The SpaceOAR Vue hydrogel system was developed to reduce the toxicity to the rectum following radiation therapy for prostate cancer. Initial trial data reported the product as overall effective and safe. However, a few additional observed complications have likely been brought on by its increased utilization. The case presented herein describes rectal erosion, with abscess and rectal fistula formation, associated with the use of the SpaceOAR Vue hydrogel system. The SpaceOAR Vue hydrogel system was subsequently found to be absent between radiotherapy treatments and was thought to have been passed rectally through the fistula. The benefits and complications of the SpaceOAR Vue hydrogel system are discussed, as well as key factors to consider as the recommendation of routine use increases. [ABSTRACT FROM AUTHOR]

Ectopic splenic tissue can be classified as accessory spleen, polysplenia or a phenomenon termed as splenosis. Once believed a rare occurrence, the incidence of splenosis is now thought to be significantly higher. Generally, splenosis is asymptomatic and discovered incidentally during operation, imaging or at autopsy. The case presented herein describes an incidental finding of an intraabdominal splenosis, which was subsequently biopsied to investigate for peritoneal metastatic disease. The biopsied tissue subsequently caused significant post-operative haemorrhage. Past medical history and specific pre-operative imaging modalities for patients presenting with asymptomatic peritoneal or intra-abdominal nodules are discussed. Splenosis is highlighted as a common condition to consider prior to invasive investigations. [ABSTRACT FROM AUTHOR]
