@entity1462 masquerading as XXXX and parotid obstruction: a case report and review of the literature.

@entity1 @entity455 @entity14291 @entity3359 @entity4 @entity1211 @entity1462
INTRODUCTION: @entity3359 caused by @entity14291 or duct stricture is one of the more common causes of non-infectious unilateral facial selling. @entity1462 of the head and neck are less common but may present with intermittent @entity4 . Phleboliths can be found in venous malformations of nearly all adult @entity1 and are a key diagnostic imaging finding. The clinical and radiographic appearance of phleboliths may resemble @entity14291 , making the diagnosis more difficult. We present a case of intermittent unilateral @entity4 cause by a @entity1211 involving the buccal space where the phleboliths were initially misdiagnosed as @entity14291 . STUDY DESIGN: Illustrative case report and literature review. METHODS: A 48 year-old @entity1 presented to our office with 9 months of intermittent left @entity4 . On bimanual examination, multiple small firm nodules were palpated in the left cheek. A computed tomography (CT) scan demonstrated multiple oval-shaped radiopaque lesions in the buccal space, initially interpreted as sialoliths. Magnetic resonance imaging (MRI) was obtained, confirming the diagnosis of @entity1211 with phleboliths. Sialendoscopy revealed a normal appearing parotid duct system without stricture or @entity14291 . Ultrasound revealed a buccal space @entity455 surrounding the distal Stensen's duct. RESULTS: Currently, the @entity1 is being observed and is clinically stable. Illustrative CT scan and MRI images are presented. A literature review shows that @entity1462 mimicking @entity3359 are rare. CONCLUSIONS: While unilateral @entity4 is commonly due to parotid sialoliths or parotid duct stenosis, other less common causes including @entity1462 should be considered. Phleboliths and sialoliths may appear similar on ono-contrast CT scan. Ultrasound, MRI, and sialendoscopy may be helpful in determining the etiology.
