Calcified Brain Metastasis

Abstract

Two patients with rare cases of calcified brain metastases are reported. The relatively benign clinical course and prolonged survival are stressed. The first patient had an adenocarcinoma of unknown origin with three calcified brain metastases. The patient underwent an incisional brain biopsy without radiotherapy and survived for 2 years and 9 months. The second patient had a squamous cell carcinoma of the lung with a large, solitary brain metastasis. The brain tumor was calcified and remained stable without progression for at least 4 months before surgical resection.
