Plain-English summary
A 4-year-old male Pomeranian was brought in after suddenly showing signs of serious neurological issues, like confusion or difficulty moving, without any known injury. The veterinarian performed an MRI and found a large area of bleeding in the brain, which was likely caused by a condition called necrotizing encephalitis (NE) that the dog had been suffering from for two years. Unfortunately, the dog's condition worsened over time, and while the exact cause of the bleeding is unclear, it seems that NE made the dog more prone to this type of injury.

Abstract
A 4-year-old castrated male Pomeranian dog with a 2-year history of necrotizing encephalitis (NE) presented for acute neurological deterioration without trauma. Magnetic resonance imaging (MRI) revealed a broad crescent-shaped lesion with mixed signal intensities on T1- and T2-weighted images, hypointense areas on T2* images, contrast enhancement in the outer membrane, and a mass-like lesion with fluid-fluid layers. The lesion was diagnosed as a chronic subdural hematoma secondary to spontaneous hemorrhage in a dog with NE. A direct causal relationship remains uncertain; however, NE could have contributed to the increased vulnerability of bridging veins. Serial MRI evaluations revealed progression of the lesion. This is the first report describing the MRI features of chronic subdural hematoma in a dog with NE.
