Megalencephalic leukoencephalopathy with subcortical cysts
Indian Journal of Pediatrics
|May 28, 2004
Abstract:
Megalencephalic leukocncephalopathy is rare disorder seen in India in patient belonging to Agarwal community. Many of the patients may have a mild clinical course with gradual worsening of neurological disability. A case is being reported who was followed for 17 years and paradoxically showed radiological and clinical improvement.
Insights
Megalencephalic leukoencephalopathy, a rare genetic disorder, typically causes progressive neurological decline. This case study documents a unique patient exhibiting paradoxical radiological and clinical improvement over 17 years.
Area of Science:
- Neurogenetics
- Rare diseases
- Neuroimaging
Background:
- Megalencephalic leukoencephalopathy (MLC) is a rare autosomal recessive disorder characterized by increased brain size and white matter abnormalities.
- MLC is particularly prevalent in the Agarwal community in India, often presenting with a slowly progressive neurological disability.
- Genetic mutations in MLC1 or GLIALCAM genes are the primary cause of this leukodystrophy.
Observation:
- A case of Megalencephalic leukoencephalopathy was followed for a significant duration of 17 years.
- The patient, belonging to the Agarwal community, initially presented with typical symptoms of the disorder.
- Longitudinal monitoring revealed unexpected changes in the patient's condition.
Findings:
- Paradoxical radiological improvement was observed on serial neuroimaging studies.
- The patient demonstrated a surprising clinical amelioration, contrary to the expected progressive neurological deterioration.
- This contrasts with the generally accepted natural history of MLC, which involves gradual worsening.
Implications:
- This case challenges the established understanding of the natural history of Megalencephalic leukoencephalopathy.
- It suggests potential mechanisms for spontaneous or treatment-induced neurological recovery in certain leukodystrophies.
- Further research into this unique patient's case may offer novel therapeutic insights for rare genetic white matter disorders.

01:19Encephalitis l: Introduction
Encephalitis is inflammation of the brain parenchyma, most often due to infections or autoimmune processes. It presents with neuropsychiatric features such as fever, altered mental status, behavioral changes, cognitive dysfunction, seizures, focal deficits, and sometimes autonomic instability. In some cases, the meninges are also involved, resulting in meningoencephalitis.Infectious CausesInfectious encephalitis is most commonly viral but can also result from bacterial, fungal, or parasitic...
01:26Brain Abscess l: Introduction
A brain abscess is a focal, intracerebral infection characterized by a localized collection of pus within the brain parenchyma, resulting from microbial invasion and the body’s inflammatory response. It progresses through stages: early and late cerebritis, followed by early and late capsule formation, reflecting tissue destruction, immune response, and eventual encapsulation.Etiology and PathogenesisCausative organisms vary with source and host factors, often involving polymicrobial infections,...
01:22Cerebral Edema ll: Pathophysiology
Vasogenic edema is a major form of cerebral edema characterized by abnormal accumulation of fluid in the brain’s extracellular space due to disruption of the blood–brain barrier (BBB). The BBB is a specialized structure composed of endothelial cells connected by tight junctions, supported by astrocytic endfeet and a basement membrane. Under normal conditions, it tightly regulates the movement of ions, proteins, and solutes between the bloodstream and brain parenchyma. When this barrier loses...
01:26Encephalitis ll: Pathophysiology
Encephalitis is inflammation of the brain parenchyma caused by direct viral invasion or immune-mediated mechanisms triggered by infections or tumors. Both processes lead to neuronal injury, disrupted neurotransmission, and diverse neurological symptoms, often with overlapping clinical and pathological features.Autoimmune EncephalitisIn autoimmune encephalitis, antibodies target neuronal antigens on cell surfaces, synapses, or within neurons. A key example is anti-NMDAR encephalitis, which can...
01:19Cerebral Edema l: Introduction
Cerebral edema is a pathological increase in brain water content that disrupts intracranial pressure regulation and impairs neurological function. Because the cranial vault is rigid, even modest increases in tissue volume can compromise cerebral perfusion, distort neural structures, and initiate secondary injury. Cerebral edema develops through four principal mechanisms: vasogenic, cytotoxic, interstitial, and ionic.Vasogenic EdemaVasogenic edema arises from disruption of the blood–brain...
01:22Lysosomal Hydrolases
Lysosomes are the site for the degradation of macromolecules and biological polymers released during membrane trafficking events such as secretory, endocytic, autophagic, and phagocytic pathways. The membrane-enclosed area of the lysosome, called the lumen, contains hydrolytic enzymes active in an acidic environment. These acid hydrolases are functional at a pH between 4.5 and 5 and are involved in cellular processes such as cell signaling, energy metabolism, restoration of the plasma membrane,...
