Abstract

A 5-month-old female domestic short-haired cat presented with a history of seizure episodes for two months following an animal bite injury to the head. There were no remarkable findings on physical and neurological examination or blood analysis. Computed tomography revealed a fracture of the left parietal bone with an inward displacement of the bone fragment while magnetic resonance imaging revealed an enlarged temporal horn of the left lateral ventricle and a pseudomeningocele compressing the adjacent cerebral parenchyma. Subsequently, cerebrospinal fluid analysis results were normal. The patient was diagnosed with traumatic brain injury (TBI), with subsequent post-traumatic hydrocephalus (PTH) and pseudomeningocele. Despite treatment with phenobarbital and levetiracetam, seizures were not sufficiently controlled. Craniectomy for bone fragment removal and duraplasty were performed after a week. The patient then returned to normal condition with no further seizure activity. On repeated MRI two months after discharge, the hydrocephalus of the lateral ventricle and pseudomeningocele were enlarged; however, the patient maintained a good clinical status without any neurological signs. To the best of our knowledge, PTH and intracranial pseudomeningoceles have not yet been reported in cats. PTH and pseudomeningocele are among the complications of TBI and may not have any significant relevance with the clinical signs in this case. Thus, to broaden our knowledge about PTH and pseudomeningocele in cats, we describe serial changes in the clinical findings of this cat over the treatment period.
