Summary
A 45-year-old man had an expansile lesion in his parietal bones. Imaging suggested cancer, but histology confirmed a benign chronic diploic hematoma.
Area of Science:
- Neurosurgery
- Radiology
- Pathology
Background:
- Expansile lesions of the skull present diagnostic challenges.
- Distinguishing benign from malignant bone lesions is critical for patient management.
Observation:
- A 45-year-old male presented with an expansile lesion of the parietal bones.
- Advanced imaging, including CT, MRI, and digital subtraction angiography, was performed.
Findings:
- Radiological imaging findings were highly suggestive of a malignant neoplasm.
- Histopathological examination ultimately revealed a chronic diploic hematoma, a benign condition.
Implications:
- This case highlights the importance of integrating imaging findings with histopathology for accurate diagnosis.
- It underscores the potential for benign conditions to mimic aggressive neoplasms radiologically.
