Cerebral nocardia masquerading as metastatic CNS disease in an endometrial cancer patient.

Nocardia is a bacterial infection primarily originating from organic rich soil, endemic to several international geographic locations. We present the case of a 61-year-old woman previously treated for endometrial carcinoma, who three years later developed metastatic pulmonary disease and received systemic chemotherapy. After five months, she developed a large right posterior lobe lesion, suspicious for metastatic CNS disease. However, following neurosurgical resection of the lesion and infectious disease consultation, a diagnosis of nocardia was made.
