Abstract: A 38-year-old man was admitted to our hospital with abdominal pain caused by acute pancreatitis. He had a history of alcohol abuse for over 10 years, consuming 1000 mL–1500 mL of 38% alcohol per day. Upon admission, he developed delirium, presenting with phobic hallucinations, dysphoria, and epileptic seizures. After 1 week, he exhibited an apathetic facial expression, poor mobility, reduced strength in his limbs. Physical examination revealed an indifferent expression, unclear speech, poor memory, calculation ability, and reflex responses. Strength in both upper limbs was graded at Grade I, while strength in the lower limbs ranged from Grade II to III. A brain CT and MRI showed swelling in the splenium of the corpus callosum, as well as in the bilateral frontal cortex and other cortical regions [Figure 1]. Marchiafava-Bignami disease (MBD) is an encephalopathy syndrome closely associated with chronic alcoholism.[1] It is mainly characterized by central demyelination and degenerative changes in the corpus callosum.[1] Clinically, it is often manifested by altered consciousness, cognitive impairment, and mental and behavioral disorders, including confusion, delirium, disorientation, and even coma.[2] Other symptoms may include ataxia, dysarthria, epilepsy, blurred vision, hearing loss, and urinary and fecal incontinence.[2] MBD can present with cerebral connection/disconnection syndrome, gaze palsy, pyramidal signs, myotonia, and other neurological signs.[2] Typical imaging findings include hyperintense signals in the midline, with significant rim enhancement and peripheral edema.[3] Lesions may also occur in the prefrontal and temporal lobes.[3] Patients with MBD are mainly treated with high-dose vitamin B (especially vitamin B1) and μ-opioid receptor antagonists to help manage alcohol withdrawal.[1]Figure 1: Brain imaging changes in patients with MBD.
