Congenital Peri-Lymphatic Fistula: is CT Imaging Enough?

Area of Science:

• Pediatric Radiology
• Otolaryngology
• Medical Imaging

Background:

• Congenital sensorineural hearing loss (SNHL) infrequently co-occurs with identifiable radiological anomalies.
• Inner ear malformations are observed in a minority of SNHL cases.
• Congenital perilymphatic fistula is an exceptionally rare finding in this patient population.

Purpose of the Study:

• To report a rare case of a two-year-old child diagnosed with both congenital perilymphatic fistula and inner ear malformations.
• To emphasize the utility of comprehensive imaging in diagnosing rare congenital auditory anomalies.

Main Methods:

• Diagnostic imaging including Computed Tomography (CT) and Magnetic Resonance Imaging (MRI) was performed.
• Radiological findings were correlated with the clinical presentation of congenital sensorineural hearing loss.

Main Results:

• The comprehensive imaging successfully identified concurrent inner ear malformations and a congenital perilymphatic fistula.
• These findings represent a rare combination of anomalies in a pediatric patient with SNHL.

Conclusions:

• This case underscores the importance of advanced imaging techniques in diagnosing uncommon congenital inner ear anomalies.
• The simultaneous presence of inner ear malformations and perilymphatic fistula, though rare, should be considered in the diagnostic workup of pediatric SNHL.
