Background: This is a rare case of piriformis
syndrome. We discuss the patient’s symptoms, imaging study results, laboratory
examination findings, and prescribed treatment in an attempt to determine the
possible mechanisms or reasons for this patient’s development of piriformis
syndrome. Methods: The patient is a 22-year-old
female soldier who was admitted for lower back pain with soreness
radiating to her right buttock and right lower extremity. We found that she had leg length discrepancy under X-ray finding. She
was diagnosed piriformis syndrome by physical examination and Magenetic
Resonance Image. Results: We performed
scanography for lower extremities revealed a left femur length of 42.7 cm, a right femur length of 43.3 cm, a left tibia length of 33.2 cm, and a right tibia length of 33.6 cm; her left lower extremity was 1 cm shorter than her right. The MRI of
sacrum also reveals hypertrophy of right
piriformis muscle. Conclusions: Piriformis
syndrome might be caused by short-term compensation in congenital leg length discrepancy.
The patient with leg length discrepancy changed posture when standing, walking,
and running. These compensation postures could lead to abnormality position of bones
where there is insertion of the muscle.
retroperitoneal tumors are rare, and benign retroperitoneal tumors are
exceptionally rare. Herein, we present a very rare case of benign concomitant
retroperitoneal intramuscular hemangioma and intravascular papillary
endothelial hyperplasia, with the unusual presentation of lumbosacral plexopathy.
After surgical treatment and rehabilitation, the patient recovered uneventfully.
This case report should serve to remind physicians of the rare condition of a
retroperitoneal tumor leading to a neurological deficit.
