Abstract
BACKGROUND: Clival metastases of adenocarcinomas are exceptionally rare tumors, especially when they arise from the small intestine. To our knowledge, here we present first report of a metastasis of a duodenal adenocarcinoma to the clivus. We also present a systematic review detailing metastasis to the clivus.
METHODS: Studies were identified using the search terms clivus metastasis, skull base metastasis, and clivus in PubMed. We collected the following information: histopathology of the primary tumor, symptoms, history, treatment, and follow up.
RESULTS: A comprehensive review of the literature yielded 56 cases. Patients developed the first symptoms of clivus metastasis at a mean age of 58 years. The most common primary neoplasms originated from the prostate, kidney, or liver. Most patients presented with an isolated 6(th) nerve palsy or diplopia. The time interval from diagnosis of the primary tumor to symptomatic presentation of clivus metastasis ranged from 2 months to 33 years. 16 patients initially presented with symptoms of clivus metastasis without a previously diagnosed primary tumor. Survival data were available for 35 patients, of which 63% died within a range of 2 days to 31 months after initial presentation.
CONCLUSION: Most primary neoplasms originated from the prostate, kidney, and liver, which differ from previous reports on skull base metastases. Abducens nerve palsy is often the first presentation of clival metastasis. Clival metastasis from duodenal carcinoma, though very rare, should be considered in the differential diagnosis of bony lesions of the clivus in a patient with a history of duodenal adenocarcinoma.
