Morbid obesity is a curable systemic disease that can cause several complications, including hypertension, diabetes mellitus, and osteoarthritis. However, it is not easy to control solely by conservative management. Bariatric surgeries, such as sleeve gastrectomy and gastric banding, are recently developed treatments that are applied to patients with morbid obesity in Korea. However, gastric surgery can cause surgical or metabolic complications, such as thiamine deficiency, which can lead to Wernicke's encephalopathy. This metabolic complication presents with typical symptoms of confusion, ophthalmoplegia, nystagmus, and ataxia. In this case report, we present a case of Wernicke's encephalopathy, which developed slowly following sleeve gastrectomy in a patient with morbid obesity.

A 24-year-old female blue and gold macaw (Ara ararauna) was presented for an acute onset of left head tilt. On examination, the macaw was dehydrated and had a 120-degree left head tilt, decreased proprioception of the left pelvic limb, and intermittent vertical nystagmus. Results of hematologic testing and biochemical analysis revealed severe leukocytosis with lymphopenia and heterophilia and a high uric acid concentration. Radiographs showed bilateral intertarsal joint osteoarthritis and a healed ulnar fracture. Magnetic resonance imaging of the brain revealed focal T2 and fluid-attenuated inversion recovery hyperintense lesions in the right cerebral hemisphere and in the midbrain. The midbrain lesion showed susceptibility artifact on the T2* sequence, suggesting hemorrhage. In the T2* sequence, iron accumulation (as seen with hemorrhage) distorts the magnetic signal, resulting in the production of a susceptibility artifact, which can then be visualized as a region of hypointensity. The bird was hospitalized but died despite intensive care. Necropsy revealed multiple cerebral vascular lesions including an acute cerebral infarct, a ruptured midbrain aneurysm, and multifocal systemic atherosclerosis. To our knowledge, this is the first report of a cerebral aneurysm in a bird. This report correlates the clinical presentation, imaging, and histopathologic findings in a macaw with central vestibular disease and demonstrates how advanced imaging techniques can identify hemorrhagic lesions through the T2* sequence.
