Question
31 out of 39
 

A 55 years old female presents with tinnitus, dizziness and h/o progressive deafness. Differential diagnosis includes all except: (LQ)



A Acoustic neuroma
B Endolymphatic hydrops

C Meningioma
D Histiocytosis-X

Ans. D Histiocytosis X Ref. Dhingra 5th/ed p 38; Harrison 7 7th/ed p 2603

Acoustic neuroma and endolymphatic hydrops (Meniere's disease) can lead to SNHL and tinnitus (Dhingra 5/e p. 38). Meningioma can cause deafness, and tinnitus as a part of Neurofibromatosis type 2 syndrome (Harrison 7 7th/ed p 2603) and its peak incidence occurs in middle age.

No where it is mentioned histiocytosis X causes deafness and tinnitus. Another point which goes against it is the age of patient (55 years) as histiocytosis occurs mainly in children.
