 TI    Nodal inclusion cysts of the parotid gland and parapharyngeal space: a
       discussion of lymphoepithelial, AIDS-related parotid, and branchial

 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.
