GCRG of the nasal cavity in a 7-year old girl with recent onset diplopia, epiphora, and rhinorrhea.

A, Axial noncontrast CT scan demonstrates a heterogeneous soft tissue mass with fluid-fluid levels centered at the inferior turbinate extending from the nares to the choanae. There is medial displacement of the nasal septum and lateral displacement of the medial wall of the maxillary sinus without cortical destruction.

B, Coronal T1-weighted MR image demonstrates a heterogeneous but predominately low T1 signal intensity with internal septa.

C, Axial T2-weighted MR image demonstrates fluid-fluid levels in a heterogeneous mass with surrounding nasal mucosal edema.

D, Coronal T2-weighted MR image again demonstrates cystic areas within the well-circumscribed heterogeneous nasal cavity mass.

E, Contrast-enhanced axial T1-weighted MR image demonstrates peripheral, septal, and soft tissue component enhancement.
