Abstract

Purpose

Intracerebellar malignant nerve sheath tumor (ICMNST) is an extremely rare entity, only two cases have been reported previously, and this is the first case to be reported in a child. The histogenesis, diagnosis, and management of this entity are very ambiguous, and natural history in a child is unknown.

Methods

The authors report a 7-year-old girl who presented with ataxia and signs of raised intracranial pressure and discuss the challenges in diagnosis, surgical strategy, and treatment.

Results

Following gross total resection and radiation to tumor bed, the patient had unremarkable recovery and is recurrence free at 1-year follow-up.

Conclusion

ICMNSTs are extremely rare tumors of the cerebellum. Preoperative radiological diagnosis is not possible due to its close radiological resemblance to other common posterior fossa tumors. Immunohistochemistry plays a pivotal role in clinching the diagnosis. Though the reported adult counterparts have shown dismal prognosis, the pediatric counterparts may fare better with good surgical resection followed by radiotherapy.
