Intestinal Pseudo-Obstruction After Vincristine Use.

A 73-year-old man presented with nausea, abdominal discomfort, and distention persisting for the past five days. He had previously been diagnosed with stage III peripheral CD4+ T cell lymphoma and had initiated chemotherapy comprising vincristine two weeks prior to presentation. An evaluation revealed diffuse colon distention and pneumatosis intestinalis without mechanical obstruction, consistent with acute colonic pseudo-obstruction. The patient underwent surgical intervention and was subsequently admitted to the Intensive Care Unit due to distributive shock. Vincristine-induced ileus followed by intestinal pseudo-obstruction was suspected to be the underlying cause after excluding alternative causative factors.
