A 45-year-old woman presents with RLQ pain. A CT scan is performed. What finding on CT scan is most suggestive of appendiceal lymphoma?a. Appendiceal diameter >2.5 cm or surrounding soft tissue thickening
Lymphoma of the appendix is uncommon. The most common types of appendiceal lymphoma in decreasing order are non-Hodgkin, Burkitt, and leukemia. Findings on CT scan include appendiceal diameter of >2.5 cm or surrounding soft tissue thickening. The management is confined to appendectomy. Right hemicolectomy is indicated if the tumor extends beyond the appendix onto the cecum or into the mesentery. If requiring a right hemicolectomy, postoperatively the patient will require a staging workup and possible adjuvant chemotherapy.
