 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.
