Summary
A rare mesenteric pseudocyst caused acute abdominal pain in a 31-year-old woman. Surgical excision was successful, with the etiology suspected to be inflammation-induced lymphatic damage.
Area of Science:
- Gastroenterology
- Surgical Pathology
- Abdominal Imaging
Background:
- Mesenteric pseudocysts are rare intra-abdominal cystic masses.
- They can present with non-specific symptoms, mimicking other acute abdominal conditions.
Observation:
- A 31-year-old woman presented with right lower abdominal pain and tenderness.
- Initial imaging suggested an ovarian cyst, but laparotomy revealed a subserosal sigmoid colon mass.
- The mass was a 10 cm multilocular cyst containing gelatinous fluid.
Findings:
- Histological examination revealed a cyst wall composed of inflammatory cells and fibroblasts, lacking specific endothelial lining.
- The final diagnosis was a mesenteric pseudocyst, a condition rarely reported in the Japanese literature.
- The etiology remained unknown, but lymphatic injury due to inflammation was suspected.
Implications:
- This case highlights the diagnostic challenges posed by mesenteric pseudocysts.
- Prompt surgical intervention is crucial for managing symptomatic pseudocysts.
- Further research into the etiology of mesenteric pseudocysts is warranted.
