AI Article Synopsis
- The study focused on analyzing the clinical and MRI characteristics of acute Marchiafava-Bignami disease (MBD) in 23 patients, categorizing them into two types based on the extent of callosal involvement.
- Type A patients demonstrated worse cognitive function and greater extracallosal issues, along with longer illness duration compared to Type B patients.
- Both types showed significant improvement in cognitive scores and complete resolution of lesions after treatment, indicating that while the initial severity varies, full recovery is achievable with appropriate therapy.
Article Abstract
We aimed to investigate the clinico-radiologic features of acute Marchiafava-Bignami disease (MBD) and its evolutionary process after effective treatment through subgroup comparison. The clinical and MRI data of 23 patients with acute MBD were retrospectively analyzed and divided into type A (12 cases, with entire callosal involvement) and type B (11 cases, with focal callosal involvement). The clinical assessments and MRI findings (before and after treatment) were compared between the two subtypes. Compared with type B, type A had lower MoCA (Montreal Cognitive Assessment) scores at admission (16.50 ± 1.73 vs 18.27 ± 1.68, P = 0.021) and were more common with extracallosal involvement (66.67% vs 18.18%, P = 0.036) and longer illness duration (18.3 ± 2.1 days vs 15.6 ± 2.4 days, P = 0.012). During the treatment, the residual lesion in the splenium was more common in type A (58.33% vs 9.09%, P = 0.027). After treatment, the MoCa scores of both subtypes gradually increased (P < 0.001), and the callosal and extracallasal lesions disappeared completely. Clinico-radiologic typing of acute MBD is related to the severity of early symptoms, but not to the prognosis. Complete clinico-radiologic recovery is possible for both subtypes with combined treatment. The clinico-radiologic reversibility is helpful for accurate diagnosis and therapeutic evaluation.

Marchiafava-Bignami disease (MBD) is a rare neurological disorder predominantly associated with chronic alcohol use, characterized by demyelination and necrosis of the corpus callosum. The condition often presents with cognitive dysfunction, motor deficits, and altered consciousness, which can range from mild confusion to severe stupor. Early recognition and treatment are crucial for improving outcomes.

Background: Marchiafava-Bignami disease (MBD) is an exceptionally rare condition, a fact that should pique the professional curiosity of medical practitioners. In recent years, case reports of this disease have been infrequent, and no comprehensive analysis or summary of the characteristics of the published cases has been conducted.
Methods: We collected the medical records of three patients treated at our hospital from March 2022 to March 2023.

Marchiafava-Bignami disease (MBD) is uncommon and typically linked with persistent alcohol consumption; nevertheless, instances have been reported in non-alcoholic individuals with nutritional deficiencies. Depending on the severity, this condition may manifest as acute, subacute, or chronic neurological signs and symptoms, ranging from moderate dysarthria or mild disorientation to coma and death. We report a case of a 30-year-old, 14-week pregnant female who presented with complaints of persistent vomiting and loss of appetite.
View Article and Find Full Text PDFBackground: Marchiafava-Bignami disease is a rare neurological disease characterized by acquired lesions of the corpus callosum. Although the major causative etiology is chronic alcoholism, a case caused by acute alcohol intoxication has not yet been reported.
Case Presentation: A 19-year-old female with no known medical history or a history of chronic alcohol consumption was brought to the emergency department in a coma after binge alcohol consumption.
Key Clinical Message: Marchiafava-Bignami disease, a rare condition often associated with alcoholism, shows myelin degeneration with tissue necrosis specifically in the corpus callosum. Urgent application of magnetic resonance imaging could lead to prompt diagnosis.
Abstract: A 66-year-old male with habitual alcohol drink complained acute deterioration of left-side muscle weakness as initial presentation.
