title: [Leptomeningeal dissemination in an intestinal-type sinonasal adenocarcinoma: an uncommon presentation].
abstract: We present the case of a patient with a 30-year history of exposure to sawdust who was diagnosed with mucinous intestinal-type sinonasal adenocarcinoma after histological examination. The patient presented with neurological symptoms; moreover, intra- and extra-cranial leptomeningeal involvement, which is exceedingly rare in this type of tumors, was observed at the time of diagnosis.
