Purpose: Pyomyositis is a rare disease in temperature climate region. The diagnosis of pyomyositis is often delayed, and pyomyositis is often misdiagnosed in the emergency department. Methods: The medical records of 11 patients who were diagnosed as having traumatic pyomyositis in the emergency department at Samsung Medical Center in Seoul, Korea, between 2000 and 2006 were reviewed. Their clinical features, such as history, symptoms, clinical findings, duration from onset of symptoms to diagnosis, medical history, laboratory data, results of imaging studies and clinical course were collected. Results: The psoas muscles were most commonly involved. Computer tomography and magnetic resonance imaging aided in accurate diagnosis of the infection and of the extent of involvement. Incision, drainage, and antibiotics therapy eradicated the infectioin in all patients Conclusion: Pyomyositis should be a part of the differential diagnosis for patients with traumatic muscle pain. Radiologic evaluation, such as computer tomography and magnetic resonance imaging, must be considered in the diagnosis of traumatic pyomyositis.

Bacterial infection of skeletal muscle can lead to the formation of abscesses. Primary pyomyositis is typically seen in tropical countries, and Staphylococcus aureus is the commonest causative organism. We present a case of acute adductor magnus muscle abscess (pyomyositis) with spread to adjacent thigh compartments via the perforators without iliopsoas muscle involvement. Due to the involvement of the entire thigh compartment, systemic antibiotic treatment alone was insufficient, whereas surgical drainage improved the clinical picture. The aetiological organism was S. aureus. Herein, we report the case of a patient who had primary pyomyositis, rather than a secondary type, that spread to the posterior and lateral aspect of the thigh through the second and third perforators, which pierce the adductor magnus muscle belly before entering the femur.

저자들은 평소 건강하던 비 월경 시기의 13세 여아에서, 특별한 선행 요인 없이 발생한 화농성 근염과 이에 동반된 TSS 1례를 경험하였기에 문헌 고찰과 함께 보고하는 바이다.

화농근육염은 골격근의 원발성 세균 감염으로, 주로 대퇴사두근이나 둔근에 발생한다. 화농근육염의 병리기전은 잘 알려져 있지 않으나 국소부위의 외상과 동반된 균혈증에 의한 것으로 설명되며, Staphylococcus aureus가 가장 흔한 원인균이다. Mycobacterium tuberculosis은 폐결핵을 일으키는 경우가 가장 흔하며, 활동성 폐결핵과 근골격계 결핵이 동반되는 경우는 약 30%이다. 근육내 결핵은 폐결핵을 일으키는 Mycobacterium tuberculosis가 근육 내로 침입하여 발병하는 것으로, 폐외 결핵 중 비교적 드문 형태이다. 저자들은 17개월 여아에서 다른 부위의 결핵을 동반하지 않은 근육내 결핵 1례를 경험하였기에 문헌 고찰과 함께 보고하는 바이다.

The diagnosis of pyomyositis in the pelvic region is difficult, as its incidence is relatively, with symptoms that mimic those of discogenic pain. Sciatica is a common presentation of a prolapsed lumbar disc. Less common causes, such as spinal stenosis, pelvic tumors or even primary nerve tumors can also cause these symptoms. Magnetic resonance imaging (MRI) is a useful diagnostic tool. Herein, the case of a patient with an acute pyogenic infection in the iliopsoas muscle, presenting with sciatica, is reported. This is a rare infective disease, which if promptly treated with intravenous antibiotics, can be completely resolved; otherwise, it can result in deep abscess formation, sepsis and death.

Not all sciatica-like manifestations are of lumbar spine origin. Some of them are caused at points along the extra-spinal course of the sciatic nerve, making diagnosis difficult for the treating physician and delaying adequate treatment. While evaluating a patient with sciatica, straightforward diagnostic conclusions are impossible without first excluding sciatica mimics. Examples of benign extra-spinal sciatica are: piriformis syndrome, walletosis, quadratus lumborum myofascial pain syndrome, cluneal nerve disorder, and osteitis condensans ilii. In some cases, extra-spinal sciatica may have a catastrophic course when the sciatic nerve is involved in cyclical sciatica, or the piriformis muscle in piriformis pyomyositis. In addition to cases of sciatica with clear spinal or extra-spinal origin, some cases can be a product of both origins; the same could be true for pseudo-sciatica or sciatica mimics, we simply don't know how prevalent extra-spinal sciatica is among total sciatica cases. As treatment regimens differ for spinal, extra-spinal sciatica, and sciatica-mimics, their precise diagnosis will help physicians to make a targeted treatment plan. As published works regarding extra-spinal sciatica and sciatica mimics include only a few case reports and case series, and systematic reviews addressing them are hardly feasible at this stage, a scoping review in the field can be an eye-opener for the scientific community to do larger-scale prospective research.
