Lymphangiogram of a case of presumed lymphatic filariasis with left-sided cisterna chyli.

Lymphatic filariasis is an uncommon condition in Hong Kong and is currently considered as one of the neglected tropical diseases by the World Health Organization. Blood tests are available for diagnosis of acute infections, but false negative results can occur with chronic manifestations of lymphatic filariasis. We present a case which illustrates how radiological imaging can help with diagnosis of lymphatic filariasis.

Management of acute intra-abdominal hemorrhage in ruptured hepatoblastoma with transarterial embolization using calibrated gelfoam particles.

This brief report aims to evaluate the treatment outcome of transarterial embolization in ruptured hepatoblastoma complicated with acute intra-abdominal hemorrhage. Three children (mean age 6 years) with high-risk hepatoblastoma presented with rupture and acute intra-abdominal hemorrhage. In addition to aggressive fluid resuscitation and blood product support, super-selective embolization of the arteries with active bleeding or pseudoaneurysm was performed using calibrated gelfoam particles, with a technical success rate of 100%.

Percutaneous ultrasound-guided renal biopsies in a paediatric population: comparison of coaxial and non-coaxial techniques using 18-gauge core biopsy needles.

Background: Percutaneous ultrasound-guided biopsy is performed in paediatric patients for evaluation of diffuse renal parenchymal disease. When compared with the non-coaxial technique, the coaxial technique has the advantages of obtaining multiple tissue cores via a single capsular puncture and post-biopsy tract embolisation.

Objectives: To compare the coaxial and non-coaxial techniques of percutaneous ultrasound (US)-guided biopsy of native kidney parenchyma in children and adolescents with renal disease.
