This case study highlights a patient with neurofibromatosis type 2 (NF2) who developed significant neurological symptoms, including tumors and weakness, later in life. It underscores the variable presentation of NF2, often lacking early skin changes.

Area of Science:

  • Neurology
  • Oncology
  • Genetics

Background:

  • Neurofibromatosis type 2 (NF2) is a genetic disorder characterized by the development of tumors, primarily schwannomas and meningiomas.
  • The diagnosis of NF2 is typically based on clinical criteria, often involving bilateral vestibular schwannomas or a family history.
  • NF2 can present with a wide range of neurological symptoms due to tumor location and growth.

Observation:

  • A 24-year-old woman presented with long-standing peripheral facial nerve paresis, balance disturbance, hearing loss, and epileptic seizures.
  • Cerebral MRI revealed multiple large supra- and infratentorial tumors, histologically confirmed as bilateral acoustic schwannomas and mixed meningioma.
  • The patient was diagnosed with NF2. Later, she developed weakness in all extremities, with spinal MRI showing an intramedullary cervical tumor.

Findings:

  • Histopathological examination confirmed bilateral acoustic schwannomas and mixed meningioma, consistent with NF2 diagnosis.
  • The appearance of significant neurological deficits, including spinal cord involvement, occurred late in the disease course.
  • The patient experienced clinical improvement with dexamethasone treatment for the cervical lesion, avoiding surgical intervention.

Implications:

  • This case emphasizes that neurofibromatosis type 2 may present without typical neurocutaneous stigmata, challenging early diagnosis.
  • The late onset of severe neurological symptoms highlights the importance of long-term monitoring in NF2 patients.
  • The response to dexamethasone suggests a potential role for anti-inflammatory strategies in managing NF2-related spinal cord lesions.
