Catamenial pneumothorax

Thoracic Endometriosis: A Review Comparing 480 Patients Based on Catamenial and Noncatamenial Symptoms

OBJECTIVE

This review aimed to categorize thoracic endometriosis syndrome (TES) according to whether the presenting symptoms were catamenial and to evaluate whether such a categorization enables a better management strategy.

DATA SOURCES

An electronic search was conducted using the PubMed/Medline database.

METHODS OF STUDY SELECTION

The following keywords were used in combination with the Boolean operators AND OR: "thoracic endometriosis syndrome," "thoracic endometriosis," "diaphragm endometriosis," and "catamenial pneumothorax."

TABULATION, INTEGRATION, AND RESULTS

The initial search yielded 445 articles. Articles in non-English languages, those whose full texts were unavailable, and those that did not present the symptomatology clearly were further excluded. After these exclusions, the review included 240 articles and 480 patients: 61 patients in the noncatamenial group and 419 patients in the catamenial group. The groups differed significantly in presenting symptoms, surgical treatment techniques, and observed localization of endometriotic loci (p <.05).

CONCLUSION

This review points out the significant differences between patients with TES with catamenial and noncatamenial symptoms. Such categorization and awareness by clinicians of these differences among patients with TES can be helpful in designing a management strategy. When constructing management guidelines, these differences between patients with catamenial and noncatamenial symptoms should be taken into consideration.

Circulating Endometrial Cells in Women With Spontaneous Pneumothorax

BACKGROUND

The occurrence of catamenial pneumothorax (CP) is rare, and the awareness of this diagnosis among physicians is insufficient. CP is highly correlated with pelvic endometriosis and remains the most common form of thoracic endometriosis syndrome. Circulating endometrial cells (CECs) have been previously detected in patients with pelvic endometriosis. Could CECs bring new insights into pneumothorax management?

METHODS

This study aims to describe the occurrence and molecular characteristics of CECs in women with spontaneous pneumothorax (SP) (N = 20) with high suspicion of its catamenial character. CECs were enriched from peripheral blood by size-based separation (MetaCell). In addition to cytomorphology, gene expression profiling of captured cells was performed for 24 endometriosis-associated genes.

RESULTS

CECs were present in all 20 patients with SP. Enriched CECs exhibited four character features: epithelial, stem cell-like, stroma-like, and glandular. However, not all of them were present in every sampling. Gene expression profiling revealed two distinct phenotypes of CECs in SP and/or CP: one of them refers to the diaphragm openings syndrome and the other to endometrial tissue pleural implantations. Comparisons of the gene expression profiles of CECs in pneumothorax (CECs-SP group) with CECs in pelvic endometriosis (CECs-non-SP group) have revealed significantly higher expression of HER2 in the CECs-SP group compared with the CECs-non-SP group.

CONCLUSIONS

This proof-of-concept study demonstrates successful isolation and characterization of CECs in patients with SP. Identification of CECs in SP could alert endometriosis involvement and help early referral to gynecologic consultation for further examination and treatment.

Large Spontaneous Right Catamenial Pneumothorax with Diaphragmatic Defect and Liver Herniation

Catamenial pneumothorax is a spontaneous pneumothorax that occurs predominantly women of child bearing age. We describe a case of a 40-year-old nulliparous woman with medical history significant for endometriosis who presented with severe chest tightness of one-day duration. Chest radiography (CXR) showed a large right spontaneous pneumothorax, what was thought to be a 5.6 cm pleural mass at the right lung base. Following pneumothorax diagnosis, the patient underwent emergent right thoracostomy with pigtail catheter placement. A repeat CXR revealed marked re-expansion of the lung but persistence of a right pleural mass. Follow up computed tomography scan of the chest showed a 33 mm diaphragmatic defect with 5.8 x 4.6 x 3.9 cm area of herniated liver corresponding to the presumed pleural mass. Following complete thoracic imaging, patient underwent video-assisted thoracoscopic surgery, mechanical pleurodesis, and open repair of the right diaphragmatic defect. Intraoperatively, an endometrial implant was noted on the chest wall. On postoperative day three, she began her menstrual cycle and was evaluated by gynecologist who recommended hormonal therapy to reduce risk of recurrent pneumothorax. Due to a persistent air leak, the chest tube was transitioned to a Heimlich valve to facilitate home discharge. The patient was discharged on postoperative day eight, seen as outpatient with resolution of air leak and removal of chest tube.

Catamenial Pneumothorax: A Rare Cause of Chest Pain in the Emergency Department

Catamenial pneumothorax (CP) is defined as recurrent spontaneous pneumothorax occurring within 72 hours before or after onset of menstruation. The aetiology of this syndrome is unknown, although many theories have been proposed to explain it. A 43-year-old female presented to our emergency room with a complaint of left sided chest pain. She had no dyspnoea or haemoptysis during the admission. She had a history of pelvic endometriosis without any complaints for three years. Pneumothorax or pneumonia was not detected on chest X-ray. Blood tests and electrocardiogram findings did not support any cardiac or infectious cause. Computed tomography showed a pneumothorax on the mediastinal side of left hemithorax. The patient was referred to a thoracic surgeon. A thoracoscopy for histological confirmation was performed and the diagnosis of CP was made with a histological intervention.

Catamenial pneumothorax - a review of the literature

Catamenial pneumothorax should be defined as recurrent accumulation of air in the pleural cavity in reproductive-age women without concomitant respiratory diseases. The sine qua non criterion is the occurrence of the pneumothorax in the period of 72 hours before or after the menses. Additional criteria include characteristic pleural lesions, right-sided occurrence, and coexistence of endometriosis. There are no radiological or pathological conditions allowing an exact confirmation of catamenial pneumothorax. In the case of catamenial pneumothorax, treatment failure most commonly consists in disease recurrence. It may occur even as late as several years after the initial treatment. The recurrence rate in patients undergoing surgery ranges from 8% to 40%. Finding and resecting the visible pleural lesions is of key importance during surgical treatment. Reconstruction of the diaphragm must be performed in every patient in whom diaphragmatic perforations are found. Hormonal therapy seems to be effective in sustaining the effects of surgical treatment.

Catamenial pneumothorax

Catamenial pneumothorax (CP) is the most common form of thoracic endometriosis syndrome, which also includes catamenial hemothorax, catamenial hemoptysis, catamenial hemopneumothorax and endometriosis lung nodules, as well as some exceptional presentations. Usually onset of lung collapse is less than 72 hours after menstruation. Most commonly occurs in women aged 30-40 years, but has been diagnosed in young girls as early as 10 years of age and post menopausal women (exclusively in women of menstrual age) most with a history of pelvic endometriosis. Diagnosis can be hinted by high recurrence rates of lung collapse in a woman of reproductive age with endometriosis. Moreover; CA-125 is elevated. Video-assisted thoracoscopy or medical thoracoscopy is used for confirmation. In our current work we will present all aspects of CP from diagnosis to treatment.

Menstrual suppression: current perspectives

Menstrual suppression to provide relief of menstrual-related symptoms or to manage medical conditions associated with menstrual morbidity or menstrual exacerbation has been used clinically since the development of steroid hormonal therapies. Options range from the extended or continuous use of combined hormonal oral contraceptives, to the use of combined hormonal patches and rings, progestins given in a variety of formulations from intramuscular injection to oral therapies to intrauterine devices, and other agents such as gonadotropin-releasing hormone (GnRH) antagonists. The agents used for menstrual suppression have variable rates of success in inducing amenorrhea, but typically have increasing rates of amenorrhea over time. Therapy may be limited by side effects, most commonly irregular, unscheduled bleeding. These therapies can benefit women’s quality of life, and by stabilizing the hormonal milieu, potentially improve the course of underlying medical conditions such as diabetes or a seizure disorder. This review addresses situations in which menstrual suppression may be of benefit, and lists options which have been successful in inducing medical amenorrhea.

Anesthetic evaluation and management of a patient with thoracic endometriosis syndrome presenting for elective surgery

Thoracic endometriosis syndrome is a relatively uncommon disorder characterized by recurrent pneumothoraces, hemothorax, chest pain, dyspnea, and hemoptysis within 48 to 72 hours of menstruation. A 34 year old, ASA physical status 2 woman with recurrent catamenial pneumothoraces due to thoracic endometriosis syndrome is presented. After treatment with video-assisted thoracoscopic surgery, she underwent successful elective diagnostic abdominal laparoscopy without incident. The presence of parenchymal injury and damage predisposes these patients to ventilator-induced lung injury. Postponement of surgery until the intermenstrual period, with lung protective ventilation, allows patients with this disease to successfully undergo general anesthesia and surgery.

Catamenial pneumothorax: a rare entity? Report of 5 cases and review of the literature

OBJECTIVE

Spontaneous recurrent pneumothorax during menstruation is reported as catamenial pneumothorax. It is encountered in 3-6% of spontaneous pneumothorax cases among menstruating women. The percentage among women referred for surgery is significantly higher (25-30%). Although it usually involves the right-side (85-95%) it can be left-sided or bilateral. It is associated with diaphragmatic perforations and/or thoracic endometriosis. There is pelvic endometriosis in up to 30-51% of cases. The lesions that are not always found may present as small or larger holes at the central tendon of the diaphragm, as red, blueberry, brown spots or larger nodules at the diaphragm, the visceral or parietal pleura. Lesion histology may reveal endometriosis. We present 5 cases of catamenial pneumothorax treated surgically during the last 6 years.

PATIENTS AND METHODS

Five women, with a mean age of 34+/-9.9 years (median 38, range, 19-45 years) presented with right-sided recurrent catamenial pneumothorax. In 3 patients diaphragmatic perforation(s) were found; perforation suturing (n=1), and diaphragmatic plication reinforced with bovine pericardial patch (n=1) were performed. All patients underwent atypical resection of upper and/or middle lobe segments of lung parenchyma that appeared abnormal (haemorrhagic/emphysematous or blebs). Four patients underwent pleurodesis and 1 patient underwent pleurectomy. Four interventions were performed through video assisted thoracoscopic surgery, while diaphragmatic plication was performed through a video assisted mini-thoracotomy. Histology did not reveal endometriosis tissue.

RESULTS

The postoperative course was uneventful. The patients were extubated in theatre and were discharged home at a mean of 7+/-4 days (median 6 days, range, 4-14 days). Two of them received hormonal therapy [Gonadotropin Releasing Hormone (GnRH) analogue] postoperatively. At a follow-up of 14.16 patient-years (mean 2.83+/-1.08 years, range, 1.33-3.83 years) there was recurrence, 6.5 months postoperatively, in one patient that had not undergone closure of a tiny diaphragmatic hole and had not received hormonal treatment postoperatively. She was treated medically (amenorrhea for 6 months with GnRH analogue) and had no further recurrences (in 3.3 years).

CONCLUSIONS

Surgery is the treatment of choice of catamenial pneumothorax. It should aim to complete management of all lesions. The most common complication is recurrence. Early diagnosis and multidisciplinary treatment including hormonal therapy may be beneficial in high risk patients.

Bilateral thoracic endometriosis affecting the lung and diaphragm

INTRODUCTION

Endometriosis of the lung and the diaphragm is rare. Patients may present with symptoms such as shortness of breath, chest pain, and shoulder pain or they may be asymptomatic. Of note, there have been few reports of bilateral catamenial disease, and no reports, to our knowledge, of bilateral pathology proven pulmonary parenchymal endometriosis.

CASE

A 43-year-old with stage IV endometriosis and large leiomyoma underwent a laparoscopic hysterectomy and treatment of endometrial lesions in 2005. In March and April of 2011, she presented with bilateral pneumothoraces. She subsequently underwent video-assisted thoracoscopy as well as resection and fulguration of bilateral lung and diaphragmatic endometriosis. Pathology confirmed endometrial implants in the lung parenchyma bilaterally.

CONCLUSION

Catamenial pneumothorax is the most common presentation of thoracic endometriosis. However, bilateral catamenial pneumothoraces are rare. To the best of our knowledge, this case reflects the first report of pathology proven bilateral lung and diaphragm endometriosis.

Thoracic endometriosis: revisiting the association between clinical presentation and thoracic pathology based on thoracoscopic findings in 110 patients

Thoracic endometriosis (TE) is a rare disorder affecting women during their reproductive years. The etiopathogenesis of this disease is not well understood; the prevailing opinion is based on analysis obtained from case reports and small case series. A 1996 review of TE was not able to address the association between clinical presentation and thoracic pathology due to a paucity of thoracoscopic findings in these earlier cases. Since the year 2001, most published cases and series have included thoracoscopic findings. Therefore, we compiled data from case reports and case series published in English from January 2001 to July 2007 to analyze the demographics, clinical characteristics, and thoracoscopic findings, and to study the relationship between thoracoscopic findings and clinical presentation in patients with thoracic endometriosis. The clinical presentations in 110 patients were as follows: pneumothorax in 79 (72%), hemoptysis in 16 (14%), hemothorax in 13 (12%), and lung mass in 2 (2%). Ninety-one of the 110 (85%) patients underwent thoracotomy or thoracoscopy. The right hemithorax was more often affected (85%) than the left side (p = 0.008). The mean (standard deviation [SD]) age of all patients was 34 (7.6 yr). The mean age of patients presenting with hemoptysis (25.9 +/- 4.6 yr) was significantly lower than the age of those presenting with pneumothorax and hemothorax (p < 0.01). There was no significant association between the presence of diaphragmatic defects and pneumothorax (odds ratio [OR], 0.3; 95% confidence interval [CI], 0.05-1.58; p = 0.23). The presence of parietal and visceral pleural implants was associated with a fivefold increase in hemothorax (OR, 5.55; 95% CI, 1.20-25.53; p < 0.01).Hemoptysis occurring in younger subjects may be the earliest manifestation of parenchymal lung involvement in TE. Diaphragmatic defects do not increase the risk for pneumothorax. Hemothorax reflects an increased burden of pleural implants in TE.

Seasonal variation in the incidence of spontaneous pneumothorax and its association with climate: a nationwide population-based study

This study investigated seasonal variation in the incidence of spontaneous pneumothorax (SP) among young adults aged 15-44 years, in order to identify possible associations with meteorological parameters in a subtropical Asian climate. Neither particular months nor seasons of the year were significantly associated with the incidence of SP.

BACKGROUND AND OBJECTIVE

While links between meteorological conditions and the incidence of spontaneous pneumothorax (SP) have been postulated, the findings are controversial. In this first large-scale, nationwide, population-based study, seasonal variation in the incidence of SP among young adults aged 15-44 years was investigated, in order to identify possible associations with meteorological parameters (rainfall, ambient temperature, relative humidity, atmospheric pressure, hours of sunshine) in a subtropical Asian climate.

METHODS

Data (2001-2005) from the National Health Insurance Research Database were used to identify a total of 8575 patients who had been hospitalized with a principal diagnosis of SP. The autoregressive integrated moving average method was used to evaluate the effects of seasonality and monthly climatic factors on the incidence of SP.

RESULTS

The incidence of SP was not significantly associated with either particular months of the year or seasons. After adjusting for seasonality, month and time trends, relative humidity was positively associated with the monthly incidence of SP among men, while ambient temperature and rainfall were significantly associated with SP events among women. However, changes in monthly atmospheric pressure did not appear to influence the monthly risk of SP.

CONCLUSIONS

These results do not support the premise that seasonal factors are involved in precipitating SP, although certain climatic parameters showed weak associations with the incidence of SP. Future studies should investigate other combinations of weather phenomena and potential triggering factors, in order to shed light on the occurrence of SP in various regions and climatic conditions, and among both men and women.

A case of catamenial pneumothorax with diaphragmatic fenestrations

BACKGROUND

Considerable controversy exists with regards to the physiopathogenesis of catamenial pneumothorax. The rarity of catamenial pneumothorax makes understanding of its pathophysiology and verification of etiological mechanisms difficult.

OBJECTIVE

To contribute evidence to the knowledge base on the pathogenesis of catamenial pneumothorax.

CASE REPORT

We describe a case of catamenial pneumothorax with images that substantiate the pore hypothesis as a cause of recurrence of air in the pleural cavity in this patient.

CONCLUSION

Our case report contributes evidence that transperitoneal migration of endometrial implants may occur through diaphragmatic fenestrations. Surgical options may be more viable to prevent recurrent pneumothoraces in such patients.

[Imaging findings in catamenial pneumothorax]

OBJECTIVE

To show the presentation and imaging findings of catamenial pneumothorax.

MATERIAL AND METHODS

We reviewed the imaging tests (plain-film radiography, computed tomography [CT], magnetic resonance [MR]) performed in six women aged between 28 and 44 years with recurrent pneumothorax associated to menstruation. All patients underwent videothoracoscopic surgery and thoracotomy was necessary in three due to the recurrence of the pneumothorax.

RESULTS

CT was performed in three cases and found pleural nodules in two; one of these was confirmed at MR. Pleural endometriosis was only demonstrated at histological examination in one case. Diaphragmatic blebs and bullae were found in five of the six patients.

DISCUSSION

The most common symptoms of catamenial pneumothorax are chest pain, dyspnea, and hemoptysis. The right side is affected in 90% of cases. The radiological findings are pneumothorax, hemothorax, or hydropneumothorax. CT and MR can help to identify the pleural lesions that are not visible on plain-film radiographs and are a very common finding at surgery.

CONCLUSION

The diagnosis of catamenial pneumothorax should be suspected in fertile-aged women with a history of recurrent pneumothorax coinciding with menstruation. CT and MR can help to identify lesions suspicious of endometriosis.

Catamenial pneumothorax: a case report and review of the literature

A 39-year-old woman presented with the chief complaint of right-sided chest pressure and shortness of breath with dry cough for 3 days. These symptoms coincided with the onset of her menstrual cycle. Her physical examination was significant for decreased breath sounds at the right lung base. Her chest x-ray showed a moderate sized right pneumothorax extending from the apex to the lung base and a small amount of pleural fluid, findings that were verified by chest CT. The patient was seen by consultants from the pulmonary, obstetrics/gynecology, and thoracic surgery services, who agreed that the clinical diagnosis was catamenial pneumothorax, probably associated with thoracic endometriosis. The patient was discharged on levonorgestrel/ethinyl estradiol tablets, which she opted not to take. Three months later, she had similar symptoms that occurred again at the time of menstruation. Her chest x-ray now showed a 10% right-sided pneumothorax. Catamenial pneumothorax is a rare condition affecting women in their reproductive years. Women with this condition most commonly have right-sided pneumothorax. The proper diagnosis is based on being aware of the existence of this relatively rare condition and relating the symptoms of pneumothorax temporally to the menses.

Spontaneous hemopneumothorax in children: case report and review of literature

Spontaneous hemopneumothorax is rare, occurs in young adolescents, and can be life threatening secondary to massive bleeding. An adolescent with spontaneous hemopneumothorax and shock managed by tube thorascostomy is described here. We compared our case with published data of spontaneous hemopneumothorax in the pediatric age group. Spontaneous hemopneumothorax involves the accumulation of air and blood in the pleural space in the absence of trauma or other obvious causes. Spontaneous hemopneumothorax is usually seen in adolescents, more common in males than females. The common clinical features of spontaneous hemopneumothorax include dyspnoea and chest pain, and 30% present with hypovolemic shock. The bleeding can result from a torn adhesion between the parietal and visceral pleurae, from a rupture of vascularized bullae, or from torn congenital aberrant vessels. Over the last 6 decades, the treatment has progressed from the thoracotomy to minimally invasive techniques such as video assisted thoracoscopic surgery, with great reduction in mortality and recurrence rates. Although a rare entity, diagnosis of spontaneous hemopneumothorax must be considered in young adolescents presenting with spontaneous onset of chest pain and dyspnoea with radiograph findings of hydropneumothorax and/or signs of shock.

Pleural disease in lymphangioleiomyomatosis

Pleural disease is a common complication of lymphangioleiomyomatosis (LAM). The incidence and recurrence rates of secondary spontaneous pneumothorax in LAM are the highest among chronic pulmonary disorders. Most patients have at least one pneumothorax before LAM is diagnosed, and pneumothorax is often the sentinel event that leads to the diagnosis. Although early, definitive treatment for recurrent pneumothorax by pleurodesis is recommended, the failure rate for chemical and surgical approaches is high. Chylothorax occurs owing to obstruction of lymphatics by proliferating smooth muscle cells and often requires pleurodesis to control expanding and recurrent effusions. Because of the rarity of the LAM, few data exist on whether the occurrence of pleural complications in LAM accelerates functional decline or portends a worse prognosis.

Pathology of the Pleura

The pleura and lung are intimately associated and share many pathologic conditions. Nevertheless, they represent two separate organs of different embryonic derivation and with different yet often symbiotic functions. In this article, the authors explore the pathologic manifestations of the many conditions that primarily or secondarily affect the pleura.
