RT Journal Article SR Electronic T1 Intracranial Leptomeningeal Carcinomatosis from Breast Cancer Detected on 18F-FDG PET JF Journal of Nuclear Medicine Technology JO J. Nucl. Med. Technol. FD Society of Nuclear Medicine SP 227 OP 228 DO 10.2967/jnmt.114.148791 VO 43 IS 3 A1 Bradley J. Carra A1 Michael N. Clemenshaw YR 2015 UL http://tech.snmjournals.org/content/43/3/227.abstract AB 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 18F-FDG PET/CT, despite its low sensitivity for detection of CNS metastases from non-CNS primary tumors.
