Imaging differentiation on extra-axial fluid collections: a clinical Image.

A 3 month – old male patient with a history of seizures presents to the Pediatric neurosurgery department with his parents, on initial evaluation a head circumference of 47.5 cm (> percentile 99 on the WHO chart) was seen. A brain MRI was performed and an extra axial fluid collections (Chron...
