A 62-year-old man probably wasn’t expecting to carry a monstrous mass located in his abdomen for 20 years.
The unnamed patient suffered from urinary frequency, but lab findings didn’t show anything. Then, doctors at the Washington, D.C. VA Medical Center discovered a large, egg-like mass in his abdomen.
Described in The New England Journal of Medicine as a “free-floating, smooth, firm, rubbery mass measuring 10 cm by 9.5 cm by 7.5 cm and weighing 220 g”, this giant ‘boiled egg’ managed to avoid detection through both physical examination and laboratory analysis, but was successfully detected through a computed tomography scan of the patient’s abdomen and pelvis.
As researcher Dr. Rachael Sussman of Georgetown University Hospital, told Fox News, the mass was identified as a peritoneal loose body, which occurs when small pieces of fat in the abdomen were detach from the surrounding structures. The fat calcified and turned into a fibrotic mass, which is completely benign.
Small peritoneal bodies are quite common, but this is the largest reported one in the literature to date,” Sussman said.
Most periotonal bodies are so small that they do not cause symptoms, but when they become large enough, they have been reported to cause small bowel obstruction and urinary retention.
The good thing was that, immediately after the surgical removal of the mass, the patient’s urinary frequency was then resolved.
According to researchers, this is the first case to report urinary frequency as a symptom. The patient had no other side effects from the mass, which compressed his bladder and after removing the mass, researchers used green ink to delineate its makeup of proteinaceous material with fibrinoid necrosis, surrounded by a ring of calcification.
