Approximately 80% of ovarian cancers are discovered when they have already progressed to stage III or IV lesions. The prognosis is, therefore, poor despite intensive treatment. Intraperitoneal dissemination is one of the most frequent pathways of distant spread ovarian cancer and pseudocystic metastases usually occur. When such cystic metastases remain symptomatic despite antitumor treatment, viable options are limited because palliative surgery generates high operative morbidity and mortality. For many years, in patients in whom the risks associated with surgery are high, percutaneous drainage and sclerosis under radiologic guidance has been performed as an effective alternative option for various forms of abdominal fluid collection. Such a collection in pancreatic pseudocyst benefits from cystogastric transmural drainage to avoid external drainage and achieves the same results as surgical cystogastrostomy. We report this transmural drainage technique under image guidance used to drain a symptomatic cystic metastasis, which was compressing the stomach.
