MRI and CT scan findings in the brain of a sheep with coenurosis

Abstract Coenurosis, caused by the larval stage of Taenia multiceps , leads to significant neurological impairment and economic losses in sheep. This report describes a 4‐month‐old ram presenting with ataxia, circling and head tilt. Magnetic resonance imaging and computed tomography imaging revealed multiple intracranial cystic lesions occupying 44% of the brain volume. Magnetic resonance imaging showed T2‐hyperintense and T1‐hypointense structures, while computed tomography identified corresponding hypodense areas. Hounsfield unit analysis confirmed the cystic nature of the lesions. Postmortem examination validated the imaging results, identifying Coenurus cerebralis cysts. These findings underscore the value of advanced imaging in diagnosing coenurosis, allowing accurate assessment of cyst location, size and number. Early radiological detection aids in prognosis, improves disease management, and may limit irreversible neurological damage. This case supports the integration of magnetic resonance imaging and computed tomography into diagnostic protocols for small ruminants with neurological signs. It contributes to ongoing efforts to enhance animal welfare and control potential zoonotic risks.
