Thoracic and Diaphragmatic Endometriosis
Endometriosis is typically linked to painful periods and other gynecological symptoms.
Still, for a subset of patients, endometriosis lesions grow in or near the lungs – creating a confusing set of symptoms such as chest pain and coughing. Because thoracic endometriosis is potentially life-threatening, patients should seek professional treatment for this disease.
What is Thoracic Endometriosis?
Endometriosis is a frequently painful condition where tissue similar to the uterine lining (endometrium) grows outside the uterus.
Although endometriosis typically affects the pelvic area, sometimes endometriosis patches grow in extragenital locations. When the abnormal tissue grows in the thoracic cavity (the chest, including the diaphragm and lungs), it is referred to as thoracic endometriosis.
Because endometrial tissue swells and bleeds during menstrual cycles, thoracic endometriosis symptoms typically coincide with a patient’s menstrual period. Complications can include bleeding or a collapsed lung, and symptomatic thoracic endometriosis should be medically addressed.

What is Diaphragmatic Endometriosis?
Diaphragmatic endometriosis is a condition characterized by the presence of endometrial-like tissue on the diaphragm, which can lead to cyclical pain, discomfort, and respiratory issues.
Surgical interventions for this condition may involve minimally invasive techniques such as thoracoscopic surgery and robotic-assisted surgery. Both methods provide benefits, including shorter recovery times and reduced postoperative pain compared to traditional open surgery.
When addressing diaphragmatic fenestrations, it is typically advised not to suture them due to the potential incomplete removal of endometriosis tissue; instead, excision should be preferred. Experienced surgeons utilize a variety of techniques aimed at preserving as much muscle as possible from the diaphragm, thereby minimizing the risk of impaired function.
It is important to note that this type of surgery can result in significant postoperative discomfort, which often comprises a substantial portion of the recovery process. Our specialists, drawing from their extensive experience, will be able to guide you in understanding the possible ramifications of the procedure, including outlining effective strategies for managing discomfort. This comprehensive approach ensures that patients are well-informed about what to expect during the recovery period and the potential impact on diaphragm function.
The most common symptoms
Thoracic endometriosis is most often diaphragmatic (located on the diaphragm), but lesions can grow anywhere inside the thoracic cavity. Symptoms are generally due to health conditions that are caused by thoracic endometriosis. These are the most common conditions and symptoms associated with thoracic endometriosis (catamenial means they only occur during a person’s menstrual period):
Catamenial pneumothorax
A collapsed lung when air leaks into the space between the lungs and chest wall. (Symptoms: Chest pain, shoulder pain, cough, and shortness of breath)
Catamenial hemothorax
When blood accumulates within the lung lining or pleural space. (Symptoms: Chest pain, cough, and shortness of breath)
Catamenial hemoptysis
Bleeding in one or both lungs. (Symptoms: Coughing up blood, chest pain, and shortness of breath)
Pulmonary nodules
Atypical lung growths. (Symptoms: Chest pain, cough, and shortness of breath)
Thoracic endometriosis often coincides with pelvic endometriosis, so in addition to knowing the specific symptoms of thoracic endometriosis, patients should also be aware of the general symptoms of endometriosis.
Treating
The disease
Because thoracic endometriosis is potentially life-threatening, it should be treated by a qualified medical professional. Treatment for thoracic endometriosis typically involves a combination of minimally invasive surgery, hormonal therapy, NSAIDs, GnRH agonists, and/or alternative pain therapies.
Thoracic endometriosis frequently coexists with pelvic endometriosis, and the most effective surgical strategy aims to remove all abnormal tissue in a single procedure.
ESSI consists of surgeons with multi-organ expertise who, in selected cases, can excise endometriosis lesions in both areas without the need for a second surgeon. However, this may necessitate collaboration between a thoracic surgeon and an endometriosis specialist, depending on the surgeon’s skill level and the complexity of the operation.
Diagnosing
Thoracic Endometriosis
Magnetic resonance imaging (MRI) is typically used for the identification of thoracic endometriosis. It is essential that the MRI is conducted with a specific endometriosis protocol to enhance the detection of this condition.
Furthermore, the radiologist or surgeon interpreting the images should be an expert in endometriosis to ensure accurate diagnosis.
It is important to note that MRI negativity only rules out large lesions and significant diaphragmatic fenestrations; however, thoracic endometriosis is often thin and widespread, making it difficult to identify via MRI. Therefore, the gold standard for diagnosis remains surgical inspection via thoracoscopy and laparoscopy.
