Suggestive value of predilection site and imaging features of pediatric brainstem ganglioglioma including a case report.

Brainstem ganglioglioma is rarely reported. Due to its low incidence and atypical site, a brainstem ganglioglioma could easily be misdiagnosed as occurs with other pathological neoplasms radiologically. Here, we report an 8-year-old girl with a brainstem tumor confirmed as a ganglioglioma based on postoperative pathology results. We suggest that when a tumor located in the lower brainstem with benign radiological characteristics occurs in a child with a long-term history, the possibility of brainstem ganglioglioma should be considered in the preoperative diagnosis in addition to other low-grade neoplasms. Early stage diagnosis of brainstem ganglioglioma based on the clinical and imaging features is valuable for clinicians in order to perform effective treatment and achieve a good prognosis.
