Obturator internus pyomyositis is a rare disease that is more commonly found in tropical countries. Due to its infrequent occurrence, it is a differential of hip pain that has not been sufficiently considered, which often results in delayed diagnosis. We present a case report of a 4 year old boy with pyomyositis of obturator internus as well as externus. He was treated successfully with intravenous antibiotics. A comparison is made with other case reviews to identify symptoms and signs that could help in diagnosing the condition early and accurately so as to initiate intravenous antibiotics, the mainstay treatment in a timely fashion, eventually avoiding surgical drainage of the sequelae when it becomes an abscess.

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.

Pyomyositis is a bacterial infection of the skeletal muscle with Staphylococcus aureus being the most common pathogen. Pyomyositis by salmonella is quite rare accounting for less than 1% of the total pyomyositis, and has some different characteristics and a poor prognosis compared with those of the typical pyomyositis caused by other bacteria. Among these differences, an older age, other combined diseases, and an immune deficient condition are factors predisposing a patient to pyomyositis by salmonella. We experienced a very rare case of pyomyositis by salmonella at the inguinal area in a multiple myeloma patient. This is the first case reported in South Korea.

Pyomysitis is a primary acute bacterial infection of large skeletal muscule, usually occuring in the absence of specific cause of infection. Pyomyositis has been reported mainly in tropical countries and was rare in temperate climates. but it has been recognized with increasing frequency. Toxic shock syndrome(TSS) is an acute mutisystemic disease characterized by high fever, hypotension, multisystem dysfunction and erythematous rash followed by skin desquamation 8-12 days after onset. Especially, TSS and pyomyositis are rare conditions in the pediatric population. We experienced one case in a healthy 13-year-girl who developed pyomyositis of the right ileac and gluteal muscles associated with TSS caused by methicillin resistant Staphylococcus aureus. We reports a case of acute pyomyositis with TSS, in which the diagnosis was difficult because of the relative rare incidence in temperate climates and its vague symptoms. To our knowledge, this is the first reported case of pyomyositis with TSS in Korean pediatric population.

A case of pyomyositis of right pyriformis and iliacus muscle in a healthy 13 year old male patient is presented and discussed. Pyomyositis is a primary acute bacterial infection of large skeletal muscles, associated with abscess formation. Since pyomyositis has been reported mainly in tropical countries and is rare in temperate climates, the name 'tropical myositis' is often used. Outside the tropics, pyomyositis is often associated with immune compromised state, and vigorous muscle acivity may have a role in some cases of pyomyositis. In this case, thirteen year old healthy boy developed severe right buttock pain after vigorous gymnasium activity and was treated with acutpucture, then showed high fever and aggrevation of pain. This case was thought to be associated muscle injury due to vigorous gymnasium activity and transient bacteremia following cutaneous acupuncture. He was treated with ultrasono guided needle aspiration and parenteral antibiotics successfully.

Pyomyositis is an acute, suppurative bacterial infection of striated muscle. It occurs primarily, and not from contiguous infection. It is considered rare in temperate climates. There has been no report of pyomyositis in the Korean dermatologic literature to date. We report a case of pyomyositis which developed in a 53-year-old male. The patient was admitted for the treatment of cutaneous leukocytoclastic vasculitis on his entire body. He was treated with oral corticosteroids for approximately three weeks. The skin condition did show improvement; however, the patient developed a persistent fever and a newly-found mass on the right upper back. The mass was diagnosed as an abscess, replacing the striated muscles of the back by sono-guided needle aspiration. After surgical intervention and IV antibiotic treatment, the symptoms and mass on the back disappeared. We speculate that the underlying skin condition and long-term use of oral corticosteroids predisposed the patient to pyomyositis.

Pyomyositis is a primary bacterial infection of skeletal muscle and this is on the increase worldwide among children as well as young adults. We report herein on a case of a 29-year-old male with pyomyositis of the obturator internus. The fact that pyomyositis predominantly affects the muscles of the lower limb and it is confined to the obturator internus muscle has been poorly recognized. CT with an enhancement was an accurate imaging modality to image the obturator internus muscle and to ascertain the diagnosis for this case. The patient was managed with antibiotics and surgical intervention was not necessary. Pyomyositis of the obturator internus muscle needs to be differentiated from septic arthritis of the hip. The present study reports the clinical signs and treatments of pyomyostis and we review the relevant literature.

Sacroiliac joint block can be performed for the diagnosis and treatment of sacroiliac joint dysfunction. Although sacroiliac joint block is a common procedure, complications have not been reported in detail. We report a case of iliacus pyomyositis and sacroiliac joint infection following a sacroiliac joint block. A 70-year-old female patient received sacroiliac joint blocks to relieve pelvic pain. The patient was admitted to the emergency room two days after the final sacroiliac joint block (SIJB) with the chief complaints of left pelvic pain corresponding to a visual analogue scale (VAS) score of 9 and fever. A pelvic MRI indicated a diagnosis of myositis. After 1 month of continuous antibiotic therapy, the patient's erythrocyte sedimentation rate (ESR) and C-reactive protein (CRP) level remained elevated. A 67Ga SPECT/CT was done. Abnormal uptake was seen at the left sacroiliac joint (SIJ), and septic sacroiliitis was suspected. The CRP normalized to 0.29 mg/dl and the ESR decreased to 60 mm/hr, and the patient had no fever after 57 days of antibiotic therapy. She was directed for follow up at an outpatient clinic.

Vibrio cholerae non-O1 mainly causes gastroenteritis and rarely causes extraintestinal infections, such as bacteremia. Skin and soft tissue infections are also possible, but the incidence rate is very low. Although the most common cause of pyomyositis is Staphylococcus aureus, Gram-negative organisms such as Vibrio species may also cause pyomyositis in patients with chronic liver disease. Pyomyositis caused by Vibrio cholerae non-O1 has not been reported in Korea. Here, we report a case of pyomyositis caused by V. cholerae non-O1 bacteremia in a patient with liver cirrhosis following seafood exposure. This case study suggests that V. cholerae, as well as V. vulnificus, should be considered when soft tissue infections occur in patients with liver cirrhosis after seafood exposure. In addition, physicians should consider imaging studies for a prompt diagnosis if the patient complains of severe pain disproportionate to the skin manifestation.
