Case Study
The article describes three cases of canine polycystic meningiomas. A female Labrador and two castrated male golden retrievers were assessed for having seizures, circling, and behavior changes. Extra-axial, contrast-enhancing, multiloculated, fluid-filled, cyst-like lesions with a mass effect were discovered through MRI. Differential diagnoses included cystic neoplasm, abscess or other infectious cyst, or fluid-filled anomaly. Surgical biopsy and postmortem histology were conducted.

    A 9-month-old, female Labrador retriever mix was presented for two types of seizure-like episodes, one of which occurred only during sleep. The two types of episodes were morphologically distinct. An electroencephalogram (EEG) demonstrated that the sleep-associated episodes occurred during rapid...

Due in large part to their scarcity, malignant meningiomas have been understudied and therefore represent an area where significant clinical...
