US of the Major Salivary Glands: Anatomy and Spatial Relationships, Pathologic Conditions, and Pitfalls

Recurrent Warthin Tumor Presenting With Synchronous, Bilateral Parotid and Multi-Centric Upper Neck Involvement.

“…On ultrasound, Warthin tumors appear as well demarcated, hypo-echoic, and hypervascularized oval lesions [8]. In a retrospective study of 34 Warthin tumors, 94% of these tumors had greater uptake than normal parotid gland tissue on Tc-99m scintigraphy after lemon juice stimulation [9].…”

“…Most patients present with a solitary, painless mass in the peri-parotid area. Radiologic evaluation, whether it be with ultrasound, CT scans, or MRI, reveal well-demarcated, heterogeneous lesions [8,10,11]. A definitive diagnosis is usually rendered when FNA reveals monolayered sheets of oncocytic cells, lymphocytes, and amorphous, cystic debris [13].…”

Comparison of fine needle aspiration biopsy and histopathology in the evaluation of parotid masses

“…Parotis tümörlerinde preoperatif değerlendirme, parotise komşu yapılardan köken alan lezyonların ayrılmasında ve lezyonlara yönelik farklı tedavi yaklaşımları olması nedeniyle oldukça değerlidir. Doğru değerlendirme ile medikal tedavi, klinik takip ya da cerrahi tedavi seçeneklerinden birine karar verilmesi yanı sıra, preoperatif değerlendirme bezin fasial sinir ile yakın komşuluğu nedeniyle cerrahi planlama ve gereksiz cerrahiyi engellemek açısından da önemlidir 4,5 . Preoperatif patolojinin bilinmesi cerrahi planlamada da kolaylık sağlamaktadır.…”

Bilateral parotid swelling: a radiological review

“…[2][3][4] On ultrasound, a well-defined hypoechoic mass is characteristic, often containing multiple small cystic a b areas, but occasionally an almost entirely cystic mass is seen. 5 MRI reveals presence of a well-defined, partially cystic mass (the cystic component of fluid signal intensity and the solid component of intermediate signal intensity). Multiple or bilateral parotid ( Figure 13) or periparotid masses strongly suggest the diagnosis.…”

“…[1][2][3] Salivary gland imaging is currently performed by several modalities including MRI, CT, ultrasonography, scintigraphy and sialography. [1][2][3][4][5] The algorithm for imaging the salivary glands depends on the clinical scenario with which the patient presents to the clinician. In this article, we display a panel of imaging features of histologically proven bilateral parotid swelling to emphasize diagnostic differentiation based on imaging.…”
