Is active Surveillance for Renal Neoplasms with Oncocytic Features Safe?
Although the majority of oncocytic renal neoplasms will grow with time, surveillance appears to remain safe. Patients opting for this strategy should be made aware that a diagnosis of oncocytoma following biopsy is associated with some degree of uncertainty due to the difficulty of differentiating them from other oncocytic renal neoplasms.
The volume of CSDH is not related to recurrence in patients undergoing burr-hole craniostomy with closed-system drainage. Layering of the haematoma was the only independent risk factor on CT images for recurrence of CSDH in our series.
