Meningeal Metastasis Relapse With Focal Involvement of Cranial Bone Flap: A Case Resolved by 18F-DOPA PET/MRI

A 63-year-old woman was referred to our PET/MRI platform to evaluate the possible relapse of a meningeal metastasis, complicating an invasive ductal carcinoma of the left breast. This metastasis was diagnosed on a left hemiparesis and treated by surgery and radiation therapy. One year later, the same symptoms led to another brain MRI examination that found a contrast-enhanced lesion in the operating site. We decided to perform a 18F-DOPA PET/MRI to document this lesion, which confirmed the diagnosis of a probable relapse and revealed a focal uptake on the bone flap.
