title: Intracranial Leptomeningeal Carcinomatosis from Breast Cancer Detected on 18F-FDG PET.
abstract: Leptomeningeal carcinomatosis is an uncommon manifestation of non-central nervous system (CNS) metastatic disease. Diagnosis, however, has important prognostic and treatment implications. We present a case in which intracranial leptomeningeal carcinomatosis from a primary breast cancer was detected with (18)F-FDG PET/CT, despite its low sensitivity for detection of CNS metastases from non-CNS primary tumors.
