Case 9	32 year old male with left middle ear mass	Si787	Middle ear adenoma (middle ear carcinoid tumor)
Case 10	36 year old male with enlarging • painful mass over the left external auditory canal	Si787	Osteoma (0.7 cm)

Case 13	36 year old female with several year h/o left sided pulsatile tinnitis	Si787	Jugalotympanic paraglioma (glomus tympanicum)
Case 14	36 year old male with an enlarging • very painful mass over the left auditory canal	Si787	Osteoma (0.7 cm)
Case 15	60 year old woman with right middle ear lesion	Si787	Paraganglioma of the middle ear
Case 16	48 year old female with increased pressure in R ear for 6 months	Si787	Middle ear adenoma with neuroendocrine differentiation. Middle ear carcinoid. Well-differentiated neuroendocrine carcinoma
Case 17	47 year old male with left temporal bone lesion • destructive tumor of mastoid	Si787	Langerhans cell histiocytosis
Case 18	71 year old male with left ear lesion	Si787	Spindle cell SCC
Case 19	52 year old female with NF1 and a right postauricular mass	Si787	Neurofibroma • diffuse type
Case 20	43 year old female with chronic otitis media	Si787	Meningoencephalocele
Case 21	62 years old with left parotid mass with extension into the external auditory canal	Si787	Mucoepidermoid carcinoma • oncocytic type. Low to focally intermediate grade
Case 22	59 year old female	Si787	Paraganglioma
Case 23	40 year old male	Si787	Tenosynovial giant cell tumor • diffuse type (formerly pigmented villonodular synovitis)
Case 24	40 year old male	Si787	Tenosynovial giant cell tumor • diffuse type (formerly pigmented villonodular synovitis)
Case 25	69-year-old male with a left middle ear/mastoid mass and progressive hearing loss over the past 8 years • more pronounced in the left ear. Otoscopic examination revealed mass in the middle ear with an opacified tympanic membrane. CT scan as well as MRI were suspicious for middle ear mass versus inflammatory tissue (e.g. GPA). Of note • past MRI from 2018 also reported inflammatory changes in the left otomastoid region. -Obtain past MRI scans and hearing tests from UMass and outside Hospital for comparison.
