This revealed a swollen ileocecal valve associated with superficial ulceration (Figure 1).
(a) 40x H&E ileocecal valve showed moderate lymphocytic cell infiltrates in the mucosa together with cross sections of an adult female nematode. (b) 200x H&E ileocecal valve showed moderate lymphocytic cell infiltrates in the mucosa together with cross sections of an adult female nematode.

Histopathological examination of the biopsied tissue from the ileocecal valve showed moderate lymphocytic cell infiltrates in the mucosa together with cross sections of an adult female nematode (Figure 2).
400x H&E Cross section of the worm body wall displayed cuticle with prominent annulations, hypodermis with hypodermal nuclei, contractile portion muscle, and sarcoplasmic portion of muscle with nuclei.
