Inquiry Details
References:
WHO Class CNS Tumors, 226. Familial tumour syndromes involving the nervous system
Question:
Reportability--Brain and CNS: Is "Lhermitte-Duclos disease" is reportable? See discussion.
Discussion:
The MRI states "Lhermitte-Duclos disease" but does not include "dysplastic gangliocytoma of cerebellum"; is this the same as "Lhermitte-Duclos dysplastic gangliocytoma of cerebellum (C716)"?
Answer:
"Lhermitte-Duclos disease" alone can be interpreted as "Lhermitte-Duclos dysplastic gangliocytoma of cerebellum (C716)" and reportable. The WHO classification for CNS tumors lists this entity as "Dysplastic gangliocytoma of the cerebellum (Lhermitte-Duclos disease)" signifying that the terms are used synonymously.
