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.展开更多

Hence, the prognostic factors of long-term outcome beyond 6 months after CH are clinically valuable, however only three studies were reported in the literature. Sixty-one patients with CH were retrospectively analyzed at least 6 months after hemorrhage. The long-term outcome of all patients and long-term functional status of survivors beyond 6 months (the patients who died within 6 months after hemorrhage were excluded) were assessed using the modified Rankin Scale (mRS): favorable outcome (mRS 0 - 2) and unfavorable outcome (mRS 3 - 6). All of the prognostic factors were analyzed by univariate and multivariate Cox proportional hazards regression models. There were 16 (26.2%) patients in the favorable outcome group and 45 (73.8%) in the unfavorable outcome group with respect of long-term outcome in all patients. The radiological brainstem compression (HR = 3;p = 0.015) was shown to be an independent predictor. On the other hand, 46 out of 61 (75.4%) patients survived beyond 6 months. In total, 16 (34.7%) patients had a favorable functional status, and 65.3% (30/46) had a persistent unfavorable functional status. Moreover, only age 365 years (HR = 3;p = 0.019) was an independent predictor. Radiological brainstem compression and age 365 were respectively shown to be a strong prognostic factor for long-term outcome and functional status among survivors beyond 6 months after hemorrhage in patients with CH.展开更多

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.展开更多
