Mesenteric inflammatory pseudotumor: a case report and comprehensive literature review

Abstract

Purpose: This study aims to provide an overview of the literature on mesenteric/omental inflammatory pseudotumors (IPTs).

Methodology: We present a new case of mesenteric IPT. We also conducted a systematic search of the English-language medical literature using PubMed, Medline, Google, and Google Scholar related to mesenteric or omental IPTs. The following search terms were used in various combinations: inflammatory myofibroblastic tumor, IPT, mesentery, and omentum. The search included articles published in the English language between January, 1978 and April, 2014. Studies were excluded if the full text was unavailable or missing information prohibited comparisons.

Results: A total of 30 reports concerning 36 patients with inflammatory pseudotumors meeting the aforementioned criteria were included. The patients were aged from 10 months to 68 years (mean, 19.98 ± 20.5 years); 12 were female (16.75 ± 16.97 years; range, 10 months to 68 years) and 24 were male (21.6 ± 21.9 years; range, 18 months to 63 years). Detailed clinical and pathologic characteristics of 36 patients with IPTs are provided in Table 1.

Conclusion: IPTs may be definitively diagnosed only by histopathological examination and are most effectively treated by resection with negative surgical borders. No consensus has yet been reached regarding when nonsurgical treatment options are most appropriate in management of these lesions. IPTs often recur locally, while distant metastases are very rare. Postoperative close surveillance is essential to detect recurrences early.
