Formation of a meningoencephalocele after removal of a frontal lobe meningioma by transfrontal craniotomy in a cat


Günther, Christian; Beckmann, Katrin; Steffen, Frank (2020). Formation of a meningoencephalocele after removal of a frontal lobe meningioma by transfrontal craniotomy in a cat. Journal of feline medicine and surgery open reports, 6(2):205511692095719.

Abstract

A 10-year-old castrated male domestic shorthair cat was referred for surgical treatment of a left-sided frontal lobe meningioma diagnosed by CT. Clinically, the cat had generalised tonic–clonic seizures, which reduced in frequency after treatment was started with prednisolone. After definition of the anatomical landmarks of the feline skull, a bilateral transfrontal craniotomy allowed en bloc removal of the meningioma. While postoperative recovery was uneventful, right-sided proprioceptive deficits were still present 6 months after surgery. MRI detected a probable meningoencephalocele herniating through the surgical bone defect in the frontal sinus. Because of the mild neurological deficits and good quality of life, the meningoencephalocele was not treated. Thirty-one months after meningioma removal the cat was alive without further neurological progression.
