Aims and objectives
Metastases represent the most frequent brain neoplastic lesions in the adult population.
Calcified brain metastases (CBM) are reported to be rare and to be found predominantly in patients treated with radiotherapy (RT).
Nevertheless CBM may be present ab initio and must be differentiated from other calcified lesions.
The primary tumors reported to be responsible for CBM are squamous cell carcinoma of the lung,
adenocarcinoma of the lung,
breast adenocarcinoma,
sarcoma of the mediastinum,
squamous cell carcinoma of the cervix,
adenocarcinoma of the pancreas,
non-Hodgkin’s lymphoma,
osteosarcoma and mucinous colorectal and ovarian adenocarcinomas (1,2).
Intraparenchimal brain calcifications can be found in a variety of lesions including endocrine/metabolic,
infectious and primary neoplastic etiologies,
but CBM should also be considered in the differential diagnosis.
