Ovarian Carcinoma Metastatic to Stomach and Duodenum
This is the case of a 50 year-old woman, presented with weight loss, nausea and vomiting, the endoscopy found a unusual image with multiple tiny yellowish nodules in the gastric fundus and duodenum, the wall of the duodenum were thickened, at the beginning one thought that it was a lymphoma, the biopsies shown a metastatic carcinoma, Immunohistochemical studies rule out a malignant melanoma and breast carcinoma, the mammography were negative as well as the physical examination to find any mass in both breast. Multiple lymph-node were palpable at the neck as well as supraclavicular lymphadenopathy. At the computer tomography cat scan showed mediastinal and para-aortic lymph-node enlarged, a large mass in the left ovary was detected, which were histologically identical and consistent with an ovarian primary neoplasia.
Gastric metastasis of ovarian cancer is extremely rare.

Involvement of the stomach by blood-borne metastatic malignancy in relatively uncommon. The primary neoplasms which most frequently metastasize to the stomach via the blood are malign melanoma and carcinoma of the breast.
Secondary neoplastic involvement of the stomach is most commonly the result of commonly the direct spread from a contiguous neoplasm such as carcinoma of the pancreas or non-contiguous tumor such as carcinoma of the transverse colon which may spread to the stomach via the gastrocolic ligament.
Gastric metastasis from breast cancer is uncommon and typically occurs in patients with disseminated disease. The vast majority of patients with gastric lesions have a known preexisting diagnosis of breast cancer.
Carcinoma of unknown primary (CUP) is defined as the histological diagnosis of metastasis without the detection of a primary tumor.

Ovarian cancer continues to pose a major challenge to physicians and radiologists. It is the leading cause of mortality from female genital tract malignancy. There are no established population-based screening programmes for the disease and few specific symptoms and signs of ovarian cancer. Consequently the majority of women present with advanced disease with poor prognosis. Survival in all cases at 1 year is 55% and at 5 years is 29%. Median survival is 14 months.
When faced with a woman with an ovarian mass the physician is required to make a judgement about the likelihood of malignancy. Following clinical assessment, ultrasound (US) and serum CA-125 estimation are the next investigations. Based on these three evaluations women can be divided into those with an ovarian mass and evidence of peritoneal spread.

The duodenal walls are thick
Ovarian tumors are derived from epithelial cells and occur in women between 40 and 65 years of age. Epithelial ovarian cancers commonly spread along the peritoneal surfaces by exfoliation of cells, and lymphatic dissemination to the pelvic and para-aortic nodes is noted in advanced disease. Hematogenous spread at diagnosis is rare, with only 2% to 3% of patients having lung or liver metastases.

Abdominal ultrasound shows para-aortic lymph-node adenopathy.
Ovarian cancer is the most common cause of cancer death from gynecologic tumors in the United States. Early disease causes minimal, nonspecific, or no symptoms. Therefore, most patients are diagnosed in an advanced stage. Overall, prognosis for these patients remains poor. Standard treatment involves aggressive debulking surgery followed by chemotherapy. Many histological types of ovarian tumors are described. However, more than 90% of malignant tumors are epithelial tumors.

Ultrasound shows an enlarged para-aortic lymph node
Ovarian carcinoma can spread by local extension, lymphatic invasion, intraperitoneal implantation, hematogenous dissemination, and transdiaphragmatic passage. Intraperitoneal dissemination is the most common and recognized characteristic of ovarian cancer. Malignant cells can implant anywhere in the peritoneal cavity but are more likely to implant in sites of stasis along the peritoneal fluid circulation. As discussed later, these mechanisms of dissemination represent the rationale to conduct surgical staging, debulking surgery, and intraperitoneal administration of chemotherapy. On the other hand, early hematogenous spread is clinically unusual, although it is not infrequent in patients with advanced disease.

Derrame pleural: Pleural Effusion, Hígado: Liver
Advanced ovarian cancer is the leading non-breast gynaecologic cause of malignant pleural effusion.
Cancer accounts for 40% of all pleural effusions, especially in patients over 50 years old. Bronchogenic and breast cancer account for 75% of malignant pleural effusions, with the remaining 25% represented by a cross-section of other neoplastic diseases.
Approximately two thirds of malignant pleural effusions occur in women because of the strong association with breast and ovarian cancer. Advanced ovarian cancer is the leading non-breast gynaecologic cause of malignant pleural effusion. Pleural metastases were found in 48% of women who died from ovarian cancer.

The general approach to managing malignant effusions is determined by symptoms, performance status of the patient, expected survival and response of the known primary tumor to systemic treatment. Intervention options range from observation in the case of asymptomatic effusions through simple thoracentesis to more invasive methods such as thoracoscopy, pleuroperitoneal shunting and pleurectomy. In patients with reasonable survival expectancy and good performance status every attempt should be made to prevent recurrence of the effusion. Intercostal tube drainage with instillation of a sclerosing agent, resulting in the obliteration of the pleural space, is the most widely used method to control recurrent symptomatic malignant pleural effusions.
Since malignant pleural effusions are frequently a preterminal event with a 30-day mortality rate of 29 to 50%, treatment is directed toward symptomatic relief with minimal discomfort, inconvenience and cost.

This image and the video clips shows no liver metastases
The disease is uncommon in patients younger than 40 years, after which incidence increases. Most cases are diagnosed in the seventh decade of life.
Malignant pleural effusions are caused most commonly by carcinomas of the breast, lung, gastrointestinal tract or ovary and by lymphomas. In male patients about half of malignant effusions are caused by lung cancer, 20% by lymphomas or leukemia, 7% from gastrointestinal primaries, 6% from genitourinary primaries, and 11% from tumors of unknown primary site. In female patients, about 40% of malignant effusions are caused by breast cancer, 20% from tumors arising in the female genital tract, 15% from lung primaries, 8% from lymphomas or leukemia, 4% from gastrointestinal tract primaries, 3% from melanoma, and 9% from tumors of unknown primary site. Effusions may be secondary to impaired pleural lymphatic drainage from mediastinal tumor (especially in lymphomas) and not due to direct pleural invasion.

Left Pleural Effusion
Local treatment options include repeated thoracenteses, chest tube drainage with sclerotherapy, pleuroperitoneal shunt or pleurectomy. Repeated thoracentesis is usually a temporizing measure and carries the risk for pneumothorax and pleural infection. Inpatient drainage with large-bore tubes (28–36 F) is effective, with variable 30-day success rates reported between 55% and 95%. For this reason, large-bore tube thoracostomy with sclerotherapy has become the most common palliative treatment for malignant effusions. It has to be mentioned that recent studies have shown that small drainage catheters (10 to 14 F) are as effective as large bore chest tubes in the treatment of malignant effusions. Using imaging guidance, small tubes can be placed into loculated collections, are well tolerated and have complication rates less than the larger tubes.

Meigs syndrome is defined as the co-existence of bening ovarian fibroma, hydrothorax and ascites. On the contrary, Pseudo-Meigs syndrome is characterized by the co-existence of hydrothorax, ascites and other ovarian- usually malignant-or pelvic tumors.
The co-existence of pelvic tumor, hydrothorax and ascites has been known since the late 19th century. The features of the disease were described by Meigs and Cass in 1937. In the same year Roads named it “Meigs syndrome”. Today, Meigs syndrome is defined as the co-existence of bening ovarian fibroma, hydrothorax and ascites. On the contrary, Pseudo-Meigs syndrome is characterized by the co-existence of hydrothorax, ascites and other ovarian- usually malignant-or pelvic tumors. Both these syndromes should be considered in otherwise healthy postmenopausal women, who present with either new or recurrent hydrothorax and ascites. The preoperative differential diagnosis between them is useless, since the surgical resection of the tumor is the only therapeutic choice, resulting to the resolution of fluid accumulations in both situations
