Unusual central nervous system presentation of ALK-positive anaplastic large cell lymphoma in a child

摘要

An 11-year-old boy landed in emergency in a semiconscious state with a history of headache, generalised tonic-clonic seizures and vomiting of 6 months duration. On examination there was no lymphadenopathy or organomegaly. Contrast-enhanced computed tomography (CECT) scan revealed multiple dural based homogenously enhancing lesions along the left side of cavernous sinus, left tentorium, right tentorial edge, and left posterior temporal convexity dura with significant oedema in left tempro-occipital brain [Figure la-c].
