To evaluate the feasibility, the risks and the efficiency of percutaneous image-guided core needle biopsy in children.

Ninety one percutaneous biopsies were performed in ninety children aged 3 to 16 years with a suspected haematological malignancy. A coaxial system allowed multisampling using 14 to 20 Gauge needles. We recorded the cause of referral, the location, type and size of the target lesion, the method used for needle guidance, the type of analgesia, the number and size of samples, the complications, and the final histologic diagnoses.

Eighty-one lymphnodes and nine masses were biopsied. Seventy superficial lesions were biopsied under ultrasound guidance. The remaining 20 lesions located in the retroperitoneum or mediastinum were biopsied under CT guidance. The mean size of the lesions was 26 mm (extremes 6-50). Biopsies diagnosed 30 Hodgkin’s lymphomas, 12 non-hodgkin lymphomas, 2 acute lymphoblastic leukemias, 22 inflammatory deseases, 5 normal lymph nodes, 12 lesions classified as « other ». Six biopsies were non conclusive. A small hematoma was the only complication. General anesthesia was required in only 4 cases.

Percutaneous image-guided biopsies are safe and efficient in children regardless of target site or needle size used. This simple and minimally invasive technique has become the method of choice for tissue sampling and does not need general anesthesia in most cases. Ultrasound-guidance is more frequently used in our institution because target lesions are often superficial and procedure can be done on an outpatient basis.

Percutaneous image-guided biopsies is simple and minimally invasive. It has become the method of choice for tissue sampling and does not need general anesthesia in most cases.
