A large, symptomatic synovial cyst of the lateral meniscus caused knee locking and effusion. Surgical excision resulted in complete symptom resolution and no recurrence, highlighting a rare presentation of this knee pathology.

Area of Science:

  • Orthopedic Surgery
  • Musculoskeletal Radiology
  • Pathology

Background:

  • Intra-articular synovial cysts are typically asymptomatic and incidentally discovered.
  • This case presents a rare, large synovial cyst originating from the lateral meniscus.

Observation:

  • A 50-year-old woman experienced progressive right knee pain, a palpable mass, locking, and effusion over five years.
  • Magnetic resonance imaging (MRI) revealed a large, multilobulated, nonhomogenous lesion within the intracondylar notch, mimicking a tumor.

Findings:

  • Diagnostic arthroscopy and subsequent limited lateral arthrotomy confirmed and excised a 2.5 x 2.5 cm synovial cyst.
  • Pathological examination verified the lesion as a synovial cyst, unusual for its size and symptomatic presentation.

Implications:

  • This case underscores that synovial cysts, though uncommon, can present as large, symptomatic, tumor-like masses requiring surgical intervention.
  • Complete excision led to excellent patient outcomes, with no recurrence at one-year follow-up.
