Most likely diagnosis? Sialadenitis Ranula Tumor Sialolithiasis Sialolithiasis most commonly affects submandibular gland (80-90%) due to tortuous duct and calcium-rich secretions. 3 / 15 The most appropriate initial imaging for suspected salivary stone is MRI Sialogram Ultrasound CT scan Ultrasound is first-line - no radiation, can visualize stones, assess duct dilation, and guide procedures. 4 / 15 Patient presents with rapidly growing parotid mass and facial weakness. Most concerning for? Pleomorphic adenoma Warthin tumor Mucoepidermoid carcinoma Adenoid cystic carcinoma Facial nerve involvement, rapid growth, pain, and fixation strongly suggest malignancy. Requires immediate biopsy. 5 / 15 The most common malignant tumor of minor salivary glands is Adenoid cystic Acinic cell Mucoepidermoid Squamous cell Adenoid cystic carcinoma is most common in minor glands, especially palate. Known for perineural invasion. 6 / 15 A 45-year-old presents with a painless, slowly growing mass in the parotid. What is the most common benign tumor? Warthin tumor Basal cell adenoma Oncocytoma Pleomorphic adenoma Pleomorphic adenoma is the most common benign tumor (80% of benign parotid tumors). Typically presents as painless, slow-growing mobile mass. 7 / 15 A patient with HIV presents with bilateral parotid enlargement. The most likely underlying pathology is Bacterial infection Viral sialadenitis Lymphoepithelial cysts Lymphoma HIV-associated lymphoepithelial cysts are common in HIV. Presents as bilateral, painless parotid enlargement. 8 / 15 Which of the following conditions may require immediate surgical treatment? Ranula Sialolithiasis Viral sialadenitis Deep lobe abscess Deep lobe parotid abscess can spread to parapharyngeal space causing airway compromise. Treatment includes broad spectrum antibiotics and drainage. 9 / 15 A woman with dry eyes, dry mouth, joint pain. Most likely diagnosis? Lymphoma IgG4 disease Arthritis Sjögren's syndrome Sjögren's syndrome - autoimmune condition affecting salivary and lacrimal glands. Associated with positive SSA/Ro antibodies. 10 / 15 Patient develops xerostomia after starting new medication. Most likely class? Antihypertensives Antidepressants Antibiotics Anticholinergics Anticholinergics are most common cause of drug-induced xerostomia through muscarinic blockade. 11 / 15 The most concerning feature of malignant transformation in pleomorphic adenoma is Facial weakness Pain Firmness Rapid growth Rapid growth in longstanding pleomorphic adenoma suggests malignant transformation (carcinoma ex pleomorphic adenoma). 12 / 15 During parotidectomy, which structure most reliably identifies the facial nerve trunk? Styloid process Tragal pointer Retromandibular vein Digastric muscle The tragal pointer is a reliable landmark - facial nerve is 1-2cm deep and anterior to it, lying just inferior to the tympanomastoid suture. 13 / 15 Child presents with bilateral painful parotid swelling. Most likely cause? Bacterial infection Stones Viral sialadenitis Juvenile recurrent parotitis Viral sialadenitis (commonly mumps) is most common cause of bilateral parotid swelling in children. 14 / 15 The most reliable test for Sjögren's syndrome diagnosis is Salivary flow Anti-SSA antibodies Schirmer test Minor gland biopsy Minor salivary gland biopsy showing focal lymphocytic sialadenitis has highest specificity for diagnosis. 15 / 15 Patient post-radiation with severe dry mouth. Best initial treatment? Pilocarpine Antibiotics Artificial saliva Surgery Pilocarpine stimulates residual salivary function. Start with salivary substitutes and maintain oral hygiene.
