- AB The purpose of this report is to examine the computed tomography scans,
- magnetic resonance images, and pathologic findings in 44 patients, 42 of
- whom had inclusion-type cysts of the parotid and parapharyngeal space of
- varying etiologies. Two additional cases of cystic changes in the benign
- lymphoepithelial lesion (BLEL) of Sjogren's syndrome are highlighted
- here, since they had unusually large cystic components mimicking
- acquired immunodeficiency syndrome-related parotid cysts (ARPCs). A
- retrospective examination identified 18 ARPCs, 3 lymphoepithelial cysts
- (LECs), 13 cystic Warthin's tumors, 8 branchial cysts, and 2 cases of
- cysts in patients with Sjogren's syndrome (BLEL), all of whom had
- imaging studies and pathologic confirmation. There were 30 men and 14
- women with an age range of 25 to 72 years (median, 46.82 years). Any
- similarities in the imaging appearances were noted, as were any
- differences in pathologic detail. On imaging, only the cystic Warthin's
- tumors had any focal wall nodularity; the other cysts had smooth walls.
- When multiple parotid cysts were present, the distinguishing feature
- between ARPCs and cysts in BLEL (and some cystic Warthin's tumors) was
- the presence of diffuse cervical adenopathy in patients with ARPCs.
- Imaging usually could not differentiate between a solitary parotid LEC,
- a branchial cyst, and some cystic Warthin's tumors. Extraparotid lesions
- were either branchial cysts or cystic Warthin's tumors. Physicians
- should be aware of the variety of different inclusion-type cysts that
- may occur in the parotid gland and parapharyngeal space, all of which
- may have similar imaging appearances. Although imaging clearly
- identifies these cysts and may suggest a specific diagnosis, it must
- always be remembered that the precise diagnosis remains in the province
- of the pathologist.
