Mesenteric root pseudocyst: finding in an asymptomatic patient—a case report

Mesenteric cysts are one of the rarest abdominal tumor masses, representing a little-studied pathology. In turn, the variability and non-specificity of clinical manifestations make diagnosis difficult, as it can be reached by imaging findings due to another cause or by non-specific abdominal pain.

This article describes the case report of an asymptomatic 28-year-old patient who presented a 6-cm abdominal cystic mass with mixed density, which was found incidentally by computed tomography. Exploratory laparoscopy was performed followed by conversion to conventional surgery to extract the tumor mass. The anatomical pathology diagnosis was pseudocyst of the mesentery root. Mesenteric cysts are one of the rarest abdominal tumor masses, representing a little-studied pathology. In turn, the variability and non-specificity of clinical manifestations make diagnosis difficult, as it can be reached by imaging findings due to another cause or by non-specific abdominal pain.

Mesenteric cysts are rare, and their nonspecific symptoms often lead to diagnosis based on imaging findings. Complete laparoscopic enucleation is the standard treatment.
