    Juvenile myasthenia gravis can present with thymic hyperplasia, showing interval thymic enlargement on CT scans. This thymic enlargement correlated with worsening clinical symptoms in this case.

    Area of Science:

    • Pediatric Neurology
    • Thoracic Imaging
    • Immunology

    Background:

    • Myasthenia gravis (MG) is an autoimmune disorder affecting neuromuscular junctions.
    • Juvenile myasthenia gravis (JMG) is a rare form of MG occurring in children and adolescents.
    • Thymic abnormalities, including hyperplasia and thymoma, are frequently associated with MG.

    Purpose of the Study:

    • To describe a case of thymic hyperplasia in a patient with juvenile myasthenia gravis.
    • To highlight the utility of serial computed tomography (CT) scans in monitoring thymic changes in JMG.
    • To correlate imaging findings with clinical disease activity.

    Main Methods:

    • A case report of a patient diagnosed with juvenile myasthenia gravis.
    • Serial CT scans of the chest were performed to evaluate thymic size and morphology.

  • Clinical assessments were conducted to monitor disease severity and progression.

    • Main Results:

    • The patient exhibited thymic hyperplasia, characterized by interval thymic enlargement on serial CT scans.
    • The observed thymic enlargement on imaging correlated with periods of clinical worsening of myasthenia gravis symptoms.
    • CT imaging provided valuable insights into the dynamic changes of the thymus in JMG.

    Conclusions:

    • Thymic hyperplasia can manifest as interval thymic enlargement in juvenile myasthenia gravis.
    • Serial CT imaging is a useful tool for monitoring thymic changes and their correlation with clinical status in JMG.
    • These findings underscore the importance of evaluating the thymus in pediatric patients with myasthenia gravis.
