A giant parapharyngeal space lipoma

Abstract

Parapharyngeal space (PPS) lipomas are incredibly uncommon. Prestyloid or poststyloid compartments are the only locations for PPS lipomas. Liposarcoma is a crucial differential to rule out. In order to treat PPS lipomas, the required radiological tests, including magnetic resonance imaging, a biopsy of the lesion if that is available, and lipoma removal surgery are all necessary. We intended to describe a unique giant PPS lipoma that affects both prestyloid and poststyloid compartments.

Keywords: Giant; Lipoma; Parapharyngeal space.

Fig. 1
(A) B-mode ultrasonography and (B) color-Doppler mode ultrasonography revealed a hypoechoic mass (arrow) with well-demarcated margin on the right submandibular region.

Fig. 2
Magnetic resonance imaging revealed that the mass (arrow) was hyperintense on (A) axial T1-weighted imaging and (B) coronal T2-weighted imaging but hypointense on (C) fat-suppressed T2-weighted imaging.

Fig. 3
Diffusion-weighted imaging revealed that the diffusivity of the mass (arrow) was restricted.

Fig. 4
Axial (A) and coronal (B) fat-suppressed T1-weighted imaging with contrast enhancement revealed that the mass (arrow) did not absorb contrast agent.
