Small cell lung cancer elevates procalcitonin levels in the absence of infection

A 77-year-old man with a history of hypertension, type 2-diabetes and chronic obstructive pulmonary disease came to the Emergency Department of our hospital with visual impairment, agraphia and memory loss. Cranial computed tomography (CT) revealed a hypodense lesion in the left posterior parietal white matter (maximum diameter of 4.5  cm) with vasogenic oedema. He was admitted to hospital to complete study of the primary neoplasm for suspicion of brain metastases. On day 3 post-admission, brain magnetic resonance imaging showed three images that suggested brain metastases.
