Paediatric Primary Pachymeningeal Xanthogranuloma with Scattered Foci Displaying Reticulohistiocytoma-like Features.

We report a unique case of a 4-year-old girl with an intriguing fibrohistiocytic tumour. Magnetic resonance imaging scans showed a dural mass of variegated intensity compressing the left occipital pole and apparently extending toward the superior sagittal sinus. Grossly, the cut surface of the surgical specimen was yellow, pale, and soft with reddish kernel-like crusts.

Stereotactic biopsy for brainstem tumors in pediatric patients.

Objective: Our aim is to describe clinical and paraclinical features in patients who underwent stereotactic-guided biopsy for brainstem tumors.

Methods: A study of case series was made by reviewing the records of patients who underwent stereotactic biopsy for brainstem tumors.

Results: Stereotactic biopsy for brainstem tumors was performed (between 2000 and 2008) in 20 children (11 girls, and 9 boys), mean age 7.
