Plain-English summary
A 10-year-old domestic shorthair cat was diagnosed with a brain tumor called a tentorial meningioma and underwent surgery to remove it. The surgery was successful in completely removing the tumor in four out of six cats, but one cat died shortly after due to severe bleeding. After surgery, all cats experienced temporary worsening of their symptoms, but most improved over time, although two cats remained blind. Unfortunately, all five surviving cats eventually had to be euthanized due to tumor regrowth within a few months to two years after surgery.

Abstract
The surgical technique for removal of tentorial meningiomas is described on six cats using a unilateral temporal supracerebellar transtentorial approach. Complete gross tumour resection was achieved in four of six cats. In one cat, only subtotal resection was achieved. One cat died shortly after surgery because of extensive cerebral haemorrhage. The surgical approach, combined with cisternal or ventricular cerebrospinal fluid puncture and an open-window technique (tumour fenestration and enucleation) provided sufficient visibility and tumour accessibility without excessive manipulation of the brain parenchyma. In all patients, a postoperative transient worsening of the clinical signs was observed. The neurological signs resolved with time with the exception of blindness in two cats. All five surviving cats were monitored for a mean follow-up time of 19 months (median 20 months; range 6-30 months). All patients died or were euthanased because of tumour regrowth within the follow-up period. Although challenging, surgical treatment is a useful therapeutic measure in the treatment of cats presenting with tentorial meningiomas.
