RESUMO
Pseudomyxoma peritonei (PMP) is a rare clinical condition characterized by disseminating gelatinous ascites within the peritoneal cavity with mucinous implants on peritoneal surfaces. We present the case of a patient incidentally diagnosed after laparoscopy: definitive diagnosis after the histological examination was PMP. A 37-year-old female patient with a medical history of infertility and mild pelvic pain was found to have several collections in the pelvis and an amount of free fluid into the Douglas pouch at ultrasound examination. The patient underwent laparoscopic surgical exploration. Peritoneal biopsies and appendectomy were performed. Histological examination was about a low-grade appendiceal mucinous tumor limited to the mucosa without submucosal infiltration with perforation of the wall and deposit of periappendicular acellular mucin. The patient was discharged in good health and referred to an oncological peritoneal center where cytoreductive surgery (CRS) and hyperthermic intraperitoneal chemotherapy (HIPEC) were performed. In conclusion, PMP is an uncommon disease within the abdomen, characterized by a mucinous tumor that produces progressive mucinous ascites. It is characterized by various non-specific symptoms and signs and difficult imaging diagnoses. Histological diagnosis is a determinant to establish the therapy that can differ significantly, depending on the stage of the disease.
RESUMO
Fertility preservation is an integral component of clinical decision-making and treatment design. However, the selection criteria on imaging for patients eligible for fertility preservation is still unclear. The present review aimed to summarize the main findings reported in both the literature and international guidelines on the role of imaging in the selection of patients for fertility preservation. A search strategy was developed and applied to PubMed, Scopus, Web of Science, and EMBASE to identify previous citations reporting imaging and fertility preservation in patients with gynecological cancer. We also retrieved the published guidelines on the eligibility criteria for fertility-sparing treatment of gynecological neoplasms. A description of the internal multidisciplinary guidelines, clinically in use in our institution, is provided with representative clinical cases. The literature review revealed 1291 articles and 18 of these were selected for the analysis. Both ultrasound and MRI represented the primary imaging methods for selecting patients for fertility preservation in cervical and endometrial cancers. Eligibility criteria of fertility-sparing management in patients with cervical cancer were: tumor size <2 cm, tumor distance from the internal os >1 cm, and no parametrium invasion. For patients with endometrial cancer, these included no myometrial and cervical stroma invasion. Both ultrasound and MRI play a key role in characterizing adnexal masses. These modalities provide a useful tool in identifying small ovarian lesions, thus key in the surveillance of patients after fertility sparing surgery. However, efficacy in excluding disease beyond the ovary remains limited. This review provides an update of the literature and schematic outline for the counseling and management of patients with the desire for fertility preservation.
