Plain-English summary
A 6-year-old domestic short-haired cat suddenly showed signs of neurological issues, specifically right-sided brain problems. An MRI taken four days later revealed a large lesion in the right frontal sinus that was pressing on the brain, indicating it was a giant hemorrhagic mucocele (a fluid-filled cyst with bleeding). This condition is rare in cats, and the MRI findings helped confirm the diagnosis. While the abstract does not specify treatment or outcome, early detection through imaging is crucial for managing such cases effectively.

Abstract
A 6-year-old domestic short-haired cat was presented with an acute onset of right cortical encephalopathy. Magnetic resonance imaging (MRI) performed 4 days after the onset of clinical signs revealed a lesion originating from the right frontal sinus with intracranial extension and compression of the right frontal lobe. The lesion was T1-weighted hypointense and T2-weighted and fluid-attenuated inversion recovery hyperintense. Signal voids within the lesion were observed on T2* images, consistent with hemorrhage. Peripheral ring enhancement was visible on postcontrast sequences. These features were consistent with a giant hemorrhagic mucocele. To the authors' knowledge, this is the first report of MRI characteristics of this lesion in a cat.
