Arthroscopic Debridement of Intrapelvic Abscess With Coexistent Septic Hip in an Adult Female: A Technical Note

The aim of this study was to describe the technique for debridement of an intrapelvic abscess through an arthroscopic approach. We present a 24-year-old female with an obturator internus muscle abscess that extended across the obturator membrane and into the hip joint. Decompression of the intrapelvic abscess through hip arthroscopy was planned after close examination of preoperative images. Intrapelvic space was safely accessed by hip arthroscopy. The patient was asymptomatic and had normalized biomarkers at 6 months; however, the abscess recurred at 1 year postoperation. Details of the technique for intrapelvic access and anatomic structures at risk are described in this study.

Obturator Internus Muscle Abscess (OIMA) Successfully Treated With CT-Guided Trans-gluteal Drainage and Antibiotics. A Case Report and Literature Review

Background: Obturator Internus Muscle Abscess (OIMA) is a rare cause of infection around the adult hip with a handful of cases reported in the literature. The management usually consists of antibiotics and open surgical drainage. Case: We present a case of a 38-year old diabetic gentleman with an OIMA causing mass effect and shifting of intrapelvic organs. To our knowledge, this is the first case that was successfully treated with CT- guided trans-gluteal drainage and culture-specific antibiotics.

Internal obturator muscle abscess caused by Klebsiella pneumoniae

Obturator internus muscle abscess is an infrequent form of pyomyositis. To date, this disease has been described almost exclusively in children and young adults, and in most cases the causative agents are Gram-positive bacteria. We present the first report of obturator internus muscle abscess caused by a highly antibiotic resistant Klebsiella pneumoniae, in an elderly diabetic patient. Once considered very rare, Gram-negative pyomyositis is increasingly reported, and is an important concern in diabetic patients. Since pyomyositis can easily be missed if not considered, physicians should become familiar with this condition, and consider it in the differential diagnosis of septic diabetic patients.

Obturator Internus Muscle Abscess in Children

The authors describe four cases of obturator internus muscle (OIM) abscess in children, including their clinical presentations and treatment. This was a retrospective chart review. Children and adolescents younger than 18 years discharged between July 1, 1985, and September 30, 1998, from Brenner Children's Hospital with the diagnosis of muscle abscess or pelvic abscess were identified. A total of 56 patients were identified with the diagnosis of muscle abscess or pelvic abscess. OIM abscess was defined by radiologic findings of an inflammatory process with fluid collection in the OIM, along with the clinical findings suggestive of an OIM abscess. Four of the patients met the definition of OIM muscle abscess. The common presenting features were fever, limp, and hip pain. Computed tomography or magnetic resonance imaging was diagnostic in all four patients, and Staphylococcus aureus was the causative agent in each. All the patients recovered, one after surgical drainage and the other three after antimicrobial therapy alone or with needle aspiration. The presentation of OIM pyomyositis is similar to that of psoas muscle pyomyositis and other infectious processes of the pelvis and hip. The S. aureus is the most common etiologic agent but not the only one reported. Most patients can be managed without open surgical drainage, but needle aspirations may be helpful both therapeutically and diagnostically.
