A 35-year-old man went to an outpatient clinic about a lump on the back of his head. It was growing, tender, and coming with worsening headaches. A skull X-ray showed a rounded lesion in the right parietal bone with a classic sunburst pattern, a finding that usually suggests a benign process.
The follow-up brain MRI is where the case turned. It picked up a second lesion he had no idea about: a dural-based mass on the midline of the posterior fossa, enhancing uniformly. That appearance strongly suggested a meningioma, the most common primary brain tumor.
