Summary
This study reports a rare pineal cystic lesion with unusual imaging features. Histopathology revealed a cystic epithelial lining and a solid xanthogranuloma component.
Area of Science:
- Neuro-oncology
- Pathology
- Radiology
Background:
- Pineal cystic lesions are rare intracranial tumors.
- They can present with varied clinical and radiological manifestations.
Observation:
- A 64-year-old male presented with headache due to a large pineal cystic lesion.
- Unusual magnetic resonance imaging (MRI) findings included T1/T2 hyperintense cystic areas and T1 hypointense/T2 mixed solid nodules.
Findings:
- Surgical removal via a right occipital transtentorial approach was performed.
- Histopathology confirmed a bi-layered epithelial lining with squamous metaplasia in the cystic portion.
- The solid component exhibited xanthogranuloma characteristics, including cholesterol clefts and inflammatory cells.
Implications:
- This case highlights the importance of comprehensive histopathological analysis for diagnosing complex pineal region tumors.
- The unusual imaging findings underscore the need for careful radiological interpretation.
- Understanding the dual nature of these lesions aids in appropriate clinical management and prognosis.
