Nasopharyngeal Vascular Hamartoma in a Dog

Figure 1

Sagittal (a), dorsal (b), and axial (c) CT images in soft tissue window illustrating a soft tissue/fluid dense material (white arrows) in both ventral nasal passages, slightly more in the right side, beginning at the second maxillary premolars. At the caudal third of the hard palate, the nasopharynx becomes completely occluded by the mass structure (best seen on the axial view (c)). No destruction of the ethmoturbinates is identified, and the cribriform plate is intact. The sinuses are unaffected.
