A 40-year-old woman was referred to our hospital with right lower back pain as the chief complaint. Contrast-enhanced computed tomography (CT) showed a partially-solid tumor within a cyst measuring approximately 6 cm in diameter in the right renal hilum. The solid part was enhanced in the early phase and contrast medium was washed out earlier in the solid part than in the parenchyma in the equilibrium phase. Plain CT revealed partial cyst wall calcification. A soft tissue shadow approximately 10 mm in diameter in the dorsal inferior vena cava at the upper pole of the kidney and a solid tumor adjacent to the iliopsoas muscle and the kidney were detected...

Primary abscess of the iliopsoas muscle in children is uncommon, especially due to Streptococcus pyogenes (group A streptococcus: GAS), which causes a variety of diseases ranging from pharyngitis to invasive life-threatening infection. We present primary iliopsoas abscess in a nine-year-old boy presenting with fever, mild disturbance of consciousness, limp, and pain in the right loin. Magnetic resonance imaging and isolation of GAS from both blood and abscess samples led us to the confirmative diagnosis. The patient recovered after treatment comprising drainage and intravenous antibiotics...

Snapping hip syndrome is an audible or palpable snap in a hip joint during movement which may be accompanied by pain or locking. It is typically seen in young athletes performing activities requiring repeated extreme movements of the hip. It may also follow a physical trauma, intramuscular injections or surgeries. There are two main forms of snapping hip: extra- or intra-articular. Extra-articular snapping hip is elicited by an abnormal movement of specific tendons and is divided into two forms: internal and external...

A 55-year-old woman presented with a mucopurulent sinusal discharge from the right supragluteal region, with symptoms over the previous five months. This abscess began as a slowly swelling growth, which eventually turned into a discharging sinus, and she was diagnosed with a gluteal abscess. The patient underwent incisional drainage, and intra-operatively, the sinus tract could be seen extending to the retroperitoneum. A subsequent CT scan and an MRI of the abdomen revealed a large heterogeneous retroperitoneal cystic mass on the right side of midline, extending inferiorly into the anterior thigh along the iliopsoas...

BACKGROUND: Several infectious processes of intra-abdominal origin may atypically present as skin or soft tissue infections or abscess in the thigh. CASE REPORT: We describe the case of a 73-year-old woman who presented to the emergency department with the clinical picture of a skin infection of the right leg. The patient's condition deteriorated during medical treatment with intravenous antibiotics. Subsequent radiologic imaging revealed that the complaints were caused by a bulging retroperitoneal appendicular abscess along the iliopsoas muscle, although the patient experienced no abdominal symptoms...

AIM OF THE STUDY: To investigate the magnetic resonance imaging (MRI) features of skeletal muscle metastases (SMM). MATERIAL AND METHODS: The records of 31 patients with proven SMM were retrospectively reviewed. Clinical history, type of primary malignancy, location of metastases, and MRI features of SMM were evaluated. Based on MRI findings, SMM were divided into three MRI types. The correlation between MRI types with ages and pathology category, between MRI types of SMM and ages, as well as MRI types of SMM and pathology category were analysed with Spearman's rho...

We describe a 29-year-old patient who complained of left thigh muscle weakness since he was 23 and of moderate proximal weakness of both lower limbs with difficulty in climbing stairs and running since he was 27. Mild weakness of iliopsoas and quadriceps muscles and muscle atrophy of both the distal forearm and thigh were observed upon clinical examination. He harboured a novel c.1150-3C>G substitution in the DMD gene, affecting the intron 10 acceptor splice site and causing exon 11 skipping and an out-of-frame transcript...

INTRODUCTION: Hemophilic pseudotumor is a rare but well documented complication seen in approximately 1-2% of patients with hemophilia. The incidence continues to decrease, likely because of increasingly sophisticated techniques in managing factor deficiency. We present a case of hemophilic pseudotumor in a patient without hemophilia, an exceptionally rare entity, and outline a hybrid approach to treatment. PRESENTATION OF CASE: The patient presented with a left sided iliopsoas mass and associated radiculopathy, with a history of a poorly characterized bleeding diathesis and Noonan's syndrome...

BACKGROUND: Iliopsoas tendon impingement is one possible reason for persistent groin pain and diminished functional outcome after THA. So far, estimation by eye and palpation is the standard procedure to intraoperatively assess the distance of the cup to the anterior rim. However, novel technologies such as imageless navigation enable intraoperative measurements of the cup in relation to the psoas tendon and bony landmarks. QUESTIONS/PURPOSES: We asked whether psoas impingement (1) can be reduced using imageless navigation compared with the standard technique and (2) is associated with specific patient characteristics...

Ischiofemoral impingement (IFI) is an often unrecognized cause of hip pain caused by abnormal contact between the lesser trochanter and the ischium. To date, surgical treatment for those whose pain is not relieved by activity modification and steroid injections has not been defined. This study describes our imaging protocol and reports the results of arthroscopic, lesser trochanteric resections that were performed to treat this condition. Seven patients with symptomatic, MRI-documented IFI had ultrasound injections of ropivicaine and steroid into their ischiofemoral space...

This article outlines adductor-related groin pain, pubic-related groin pain, inguinal-related groin pain, and iliopsoas-related groin pain, with a description of the corresponding functional anatomy and imaging findings. The imaging has been described mainly in terms of MR imaging findings as this is the principal imaging modality used to investigate groin pain, although plain radiographs and ultrasound can be very useful adjuncts in specific circumstances, especially if an alternative pathology needs to be excluded...

General medical conditions are an important part of the differential diagnosis in athletes presenting with pain or injury. A psoas abscess is a collection of pus in the iliopsoas muscle compartment and is a rare cause of hip, low back, or groin pain. Psoas abscesses may have significant morbidity and mortality, as 20% progress to septic shock. Presenting symptoms are generally nonspecific and the onset may be subacute. Clinical presentation may have features suggestive of other diagnoses, including septic hip arthritis, iliopsoas bursitis, and retrocecal appendicitis...
