[Calcified cerebral metastasis]

Area of Science:

• Neurology
• Radiology
• Oncology

Background:

• Hyperdense lesions on cerebral computed tomography (CT) typically indicate acute hematoma.
• Focal brain calcifications are often linked to granulomas or tumors.
• Cerebral metastases are the most frequent intracranial neoplasms, but calcification is rare (approx. 1%).

Observation:

• A case involving a completely calcified cerebral metastasis was studied.
• Imaging modalities used included CT and magnetic resonance imaging (MRI).
• Initial CT interpretation suggested acute hemorrhage.

Findings:

• The lesion was a fully calcified cerebral metastasis.
• CT and MRI findings were analyzed.
• The initial interpretation of acute hemorrhage was re-evaluated.

Implications:

• This case underscores the need to consider metastatic causes for hyperdense brain lesions, even when calcified.
• Extensive calcification is an atypical feature for cerebral metastases, challenging initial diagnoses.
• Advanced imaging (CT/MRI) is crucial for differentiating metastatic lesions from other intracranial pathologies.
