Lateral radicular cyst

Last edited: 4/15/2026

Overview

Lateral radicular cysts (LRCs) are benign lesions that typically arise from the lateral aspects of the neck, often associated with previous trauma or inflammation affecting the tonsillar region. These cysts can expand into the neck soft tissues without necessarily involving the tonsil directly.

Diagnosis

  • Histological confirmation is essential for diagnosis 1.
  • Imaging studies (e.g., ultrasound, CT, MRI) may help delineate the extent of the cyst 1.
  • Clinical presentation often includes a palpable mass in the lateral neck region 1.
  • Management

  • Primary Treatment: Complete surgical resection of the cyst is recommended 1.
  • Adjunctive Procedures: Ipsilateral tonsillectomy is not routinely necessary based on the study findings 1.
  • Follow-Up: Regular follow-up to monitor for recurrence is advised, with median follow-up periods extending up to 18 years showing no recurrence in the study cohort 1.
  • Special Populations

  • Pediatrics: No specific data provided in the abstracts 1.
  • Elderly: No unique considerations mentioned beyond general surgical risks 1.
  • Comorbidities: No specific guidance provided regarding management in patients with comorbidities 1.
  • Key Recommendations

  • Complete surgical resection of lateral radicular cysts is sufficient to prevent recurrence and complications without the need for ipsilateral tonsillectomy 1 (Evidence: Strong).
  • Regular long-term follow-up is essential to monitor for any signs of recurrence post-surgery 1 (Evidence: Moderate).
  • Histological confirmation should be obtained to definitively diagnose lateral radicular cysts 1 (Evidence: Strong).
