MR appearance of anomalous insertion of the medial meniscus. A case report

Area of Science:

• Orthopedic Surgery
• Radiology
• Medical Imaging

Background:

• Anomalous medial meniscus is a rare condition, often presenting diagnostic challenges in clinical settings.
• Accurate diagnosis is crucial for appropriate patient management and treatment planning.

Observation:

• A 41-year-old male patient presented with knee symptoms.
• Magnetic resonance (MR) imaging revealed an anomalous medial meniscus with a tear.

Findings:

• The MR imaging findings were instrumental in achieving a pre-arthroscopic diagnosis.
• Arthroscopy confirmed the presence of the anomalous medial meniscus tear.
• The identified tear was not the cause of the patient's presenting symptoms.

Implications:

• This case highlights the utility of MR imaging in diagnosing rare meniscal anomalies.
• Early and accurate diagnosis can guide surgical planning and patient expectations.
• Understanding the relationship between meniscal anomalies and symptoms is key in clinical practice.
