyma.
Cystic brain lesions could be misdiagnosed as abscesses, primary cerebral tumours, or parasitic infections (neurocysticercosis, which is endemic in the place where the patient came from).
On this case, the MRI images associated with other clinical findings allow the inference of breast cancer metastasis diagnosis (not pathologically proven).
