“…Percutaneous aspiration of intra-abdominal masses has been advocated as a safe, effective diagnostic procedure in the paediatric age group. 8 The cytology, combined with the ultrasound appearances, suggested the diagnosis in the present case. When subdiaphragmatic pulmonary sequestration is suspected on ultrasound examination, confirmation may be obtained with ultra-DAVIES ET AL 49 sound-guided fine-needle biopsy, allowing conservative management while asymptomatic.…”

A case of pulmonary sequestration between the left hemidiaphragm and the left adrenal gland is reported, first detected at 16 weeks' gestation on routine prenatal ul· trasound examination. The echogenic rounded mass was again observed on ultrasound at 33 weeks' gestation. Postnatal ultrasound showed the mass adjacent to and compressing the left adrenal gland. Two weeks after birth, ultrasound*guided fine·needle aspiration biopsy was performed. Cytology showed respiratory epithelium and pulmonary sequestration was suggested; this was later confirmed surgically.The combination of ultrasound appearance and aspi· ration biopsy result can provide a diagnosis of infradiaphragmatic pulmonary sequestration, allowing conservative management while asymptomatic.The presence of extralobar sequestration should prompt detailed examination for further anomalies, which may be present in up to 60% of cases. These include diaphragmatic herniation and various congeni• tal abnormalities of the gastrointestinal tract. CASE REPORTRoutine ultrasound examination of a fetus at 16 weeks ges· tation showed an echogenic mass measuring 13 mm in diameter situated posteriorly in the region of the stomach (Fig. 1). A further ultrasound examination at 34 weeks' gestation confirmed the presence of a uniformly echogenic mass measuring 18 X 15 mm. This mas11 was situated posteriorly and, although the diaphragm was not visualized direct)~ the position of the mass in relation to the heart and bony structures suggested a subdiaphragmatic location. Cesarean section was performed at 37 weeks for severe preeclampsic toxemia. No abdominal man was palpable and there was no other abnormality on clinical examination.A follow-up ultrasound examination at 3 days of age showed a uniformly echogenic ovoid mass (approximately 2 em in diameter) situated posteriorly between the left kidney and the diaphragm, medial to the spleen (Fig. 2). The left adrenal gland was compressed and displaced inferiorly by the echogenic mass. On real-time examination a small, cylindrical echo-free structure was seen within the mass and was thought to represent a vascular structure.The differential diagnosis at this time included neuroblas· toma, a foregut duplication, and congenital teratoma or other adrenal tumor. A computed tomography (CT) examination of the upper abdomen showed no evidence of calcification associated with the mass. Laboratory investigations included uri· nary catecholamine estimation, alpha feto-protein, 8-HCG, androgen, cortisol, and 16-hydroxy-DHEA levels; all of which were within the normal range.A fine-needle aspiration biopsy was performed under gen~ eral anesthesia with real-time ultrasound guidance.

Introduction:Iliopsoas abscess (IPA) is a collection of pus in the iliopsoas compartment, which is considered rare in Japan. However, the number of patients with IPA has recently increased among the elderly or compromised hosts.Subjects and Methods:This retrospective study aims to examine the clinical pictures, pathological findings, and the prognostic factor of IPA. We analyzed all patients with IPA who were admitted to our hospital from April 2006 to July 2011. Patients’ characteristics, treatment, clinical outcome, radiological findings, bacteria isolated, and comorbidities were evaluated. The comorbidities were evaluated by the Charlson comorbidity index (CCI). We compared the survival and non-survival groups to assess the prognostic factors of IPA.Results:A total of 33 patients were enrolled in this study, which included 14 males and 19 females. The mean age of the patients was 71.5 years (range 32-92 years). The most common underlying disease was spinal disease (16 of 33, 48.5%). Twenty-nine patients (87.9%) were cured and four patients (12.1%) died. While 12 patients (36.4%) were initially treated conservatively with antibiotics alone, percutaneous drainage was performed initially in 19 patients (57.6%). Two patients (6%) directly underwent exploratory surgery and open drainage. In terms of patients’ characteristics, there were no significant differences in either group. The score of CCI in non-survivors was higher than that in survivors (1.38 vs. 5.5, P < 0.001).Conclusions:The epidemiology of IPA is quite different from what it used to be. CCI appears to be useful in evaluating the patients’ prognosis with IPA.

“…Imaging-guided percutaneous aspiration or drainage using sonographic guidance was first reported in 1974 in adults and now has been applied in children [6][7][8][9][10][11][12]. Tan et al [22] reported a series of six cases, three of whom were solitary abscesses that were treated by open drainage in two and antibiotics alone in one with good results.…”
