Gangliocytoma is an uncommon low-grade neuroepithelial tumour arising in the cerebral hemispheres, with medulla oblongata being extremely rare site of occurrence. We report a case of an 8-year-old female with recurrent vomiting, hypertension and left hemifacial spasms with a dorsally exophytic lesion arising from the medulla projecting into the fourth ventricle. She underwent excision of the lesion with intra operative cranial nerve monitoring guidance. Histopathology revealed clusters of large mature ganglion cells which were labelled by synaptophysin and CD34. Extreme rarity in this location makes clinical diagnosis and management of gangliocytoma challenging, although prompt diagnosis and total excision has a successful outcome. There are only six previous reports of gangliocytoma in the medulla oblongata.

UI	MeSH Term	Description	Entries
D008279	Magnetic Resonance Imaging	Non-invasive method of demonstrating internal anatomy based on the principle that atomic nuclei in a strong magnetic field absorb pulses of radiofrequency energy and emit them as radiowaves which can be reconstructed into computerized images. The concept includes proton spin tomographic techniques.

D008526	Medulla Oblongata	The lower portion of the BRAIN STEM. It is inferior to the PONS and anterior to the CEREBELLUM. Medulla oblongata serves as a relay station between the brain and the spinal cord, and contains centers for regulating respiratory, vasomotor, cardiac, and reflex activities.

D002648	Child	A person 6 to 12 years of age. An individual 2 to 5 years old is CHILD, PRESCHOOL.	Children

D005729	Ganglioneuroma	A benign neoplasm that usually arises from the sympathetic trunk in the mediastinum. Histologic features include spindle cell proliferation (resembling a neurofibroma) and the presence of large ganglion cells. The tumor may present clinically with HORNER SYNDROME or diarrhea due to ectopic production of vasoactive intestinal peptide.

D019569	Hemifacial Spasm	Recurrent clonic contraction of facial muscles, restricted to one side. It may occur as a manifestation of compressive lesions involving the seventh cranial nerve (FACIAL NERVE DISEASES), during recovery from BELL PALSY, or in association with other disorders.

D020546	Fourth Ventricle	An irregularly shaped cavity in the RHOMBENCEPHALON, located between the MEDULLA OBLONGATA; the PONS; and the isthmus in front, and the CEREBELLUM behind. It is continuous with the central canal of the cord below and with the CEREBRAL AQUEDUCT above, and through its lateral and median apertures it communicates with the SUBARACHNOID SPACE.	4th Ventricle,Quarto Ventricolo,4th Ventricles,Fourth Ventricles,Quarto Ventricolos,Ventricle, 4th,Ventricle, Fourth,Ventricles, 4th,Ventricles, Fourth,Ventricolo, Quarto,Ventricolos, Quarto
