A 38-year-old woman presents with progressive bilateral hearing loss over 6 weeks, along with tinnitus and aural fullness. Audiometry reveals the pattern marked **A** in the diagram—bilateral rapidly progressive sensorineural hearing loss across all frequencies, with >30 dB loss at multiple frequencies. She denies sudden onset and has no history of noise exposure. Systemic examination reveals a malar rash and positive ANA. Which of the following is the most likely diagnosis?
A. Sudden sensorineural hearing loss with incomplete recovery
B. Noise-induced hearing loss with bilateral symmetrical involvement
C. Autoimmune inner ear disease (AIED) secondary to systemic lupus erythematosus
D. Age-related presbycusis with accelerated progression
Explanation
Why Autoimmune inner ear disease (AIED) secondary to systemic lupus erythematosus is right
The clinical presentation—bilateral rapidly progressive SNHL developing over weeks (6 weeks in this case), >30 dB loss at multiple frequencies across all frequency ranges, accompanied by tinnitus, aural fullness, and systemic features (malar rash, positive ANA)—is pathognomonic for AIED as defined by McCabe (1979). The timeframe of weeks-to-months is the critical distinguishing feature of AIED. The presence of systemic autoimmune features (SLE in this case) indicates secondary AIED. According to Cummings Otolaryngology, AIED is characterized by rapidly progressive bilateral asymmetric SNHL developing over weeks to 3 months, and can be secondary to systemic autoimmune diseases including SLE. The pattern marked A (bilateral rapidly progressive SNHL across all frequencies) is the hallmark audiometric finding of AIED.
Why each distractor is wrong
Sudden sensorineural hearing loss with incomplete recovery: Sudden SNHL develops acutely (over hours to days), not over weeks. The temporal profile in this case (6 weeks) is incompatible with sudden SNHL, which is the defining distinction between sudden SNHL and AIED.
Age-related presbycusis with accelerated progression: Presbycusis is a slowly progressive, high-frequency sloping loss (pattern D) developing over years, not weeks. The bilateral rapid progression over 6 weeks with systemic features rules out presbycusis.
Noise-induced hearing loss with bilateral symmetrical involvement: Noise-induced loss typically produces a noise-notch at 4 kHz (pattern C), not uniform loss across all frequencies. Additionally, there is no history of noise exposure, and the presence of systemic autoimmune features makes this diagnosis untenable.
High-YieldNEET PG
AIED is defined by rapidly progressive bilateral SNHL over weeks-to-3-months; steroid responsiveness is both diagnostic and therapeutic; always search for secondary causes (SLE, GPA, Cogan syndrome, sarcoidosis).
