  Abstract 

Abscess of massetric region are frequently misdiagnosed as parotid abscess. Ultrasonography, particularly is of immense help to differentiate between these lesions. This case highlights the importance of ultrasonography in this particular context.

Keywords: Massetric abscess, parotid abscess, ultrasonography

A 28-year-old male patient reported with a painful unilateral swelling on the right side of the face. The swelling has been gradually enlarging in size since 1 week and was extremely painful. Despite taking medication, the swelling had not subsided. Patient also reported of fever since 1 week. Extraoral examination showed swelling of approximately 5 × 5 cm in size [Figure 1]. The swelling was firm and tender on palpation. Intraoral examination showed that the area over the Stensen duct was erythematous, and milking of the parotid gland showed no evidence of pus discharge and there was no expression of saliva [Figure 2]. Furthermore, restriction of mouth opening (trismus) and hyposalivation was present. Based on the clinical examination, diagnosis of Parotid abscess was arrived. Ultrasonography with high-frequency probe 10 MHz was performed. Ultrasonography revealed that both the parotid glands were normal. Hypoechoic heterogenous collections of size 3 × 3 × 1.5 cm were noticed in the right massetric muscle region [Figure 3]. Final diagnosis of right massetric abscess was arrived. The abscess was treated by incision and drainage of pus. Antibiotics and analgesics were prescribed.

Massetric abscess is relatively rare and is frequently confused with parotid abscess. [1] It should be noted that ultrasonography is a helpful diagnostic tool to differentiate the lesions of masseter from the inflammatory swellings of the facial region. [2] This case confirms this high diagnostic value of ultrasonography.
