Can ovarian cyst cause pleural effusion?
Meigs syndrome is defined as the triad of benign ovarian tumor with ascites and pleural effusion that resolves after resection of the tumor. Ovarian fibromas constitute the majority of the benign tumors seen in Meigs syndrome.
What does an ovarian fibroma look like?
It is composed of spindle cells forming variable amounts of collagen. Sectioning of a fibroma typically reveals a chalky-white surface that has a whorled appearance, similar to that of a uterine fibroid. Areas of edema, occasionally with cyst formation, are also relatively common.
Why is there right sided pleural effusion in Meigs syndrome?
Exudative effusion in patients with Meigs’ syndrome seems to be consistent with the mechanisms involved in pleural fluid accumulation. It is believed that the direct cause of pleural fluid formation is the translocation of ascites via diaphragmatic pores.
Which tumor is associated with Meigs syndrome?
The syndrome as originally described by Meigs was limited to fibroma of the ovary. Recently he redefined this syndrome and included thecomas, granulosa-cell tumors, and Brenner tumors. These, according to Meigs, are the tumors with which this syndrome is most commonly associated.
Are most ovarian tumors benign?
Ovarian tumors are most often benign, however, some types may develop into ovarian cancer if left untreated. Symptoms are rare and tumors are usually detected during a routine pelvic exam or Pap test. Treatment typically involves surgical removal of the tumor and sometimes the surrounding tissue or the affected ovary.
Are ovarian fibromas common?
An ovarian fibroma is a rare, benign tumor of the ovary. Most commonly found in women in their 50s during perimenopause (transition to menopause) or postmenopause, ovarian fibromas account for approximately four percent of all ovarian tumors.
Does ovarian tumor cause ascites?
Local secretion of vascular endothelial growth factor (VEGF) is a key factor in both tumor growth and ascites formation (5). 38% of malignant ascites occurring in women are associated with ovarian cancer. During the course of the disease, more than one-third of women with ovarian cancer will develop ascites (3).
Can a benign ovarian tumor cause ascites?
This is not unusual in that various types of benign to highly malignant ovarian tumors may present as massive ascites of unknown origin.
How do you know if pleural effusion is malignant?
Cytology/lymphocyte subsets – Pleural fluid cytology, a quick and easy method of obtaining material for analysis, can potentially confirm the diagnosis of malignant pleural effusion by identification of malignant cells. Sixty percent of MPE will have positive cytology, although this figure is lower in mesothelioma.
What percentage of ovarian fibromas are associated with pleural effusions?
They are associated with ascites in 40% of cases and with pleural effusions in a small percentage of cases. Meigs syndrome: consists of ovarian fibroma with ascites and a pleural effusion
How are fibromas diagnosed in lung cancer?
These tumors are often an unexpected finding on transvaginal ultrasound, computer tomography or magnetic resonance imaging performed for various reasons. However, symptoms related to ascites and pleural effusion may develop, especially in those cases with large tumors. Fibromas are rarely bilateral (5% of cases).
What are fibromas on ultrasound and CT?
On ultrasound, fibromas most commonly manifest as solid, hypoechoic masses with ultrasound beam attenuation. As such, they may appear similar to a pedunculated subserosal uterine fibroid. However, the sonographic appearance can be variable, and some tumors can rarely have cystic components. CT
What ultrasound findings are characteristic of pleural effusion?
In some cases, ultrasound images other than those of the effusion can help assess the nature of the pleural effusion. For example, the presence of thickened pleura or of a pulmonary consolidation with dynamic air bronchogram (suggestive of an infectious origin) is usually indicative of an exudate.
