ALCL is characterized by CD30-positive cells and subclassified by anaplastic lymphoma kinase reactivity (ALK positive [ALK+] or negative [ALK−] cytogenics). Only 13 patients with ALCL have been reported with spread to the CNS. Of these, only one demonstrated pure leptomeningeal involvement with nonspecified ALK status. The following case report details the first instance of ALK+ ALCL with pure leptomeningeal spread. …
