Abstract
Objective: To report the diagnosis and clinical management of a case of suspected intracranial hypovolemia (IH) in a dog after resection of a large fronto‐olfactory chordoid meningioma. Study design: Clinical case report. Animal: One 8‐year‐old border collie with forebrain neurological signs caused by a fronto‐olfactory extra‐axial mass diagnosed by using MRI. Methods: The dog underwent bilateral transfrontal craniotomy for excision of the mass by using ultrasonic aspiration. Immediate postsurgical MRI revealed complete gross resection with no evidence of early‐onset complications such as edema, hemorrhage, mass effect, or pneumoencephalus. However, diffuse symmetric meningeal thickening and contrast enhancement were noted. No complications were noted during surgery or while under anesthesia. Results: Neurological deterioration was observed postoperatively. No abnormalities were detected systemically. Thus, early MRI‐confirmed findings and neurological deterioration were suspected to be caused by IH. Conservative treatment consisting of bed rest, gabapentin, and intravenous theophylline was then initiated in addition to steroids, antiepileptic drugs, and antibiotics. A gradual neurological improvement was observed, and the dog was discharged completely ambulatory with moderate proprioceptive ataxia 15 days after surgery. Conclusion: The clinical and MRI‐confirmed findings reported here are consistent with IH, a well‐described syndrome in man. This is the first report of a dog with MRI‐confirmed findings consistent with IH describing subsequent response to medical management. Clinical significance: Intracranial hypovolemia after craniotomy should be considered when there is neurological deterioration and characteristic MRI‐confirmed findings.
