This is the second case that demonstrates lymphovascular invasion of the tumour and the third that exhibits its malignant potential. We present a case of a 69-year-old woman with a large palpable abdominal mass that was thought to arise from the ovary following a staging CT scan. Intraoperatively, a large ovoid mass measuring 18\u2005cm\u00d715\u2005cm\u00d711.5\u2005cm was found on the small bowel mesentery. Histological examination revealed the characteristic Zellbalen pattern with lymphovascular involvement. Mesenteric paraganglioma is rare and remains a diagnostic dilemma. Although the majority of paragangliomas are non-functional and do not show any malignant potential, individual case-based management is needed in view of their unpredictable nature. A multidisciplinary approach with genetic counselling and long-term follow-up are usually necessary to monitor for future disease recurrence.<\/jats:p>","DOI":"10.1136\/bcr-2015-209601","type":"journal-article","created":{"date-parts":[[2015,5,12]],"date-time":"2015-05-12T14:50:08Z","timestamp":1431442208000},"page":"bcr2015209601","update-policy":"https:\/\/doi.org\/10.1136\/crossmarkpolicy","source":"Crossref","is-referenced-by-count":3,"title":["A large mesenteric paraganglioma with lymphovascular invasion"],"prefix":"10.1136","volume":"2015","author":[{"given":"Mohd Afiq","family":"Mohd Slim","sequence":"first","affiliation":[],"role":[{"role":"author","vocabulary":"crossref"}]},{"given":"Susan","family":"Yoong","sequence":"additional","affiliation":[],"role":[{"role":"author","vocabulary":"crossref"}]},{"given":"William","family":"Wallace","sequence":"additional","affiliation":[],"role":[{"role":"author","vocabulary":"crossref"}]},{"given":"Keith","family":"Gardiner","sequence":"additional","affiliation":[],"role":[{"role":"author","vocabulary":"crossref"}]}],"member":"239","published-online":{"date-parts":[[2015,5,12]]},"reference":[{"key":"2025042706171249000_2015.may12_1.bcr2015209601.1","doi-asserted-by":"publisher","DOI":"10.1210\/jc.2014-1498"},{"key":"2025042706171249000_2015.may12_1.bcr2015209601.2","doi-asserted-by":"publisher","DOI":"10.1016\/S0140-6736(05)67139-5"},{"key":"2025042706171249000_2015.may12_1.bcr2015209601.3","unstructured":"DeLellis R , Lloyd R , Heitz P , et al .
