I’ve read bits and pieces here and there that Endometriosis can grow on or inside of your lungs. An EndoSister had posted in one of the many Facebook support groups that I follow that she has Endo on her lungs, which causes her to cough up a lot of blood. Others replied that they have it as well, but it leaves them in the hospital with collapsed lungs every month. Which got my juices flowin’ to find the documented cases of Endometriosis on the lungs, how it was excised (if at all), etc. Here goes! This is NOT meant to scare you. Just educate us all, including myself.
Endometriosis is usually found within the pelvic cavity, but has also been known to be found northward and latching onto the liver and diaphragm. It has also been found on the membranes surrounding the lungs and heart. Even rarer, it has been found on the brain, in the lymph nodes, and on the eyes.
Thoracic or Pulmonary Endometriosis is when Endometriosis implants/adhesions are found in your thoracic region, and can be found on your trachea, bronchi, diaphragm, lungs, or heart. It was first medically documented in 1953. Today, we focus on the lungs.
This CAN be fatal. If you suffer from these symptoms, or suffer from recurrent lung collapses, seek emergency medical attention. If you suspect you may have thoracic Endometriosis, please, I urge you to have a talk with your physician.
75% of women who have pulmonary Endometriosis suffer from catamenial pneumothorax, which can cause her lung(s) to collapse during her menstrual cycle (usually starts within 72 hours of her menstrual cycle beginning). Endometrial cells have implanted themselves along the lining of the lungs and when menstruating may cause air and blood to enter the lungs improperly, causing a collapse. Symptoms include stabbing pain, shortness of breath, dizziness, fatigue, neck pain, and a “pop” or “cracking” sensation. And, yet, some women have absolutely NO symptoms and it’s discovered by accident during surgery. It’s most common among 30-40 year old women with Endometriosis.
A 31-year-old woman had a prior medical history of iron deficiency anemia and several months of acute bronchitis went to the ER due to shortness of breath that had been progressively worsening. A chest x-ray showed her right lung had collapsed and filled with fluid. They drained her lung with a chest tube, but due to complications nearly two weeks later, she returned for VATS surgery. During the surgery, endometrial lesions were found along the lobes of her right lung, which were removed. At the time this publication was written, she had one period since surgery, with no recurrence of the collapsed lung; however, she did complain of right-sided chest pain during her period. She had since started oral contraceptives.
A 32-year-old woman had chest pain and shortness of breath for the past two months. Now with the onset of right abdominal pain for two days, she was admitted into the hospital. An ultrasound showed an endometrioma and fibroids. A chest x-ray showed a collapsed right lung. She received a chest tube and fluid was drained. Prior to being discharged from the hospital, the fibroids and endometrioma were surgically removed, and she hadn’t had any recurrence of symptoms two months later.
A 35-year-old woman with a history of a prior lung collapse went to the emergency room because she was having chest pain and shortness of breath. She had a known history of Endometriosis and infertility, as well as a collapsed lung two years prior. She was not on her period. It was discovered that she had a collapsed right lung and was sent in for VATS surgery. Bluish-brown lesions were found her her pleura and diaphragm, which were all resected, removed, biopsied, and confirmed to be Endometriosis. As of one year later, she had not had any recurrence.
A 36-year-old woman had gone to the emergency room because of abdominal pain, chest pain, shortness of breath and feeling faint. It was the second day of her period. She had a long-standing history of anemia, infertility, and a surgical Endometriosis diagnosis. The ER did some imaging studies, found fluid in her pleural cavity, and drained it – taking one litre of fluid! She also had some fluid in her abdomen. While at the ER, she collapsed and was rushed to surgery – they found blood clots in her pleural cavity, as well as suspected Endometriosis inside her lungs and on her diaphragm. They observed the blood was slowly leaking from the lesions…the lesions were cauterized (boo) and a portion of her lungs was resected. Biopsy confirmed Endometriosis and three months after her surgery, she still had not had a repeat collapse. She was referred to a gynecologist for future care.
A 43-year-old woman who had had ablation surgery for Endometriosis several years and who took Provera woke up one night due to sudden pain in the right side of her chest. Three hours later she was having trouble breathing. So she sought medical care. She was found to have fluid buildup along her right lung, which was drained via a needle procedure. A day later, she started her period and six days later underwent VATS surgery to remove a hematoma and more fluid buildup. The biopsy of tissues revealed chronic inflammation.
A 47-year-old woman went to the ER complaining of right flank pain, dizziness, and sweating. Testing showed she had fluid in lining of her lungs and she underwent VATS surgery. Tissue that was removed was biopsied and found to be Endometriosis. After surgery, she went on hormonal suppression (didn’t disclose if birth control or other) and has not had a recurrence of symptoms.
A 20-year-old woman went to a clinic because she had been coughing up blood. A month later, it happened again and she went to the hospital. A month later, again. Two weeks after her period, she was admitted for further studies, but her symptoms had ceased. Two years prior, she had undergone an abortion and had since taken contraceptive pills – then her coughing started about a month after she stopped taking the pill. Birth control pills were once more prescribed to her, but she did not take them and continued to cough up blood. Six months after her initial clinical visit, she underwent surgery and the biopsied tissue from her lungs tested positive as Endometriosis. While inside, her surgeons also found blood within her lungs. They removed what they could and she was symptom free at least four months after her surgery, without going back on the pill.
Not all women who have catamenial pneunothorax (lung collapses on their period) suffer from Endometriosis in/on their lungs. A study published in the December 2016 issue of Current Thoracic Surgery found one woman who had recurrent lung collapses on her period, and subsequent surgeries for those collapses, did NOT have Endometriosis. She just had collapses during her cycle. She was placed on birth control and it helped stop the collapses. Not everything is Endo…Just one more reason why conversations with your doctors and thorough medical histories are so important.
10.7% of women who have pulmonary Endometriosis suffer from catamenial hemothorax and/or hemopneumothorax, which is a build up of blood (and sometimes air) in the pleural cavity , which is the space between our lungs and our chest cavity. During a menstrual cycle, that inflammation and blood of the Endo implants cause pressure on the lungs, which can lead to shortness of breath, chest pain, clammy skin, low blood pressure, and rapid heartbeat.
8.5% of women who have pulmonary Endometriosis suffer from catamenial hemoptysis. This is when the Endometriosis implants/adhesions are found on the lung or lung nodules. This may cause the woman to cough up blood during her menstrual cycle, as well as cause back pain, a “bubbling sensation” in her chest, fatigue, and may obscure lung imaging studies during her menstrual cycle.
How does the Endometriosis get into the thoracic cavity and onto the lungs? Unfortunately, there are only theories: it spreads through the uterine veins into the venous system, it travels through the lymphatic system, we’re born with it there already, the prostaglandin (hormones) damage the lungs and pleural wall, it travels via the air circulated through the fallopian tubes, there are defects (holes) in a diaphragm which may allow the passage of these cells. The theories go on and on.
Regardless of how it actually gets to the lungs, many believe that the recurrent hormonal changes that the implants go through during a woman’s cycle may weaken the lung lining, or the lungs themselves, causing the pneumothorax and these issues to occur.
How is it diagnosed? Diagnoses may be delayed, and has been known to take as long as 8 months or more from the onset of symptoms until diagnosis. Imaging studies may rule out infection or malignancies, and may be helpful in supporting the suspicions of pulmonary Endometriosis. Just as surgery is the “golden standard” for diagnosing pelvic Endometriosis, VATS (video-assisted thoracoscopic surgery) is the “golden standard” for diagnosing thoracic Endometriosis. Some physicians may opt to perform a thoracoscopic and laparoscopic surgery at the same time to search the pelvic and thoracic cavities for Endometriosis.
But how is it removed? A procedure called a thoracoscopy is performed, and is very similar to a robotic laparoscopy. Small incisions are cut along the right of left sides of your upper torso, rather than your stomach. The little tiny instruments many of us EndoSisters have become familiar with are used in detecting, destroying, or excising Endometriosis in the thoracic cavity. Portions of the lung may also be removed/resected for biopsy. Drainage tubes may be present after surgery and remain during the healing process.
And treatment? It appears that thoracic Endometriosis and pelvic Endometriosis share the same treatment: hormones. It is believed that it is estrogen dependent. So Danzanol, progesterone, oral contraceptives, or GnRH treatments are used. Horrifyingly, I’ve read today that hysterectomies or removing the ovaries “is the treatment of last resort…” Can you imagine? Removing your lady bits for something that’s infected your lungs. I cannot. The horror. Especially when there has been no proof that a hysterectomy fully relieves your Endometriosis symptoms…Horror. In 2005, a 43-year-old woman received a hysterectomy, only to suffer a bilateral lung collapse in 2011. A thoracoscopy was then performed and Endometriosis implants were discovered and removed from her lungs and diaphragm. Again, I say : a hysterectomy is not a cure.
And one more thing we already knew: there is no cure. Whether it be on your lungs, your uterus, your bowels, your urinary tract, your diaphragm, your ovaries, or anywhere else it decides to sprout : there is no cure. But there will always be hope. And we are all in this together, regardless of the location of our Endo.
