 Case Report

A 38-year-old male presented with lower abdominal mass and left-sided hydrocele following short period of irregular fever. General examination was non-contribu­tory. Abdominal examination revealed a non-tender, firm mass about 5 cm x 5 cm in size in the left iliac fossa and hypogastric region, fixed to the posterior abdominal wall. There was left-sided hyrocele with thickened epididymis but no lymphedema. Hematological and biochemical pa­rameters were within normal limits. CTs of the abdomen showed a heterogeneous mass of size 5.5 cm x 5.3 cm anterior to left psoas muscle and common iliac vessels partially compressing the left ureter causing left-sided hydroureter and hydronephrosis. Rt. kidney, ureter and both testicles were normal [Figure 1]. A diagnosis of retro­peritoneal tumour was made. FNAC of abdominal lump showed microfilaria of W. bancrofti along with an assorted population of lymphocytes, neutrophils and histiocytes [Figure 2]. The patient was treated with Amoxycillin and Die­thyl Carbamazine in adequate doses. The abdominal lump subsided and CT showed almost complete resolution of the mass with normal left kidney and ureter [Figure 3]. The hydrocele regressed with little residual fluid.


98% of filariasis, a common helminthic infestation in India is caused by Wuchereria bancrofti. [1] In occult filariasis there is no classical clinical manifestations like lymphe­dema or microfilaremia. The larvae reside in the internal organs or tissues. Mehta et al [2] reported a filarial abscess in their study of retroperitoneal tumorous lesions. Gupta et al [3] diagnosed an infected retroperitoneal cyst to be of filarial origin by aspiration cytology and treated it surgically. In the present case there was no classical manifesta­tions of filariasis or microfilaremia, FNAC of abdominal mass revealed microfilaria. Administrations of antifilarial drugs caused resolution of the mass and recession of ob­structive uropathy.
