Insights
L2-hydroxyglutaric aciduria (L2HGA) is a rare condition causing neurologic issues. This case report details its key MRI findings and their evolution over time, aiding diagnosis.
Area of Science:
- Neurology
- Pediatric Radiology
- Metabolic Disorders
Background:
- L2-hydroxyglutaric aciduria (L2HGA) is a rare inherited metabolic disorder.
- It presents with significant neurological impairments, including developmental delay, cognitive deficits, and behavioral issues.
Observation:
- A 15-year-old patient with undiagnosed neurological problems underwent serial MRI scans.
- Initial clinical presentation was nonspecific, necessitating further diagnostic investigation.
- Organic acid testing confirmed the diagnosis of L2HGA.
Findings:
- Serial MRI scans revealed characteristic and evolving imaging features of L2HGA.
- Key radiological findings, when recognized, can aid in diagnosing L2HGA.
- The progression of imaging abnormalities correlated with disease advancement.
Implications:
- Radiologists play a crucial role in identifying L2HGA through characteristic MRI findings.
- Early recognition of radiological signs can expedite diagnosis in children with nonspecific neurological symptoms.
- Understanding the temporal evolution of L2HGA imaging features improves patient management and diagnostic accuracy.
Abstract:
We report of a 15-year-old patient who initially presented to the specialist children's hospital with neurologic problems including developmental delay, behavioral difficulty and poor cognition. Upon organic acid testing, the patient received a diagnosis of L2-hydroxyglutaric aciduria (L2HGA). Serial MRI scans were performed throughout the patients childhood, demonstrating an evolution of imaging features as the disease progressed. A radiologist's recognition of the key findings associated with L2HGA can help prompt the diagnosis in cases of a nonspecific clinical presentation. This case report highlights the key radiological features associated with L2HGA, whilst illustrating how these changes may evolve and appear over the time course of a patient's journey.
