Introduction: Calcification in brain metastasis occurs rarely so it is reported in approximately 1% of surgical and 6.6% of autopsy specimens. Here we report a new case of brain metastasis with calcification.
Case presentation: A 44-year-old woman presented with a generalized tonic-clonic seizure with no neurological deficit on physical examination. Brain imaging demonstrated a hyperdense lesion on computed tomography scan and hyposignal and rim enhancement on T1, T2 and T1 with gadolinium injection sequence images in the right parieto-occipital lobe. Intraoperatively, there was a well-defined solid homogenous calcified mass within brain parenchyma. The lesion that resembled a meningioma was totally resected. The histopathological examination revealed metastatic adenocarcinoma.
Conclusion: Metastatic brain lesions should be in the differential diagnosis of a solitary calcified brain mass, although it occurs rarely. It is important to differentiate it radiologically from intralesional haemorrhage.
