Abstract:
This 11-year-old boy presented with a rare case of Castleman syndrome caused by a clear cell meningioma manifesting as persistent fever of unknown origin, 2 years after glomerulonephritis. Laboratory investigation of the patient showed an increased inflammatory reaction, as well as elevated polyclonal gamma globulin titer and serum level of C-reactive protein. Magnetic resonance imaging revealed a tumor at the cerebellopontine angle. Neurosurgical intervention was performed under the presumptive diagnosis of Castleman syndrome caused by intracranial tumor. Histological examination of the tumor verified that it was clear cell meningioma with infiltration of lymphoplasma cells, and surgical removal resulted in complete resolution of the patient's symptoms and biochemical abnormalities. The present case of clear cell meningioma manifesting as Castleman syndrome shows that the possibility of a brain tumor should be considered in patients presenting with fever of unknown origin, anemia, hypergammaglobulinemia, or other systemic illness.
Insights
A rare case of Castleman syndrome in an 11-year-old boy was caused by a clear cell meningioma. Surgical removal of the brain tumor resolved symptoms, highlighting the need to consider intracranial tumors in unexplained systemic illnesses.
Area of Science:
- Neurology
- Oncology
- Pathology
Background:
- Castleman syndrome is a rare lymphoproliferative disorder.
- Intracranial tumors can present with diverse systemic symptoms.
- Fever of unknown origin requires comprehensive differential diagnosis.
Observation:
- An 11-year-old boy presented with persistent fever of unknown origin and symptoms consistent with Castleman syndrome.
- Laboratory findings revealed elevated inflammatory markers, polyclonal hypergammaglobulinemia, and C-reactive protein.
- Magnetic resonance imaging identified a cerebellopontine angle tumor.
Findings:
- Histological examination confirmed the tumor as a clear cell meningioma with lymphoplasma cell infiltration.
- Neurosurgical intervention involved the presumptive diagnosis of Castleman syndrome secondary to an intracranial tumor.
- Complete resolution of systemic symptoms and biochemical abnormalities was achieved post-surgical tumor resection.
Implications:
- This case highlights a rare association between clear cell meningioma and Castleman syndrome.
- Intracranial tumors should be considered in the differential diagnosis of unexplained fever, anemia, and hypergammaglobulinemia.
- Early diagnosis and surgical management of such tumors can lead to favorable outcomes.
