Surveillance for metastatic hemangiopericytoma-solitary fibrous tumors-systematic literature review on incidence, predictors and diagnosis of extra-cranial disease.

Background: Intracranial hemangiopericytomas (HPC) and solitary fibrous tumors (SFTs) (HPC-SFT) are rare vascular tumors that resemble meningioma on imaging and predominantly affect young adults. HPC-SFT have a high rate of local recurrence with well-known propensity for extracranial metastases. This provides clinical dilemmas frequently encountered in oncology: (i) How should these patients be monitored long term? (ii) Which primary tumors are more likely to metastasize?

Objectives: This systematic review aims to identify the incidence, common locations and time to presentation of extra-cranial metastases of HPC-SFT.

Patient-reported nasal morbidity following endoscopic endonasal skull base surgery.

Objective: To quantify the frequency and severity of nasal morbidity following endoscopic endonasal skull base surgery using patient-reported outcome measures.

Methods: Retrospective review and follow-up of all patients who underwent endoscopic endonasal skull base surgery at University Hospital Southampton between January 2007 and December 2011. Demographic data were collated from case notes and patients were asked a standardised questionnaire by telephone interview.
