The huge congenital intracranial teratoma is very rare. We report a case of a 77 years old male with giant congenital brain teratoma without clinical symptoms. His computed tomography (CT) scan showed a massive tumor (6 × 5 × 6 cm) of irregular high density (inside with some point flaky low density) in left temporal lobe region, the lower corner of the left ventricle downward shift, and enhanced CT scan no enhancement. Magnetic resonance imaging (MRI) on brain showed an irregular huge tumor in the left temporal lobe area, with multiple nodular or lobulated mixd high and low or equal signal changes, in which the liquid signal based. The midline was shift to the right, and the posterior horn of the left ventricle was compressed and downward shift, expansion, and hydrocephalus. After follow-up 12 months, the pa-tient presents a normal daily life and work and no neurological signs as usual. Our observations show that the huge tu-mor in brain with multiple nodular or lobulated variety of mixed signal changes on MRI without symptoms is a con-genital intracranial silent teratoma
