[Right pyriform sinus fistula with infection of left neck: a case report]
Abstract:
In this article, a case of right pyriform fossa fistula, with left cervical infection as the main manifestation is reported. Ultrasound showed that there was an inhomogeneous echo mass in the dorsal side of the left lobe of thyroid. MRI showed that there were infectious signal behind the bilateral thyroid gland, but mainly on the left side. Fistula was found in the right pyriform fossa under suspension laryngoscope, and CO₂ laser cauterization was performed to cauterize this fistula.
Insights
A rare right pyriform fossa fistula presented as a left cervical infection. Imaging revealed thyroid abnormalities, and diagnosis was confirmed via laryngoscopy, leading to successful CO₂ laser fistula cauterization.
Area of Science:
- Otolaryngology
- Head and Neck Surgery
- Medical Imaging
Background:
- Pyriform fossa fistulas are rare congenital anomalies, often presenting with recurrent cervical infections.
- Left-sided cervical infection can be an atypical manifestation of a right-sided pyriform fossa fistula.
- Diagnostic imaging modalities like ultrasound and MRI play a crucial role in identifying the extent and origin of infection.
Observation:
- A case presented with left cervical infection as the primary symptom.
- Ultrasound identified an inhomogeneous echo mass in the left thyroid lobe.
- MRI revealed infectious signals posterior to both thyroid lobes, predominantly on the left.
Findings:
- A right pyriform fossa fistula was identified using suspension laryngoscopy.
- The fistula was successfully treated with CO₂ laser cauterization.
Implications:
- This case highlights the importance of considering pyriform fossa fistulas in atypical cervical infections.
- Accurate diagnosis through advanced imaging and laryngoscopy is essential for effective treatment.
- CO₂ laser cauterization offers a minimally invasive option for managing pyriform fossa fistulas.
