Not everything is what it seems

We report a case of a 36-year-old man, with previous medical history of marihuana consumption, high blood pressure and asthma. He came to the emergency room with a 4-month history of altered behaviour and a fall from his own height. After conducting complementary tests, diagnoses were acute renal failure secondary to rhabdomyolysis and brain space occupying lesions (SOLs) under study. Initial suspicion of brain metastasis radically changed with the results of brain magnetic resonance imaging and thoraco-abdomino-pelvic computed tomography. This lead us to focusing on inflammatory-granulomatous aetiology, with our first option being neurosarcoidosis, later confirmed by the histological results of an adenopathic biopsy performed by fiberoptic bronchoscopy.
