Ultrasound guided fine needle aspiration biopsy of splenic lesions.
Fine needle aspiration biopsy (FNAB) of focal splenic lesions has been infrequently utilized because of the risk of haemorrhage. This study was carried out to evaluate the safety and efficacy of ultrasound guided FNAB of splenic lesions. 35 patients with focal splenic lesions underwent FNAB under real-time ultrasound guidance using a free hand technique. Ultrasound findings were single or multiple focal hypoechoic lesions (n = 33), focal hyperechoic lesion (n = 1) and diffuse heterogeneous echotexture (n = 1). Aspirations were performed with 22 G spinal needles using either the subcostal or the intercostal approach. Definite cytological diagnosis was made in 22 patients (62.8%), including tuberculosis in 10 patients, lymphoma in seven patients, extramedullary haematopoiesis in two patients and aspergillosis, histoplasmosis and bacterial abscess in one patient each. FNAB was negative in 12 patients because the aspirates were either scanty or contained only blood. FNAB was falsely positive in one patient. Only one patient had significant intraabdominal bleeding, which was managed conservatively. In conclusion, splenic FNAB performed under ultrasound guidance is a safe and accurate method in the diagnosis of focal splenic lesions.
