OBJECTIVE
Gangliogliomas (GGs) are rare central nervous system tumors occurring primarily in the supratentorial compartment with infratentorial instances most often involving the brain stem. Infratentorial GGs typically present with signs and symptoms of increased intracranial pressure (ICP), cranial nerve deficits, or focal cerebellar findings; rarely, these tumors have been associated with focal seizures.
METHODS
In this report, we describe an atypical presentation of a cerebellar GG in a 20-month-old male who initially presented with syncope and emesis in the absence of electrographic evidence of seizures, radiographic evidence of hydrocephalus, or elevated ICP. The epidemiology, radiographic, and pathological findings as well as the treatment of these tumors are also discussed.
RESULTS
After gross total resection, the patient experienced full resolution of all his preoperative symptoms without the development of new neurological deficits.
CONCLUSIONS
Unlike their supratentorial counterparts, infratentorial GGs do not commonly present with seizures although rare reports exist in the literature of seizures attributed to cerebellar GG. Moreover, cerebellar GGs may produce nonspecific symptoms in the absence of concrete diagnostic findings. Such a presentation should prompt further neurological evaluation. Most cases of isolated cerebellar GG can be successfully treated with surgical resection and carry a favorable prognosis.
