“…Initial radiological investigations may include plain radiographs, which are normally unremarkable, unless underlying discitis or vertebral osteomyelitis have been present for the previous few weeks. Ultrasonography only diagnosis 60% of psoas abscess cases, while CT reaches 80–100% and is considered the ‘gold standard’ 5 11. The most common CT feature is usually a focal hypodense lesion within a larger muscle, with low attenuation, but this sign can also be seen in neoplasms and haematomas 12–14.…”

The authors report the case of a 69-year-old man with chronic obstructive pulmonary disease and previous pulmonary tuberculosis, who presented to the emergency department with abdominal and low back pain, anorexia and weight loss, rapidly evolving into shock. An initial CT scan revealed pulmonary condensation with associated cavitation and an iliopsoas mass suggestive of a psoas abscess. He was admitted in an intensive care unit unit; after a careful examination and laboratory assessment, the aetiology was yet undisclosed. MRI showed multiple retroperitoneal lymphadenopathies, bulky nodular adrenal lesions and bilateral iliac lytic lesions. Hypocortisolism was detected and treated with steroids. A CT-guided biopsy to the psoas mass and lytic lesions identified infiltration of non-small lung carcinoma. The patient died within days. Psoas metastases and adrenal insufficiency as initial manifestations of malignancy are rare and can be misdiagnosed, particularly in the absence of a known primary tumour.

“…Although ultrasonography is enough for the diagnosis, computarized tomography is much more sensitive in the diagnosis of abscess (7). In children with low adipose mass, contrast uptake is decreased in soft tissues and this affects accuracy (10,11). Magnetic resonance imaging is the best method, since it defines both anotomical structures and pathological abnormalities well (11,12).…”

Tuberculosis as an important health problem of our age causing death of 2 million people each year. The incidence of tuberculosis in the pediatric age group is 1.3 millions/year and it is estimated that 450,000 cases result in death. WHO reports that %15-25 of cases are extrapulmonary tuberculosis patients. Here we present a rare case of abdominal tuberculosis who had no immunsupression with isolated bilateral psoas abscesses and inguinal lymph node involvement. (Turk Arch Ped 2011; 46: 331-3)

Psoas abscess was first described by Mynter in 1881. Though rare, its prevalence is increasing with advances in radiology and an increasing ability to accurately diagnose the condition. The symptoms of a psoas abscess can be insidious and nonspecific, and patients often present with a limp, fever, weight loss, and flank or abdominal pain.A psoas abscess can be classified as either primary or secondary depending on the presence or absence of an underlying disease. Primary psoas abscess has become more prevalent in the developed world, especially in immuno-compromised patients.We present the case of a 48 year old man who presented with fever, left hip pain and difficulty weight-bearing. He had a past medical history of chronic renal failure secondary to hypertension. Following laboratory, radiological and microbiological analyses the patient was diagnosed as having a Staphylococcus Aureus hip sepsis secondary to a psoas abscess.Psoas abscess should be included as a differential diagnosis in all patients presenting with hip pain and constitutional symptoms. The case is discussed with reference to the literature.
