新生児口腔内腫瘤の鑑別診断におけるMRIの有用性

Abstract

We describe the usefulness of magnetic resonance imaging (MRI) for differential diagnosis of intraoral tumor in neonates. We present two neonates who suffered from dyspnea due to intraoral tumor since bith. In both cases, computed tomogra- phy (CT) failed to reveal the communication between the intraoral tumor and intracranial organs. In Case 1, the intraoral tumor communicating with sella turcica through a cranio- pharyngeal canal was identified by MRI and then, a diagnosis of transsphenoidal meningoencephalocele was established. In Case 2, a diagnosis of solitary cyst in the oropharynx was established by MRI. MRI was very useful in the differential diagnosis of intraoral tumor in neonates.
