ABSTRACT
The authors describe a case of a 47-year-old male smoker with a 3-month history of hearing loss, tinnitus and dizziness. Physical examination revealed neurosensory hearing loss. Small rounded hypodensities without mass effect were evident in a computed tomography scan of the head, confirmed by brain magnetic resonance imaging as multiple cystic lesions in both cerebral and cerebellar hemispheres, without perilesional edema or gadolinium enhancement, suggestive of neurocysticercosis. Extraparenchymal involvement was also noted. Albendazole and dexamethasone were started. As a chest radiograph showed a bilateral reticulonodular pattern, a bronchoscopy was performed showing normal results. However, transbronchial biopsy revealed lung adenocarcinoma. Thoracoabdominopelvic computed tomography scan showed secondary lung and bone lesions. Since brain lesions were not suggestive of secondary tumor lesions, a brain biopsy was performed confirming metastatic disease. This case illustrates some peculiar imagiological features of brain metastases in lung cancer, indicating that sometimes invasive procedures are required to establish a definitive diagnosis.
