ABSTRACT
Schwannoma is the most common benign tumor of peripheral nerves and usually appears on the trunk, head and neck, or extremities. A mass arising at popliteal fossa can be misdiagnosed as a popliteal cyst. We report on a rare case of a popliteal schwannoma mimicking a popliteal cyst in a 39-year-old female who showed a clinical presentation similar to that of a popliteal cyst. Diagnosis was delayed until ultrasonographic evaluation was performed due to its anatomical location, the same as that of a popliteal cyst. We describe the clinical significance and ultrasonographic findings of the schwannoma for initial differential diagnosis from a popliteal cyst.

Iliacus muscle is the strongest hip flexor of gluteal region that acts with psoas muscle, whereas gluteus maximus muscle is the largest muscle engaged in extension and external rotation of the hip. Mountaineering requires strong contractile force of both flexor and extensor around the hip. A 57-year-old man presented to our hospital with severe pain in left groin after mountaineering for 5 hours without a break. Magnetic resonance imaging revealed incomplete rupture of iliacus muscle and strain of gluteus maximus muscle. Conservative treatment was done. At 3 months of follow-up, he returned to normal life. If we are going to climb mountain, it is important to start warming up with some stretches, take a break while climbing, and use climbing sticks. There have been no report about athletic injury of both iliacus and gluteus maximus after mountaineering. So we report this case with a review of the literature.
