“…Generally, mucinous appendiceal neoplasms are the leading cause of PMP; other sites are the ovaries, colon, urachus, and pancreas [ 8 ]. Adenomucinous neoplastic cells produce a large amount of mucus and, with progressive growth, eventually cause obstruction of the appendiceal lumen.…”

“…The ultrasonographic diagnosis is very difficult, it must be suspected, when ascitic fluid is highly echogenic, with immobile echogenic septations with a marked laminated appearance (the ‘onion-skin’ effect) that reflects the concentric layering of mucin, typical of viscous or gelatinous fluid [ 8 ]. The gold standard for imaging is CT, preferably with a contrast medium [ 1 ].…”

Pseudomyxoma peritonei (PMP) is a rare malignancy of the abdomen, which is usually described as a gelatinous peritoneal fluid. A 33-year-old man came to the ER complaining of recurring abdominal pain with abdominal distention for the past 3 months. Abdominal ultrasound revealed moderate amount of turbulent ascitic fluid with septations, in addition to a mass with irregular margins consisting of liquid and cysts. Abdomen and pelvis computed tomography scan showed free abdominal fluid. A decision was made for abdominal diagnostic laparoscopy with biopsies from the peritoneum, mesenteries and the gelatinous fluid. We could not investigate all the abdominal cavities and appendix due to the presence of severe adhesions and tuberculosis suspension. The pathology report indicated PMP. The patient was referred to an oncologist for chemotherapy consultation. The diagnosis can be challenging, as the symptoms and signs vary from patient to another; most cases may be asymptomatic and discovered incidentally during laparoscopy.

“…Ultrasound indicated that the mass in the left upper and middle abdomen was flocculent, with an internal stripe-like echo (Figure 2A ). The mass could not be deformed by the probe pressing technique[ 10 , 11 ]. The space occupying lesion looked like a mucinous mass, on the basis of the flocculent and stripe-like echoes observed in the scan.…”

BACKGROUND Pseudomyxoma peritonei (PMP) is a rare mucinous neoplasm with a relatively low incidence of 1 to 2 per million individuals. It is typically characterized by a type of gelatinous ascites named “jelly belly”. Most cases of PMP occur in association with ruptured primary mucinous tumors of the appendix (90%). Periodically, PMP can originate from mucinous carcinomas at other sites, including the colorectum, gallbladder, and pancreas. However, unusual origin can occur, as noted in this case report. CASE SUMMARY A 52-year-old woman had an unusual derivation of PMP from intestinal duplication. The patient complained of abdominal distension and increasing abdominal girth. Abdominal contrast-enhanced computed tomography showed a mass in the greater omentum located on the left side of the abdomen, likely to be a cystic mass of peritoneal origin. A PMP diagnosis was presumed based on the specific signs of the mass with flocculent and stripe-like echoes in ultrasound images. Ultrasound-guided percutaneous aspiration suggested a high likelihood of PMP. Once the PMP diagnosis was recognized, identification of the origin of the primary tumor was indicated. Thus, an exploratory laparoscopy was performed. In the absence of a primary tumor of appendix origin, the diagnosis of a low-grade mucinous neoplasm of intestinal duplication origin was finally confirmed by histopathology. CONCLUSION PMP is secondary to mucinous carcinomas of the appendix mostly. This case resulted from an unusual derivation from intestinal duplication.
