Endometriosis pleuropulmonar y neumotórax catamenial asociado: reporte de caso / Pleuropulmonary endometriosis and associated catamenial pneumothorax:A case report

Resumen ANTECEDENTES: El tórax es la localización extrapélvica más frecuente de la endometriosis; esto sin que su incidencia se haya determinado con estudios suficientes. Tampoco se ha establecido del todo su fisiopatología, pero aun así se han planteado diversas teorías. El neumotórax catamenial es una de las posibles manifestaciones que hacen complejo establecer el diagnóstico e indicar un tratamiento. CASO CLÍNICO: Paciente de 31 años, con antecedente de neumotórax espontáneo a repetición, que acudió a consulta debido a disnea y dolor torácico de un mes de evolución. La radiografía de tórax evidenció el neumotórax del 50% en la parte derecha y la necesidad de la toracostomía. Puesto que los episodios de neumotórax ocurrían en fase catamenial, pero sin poder establecer una causa clara del cuadro clínico, se procedió a la toracoscopia diagnóstica con toma de muestra para estudio histopatológico. Durante el procedimiento se detectaron múltiples lesiones pseudonodulares, de aspecto inflamatorio crónico a nivel pleural y del parénquima pulmonar. El reporte histopatológico fue compatible con endometriosis pleuropulmonar; se le indicó terapia hormonal. Ante la evolución clínica satisfactoria y posoperatorio sin complicaciones la paciente fue dada de alta del hospital. CONCLUSIÓN: El neumotórax catamenial, como consecuencia de una endometriosis pleuropulmonar, es un diagnóstico realmente excepcional y su sospecha debe vincularse con el ciclo menstrual. La atención médica de las pacientes con este diagnóstico debe ser interdisciplinaria, no solo por las estrategias diagnósticas sino por la complejidad del tratamiento y su seguimiento. El tratamiento de elección suele requerir intervenciones quirúrgicas, sumadas a la indicación de la medicación hormonal para prevenir recurrencias, con tasas de éxito favorables. Están pendientes los estudios que establezcan la respuesta del tejido endometrial ectópico torácico al tratamiento médico.

Abstract BACKGROUND: The thorax is the most frequent extrapelvic location of endometriosis, although its incidence has not been sufficiently studied. Its pathophysiology has not been fully established, but several theories have been put forward. Catamenial pneumothorax is one of the possible manifestations that make it difficult to establish the diagnosis and indicate treatment. CLINICAL CASE: A 31-year-old female patient, with a history of repeated spontaneous pneumothorax, presented for consultation due to dyspnea and chest pain of one month of evolution. Chest X-ray showed a 50% pneumothorax on the right side and the need for thoracostomy. Since the episodes of pneumothorax occurred in catamenial phase, but without being able to establish a clear cause of the clinical picture, diagnostic thoracoscopy with sampling for histopathological study was performed. During the procedure multiple pseudonodular lesions of chronic inflammatory aspect were detected at pleural and lung parenchyma level. The histopathological report was compatible with pleuropulmonary endometriosis; hormonal therapy was indicated. Given the satisfactory clinical evolution and postoperative course without complications, the patient was discharged from the hospital. CONCLUSION: Catamenial pneumothorax, as a consequence of pleuropulmonary endometriosis, is a truly exceptional diagnosis and its suspicion should be linked to the menstrual cycle. The medical care of patients with this diagnosis should be interdisciplinary, not only because of the diagnostic strategies but also because of the complexity of the treatment and its follow-up. The treatment of choice usually requires surgical interventions, added to the indication of hormonal medication to prevent recurrences, with favorable success rates. Studies establishing the response of thoracic ectopic endometrial tissue to medical treatment are pending.

Neumotórax catamenial / Catamenial pneumothorax

Resumen El síndrome de endometriosis torácica (TES) es un trastorno poco común caracterizado por la presencia de tejido endometrial ectópico en la cavidad torácica. La manifestación clínica típica es un neumotórax espontáneo, que generalmente se presenta con dolor torácico, disnea y/o tos. El diagnóstico requiere un alto nivel de sospecha clínica junto con una historia ginecológica completa. Los estudios de imáge nes pueden ayudar con el diagnóstico, pero el gold standard es la cirugía toracoscópica videoasistida (VATS). Se ha demostrado que el tratamiento quirúrgico en combinación con al menos 6 meses de tratamiento médico hormonal mejora el pronóstico y reduce la recurrencia de esta entidad. Presentamos el caso de una paciente de 40 años con antecedentes de endometriosis pélvica y múltiples episodios de neumotórax, que consultó en nuestra institución por un nuevo episodio de neumotórax espontáneo. Se realizó una VATS donde se identificaron nódulos en la pleura parietal y orificios diafragmáticos. En el postoperatorio continuó con tratamiento hormonal. A los 6 meses de seguimiento refirió mejoría del dolor y no presentó nuevos episodios de neumotórax.

Abstract. Thoracic endometriosis syndrome (TES) is a rare disorder characterized by the presence of ectopic endometrial tissue in the chest cavity. The typical clinical manifestation is a spontaneous pneumothorax, which usually presents with chest pain, dyspnea, and/or cough. The diagnosis requires a high level of clinical suspicion and a complete gynecological history. Imaging studies can help with the diagnosis, although the gold standard is video-assisted thoracoscopic surgery (VATS). Surgical treatment in combination with at least 6 months of hormonal medical treatment has been shown to improve the prognosis and reduce the recurrence of this entity. We present the case of a 40-year-old patient with a history of pelvic endometriosis and multiple episodes of pneumothorax, who consulted at our institution for a new episode of spon taneous pneumothorax. A VATS was performed where nodules in the parietal pleura and diaphragmatic orifices were identified. In the postoperative period, she continued with hormonal treatment. At 6 months of follow-up, she reported improvement in pain and did not present new episodes of pneumothorax.

Neumotórax catamenial recurrente. Reporte de caso / Recurrent catamenial pneumothorax. Case report

Resumen El neumotórax catamenial es una condición clínica rara y compleja que debe ser considerada como causa de neumotórax espontáneo y recurrente que a menudo es diagnosticado en forma errónea. Es una patología pulmonar comúnmente asociada a la menstruación, ya que ocurre dentro de las 72 horas antes o después del inicio del sangrado menstrual. La etiología y el mecanismo subyacente exacto no han sido identificados, pero podría ser una forma rara de endometriosis extrapélvica caracterizada por la presencia de tejido endometrial funcional en pleura, parénquima pulmonar y vías respiratorias. El diagnóstico es un desafío, por lo que puede resultar en recurrencias. Debe sospecharse en mujeres jóvenes en edad fértil. La primera línea de tratamiento es médica, mientras que el tratamiento quirúrgico es necesario para evitar la recurrencia. Se presenta un caso de neumotórax catamenial recurrente.

Abstract Catamenial pneumothorax is a rare and complex clinical condition that should be considered as a cause of spontaneous and recurrent pneumothorax that is often misdiagnosed. It is a pulmonary pathology commonly associated with menstruation since it occurs within 72 hours before or after the onset of menstrual bleeding. The etiology and the exact underlying mechanism have not been identified, but it could be a rare form of extra-pelvic endometriosis characterized by the presence of functional endometrial tissue in the pleura, pulmonary parenchyma, and respiratory tract. Diagnosis is a challenge, so it can result in recurrences. It should be suspected in young women of childbearing age. The first line of treatment is medical, while surgical treatment is necessary to avoid recurrence. A case of recurrent catamenial pneumothorax is presented.

Breathlessly bleeding: A case report of Catamenial Pneumothorax / Philippine Journal of Obstetrics and Gynecology

@#Catemenial pneumothorax is the monthly manifestation of air in the lungs that relates to menstruation. Main objective is to impart knowledge on the mechanism and management of catamenial pneumothorax in a patient with recurrent penumothorax. We describe a case of catamenial pneumothorax with description, images and histopathologic evidence of the diagnosis. Standard treatment plan should be made for cases of catamenial pneumothorax.

Neumotórax catamenial / Catamenial pneumothorax

El neumotórax catamenial es de rara presentación. Su curso clínico es variable, y generalmente recurre. Presentamos un caso en una paciente de 35 años con cinco episodios de neumotórax tratados en otra institución. Se diagnosticó y resolvió por videotoracoscopia. Realizamos plicatura diafragmática y pleurodesis. La anatomía patológica confirmó el diagnóstico. Presenta muy buena evolución sin recidivas hasta el día de la fecha. Esta entidad nosológica debe ser considerada en todo neumotórax recidivante de la mujer con periodos menstruales.

Catamenial pneumothorax is of rare presentation. Its clinical course is variable, and it usually recurs. We present a case of a 35 year-old patient with five episodes of pneumothorax previously treated in another institution. Videothoracoscopy was used for diagnosis and treatment, which included a diaphragmatic plication followed by pleurodesis. The anatomopathology confirmed the diagnosis. Postoperative curse was uneventful up to date. Catamenial etiology should be considered in all recurrent pneumothorax occurring in women with menstrual periods.

Thoracic endometriosis with catamenial haemoptysis and pneumothorax: computed tomography findings and long-term follow-up after danazol treatment

Thoracic endometriosis (TE) is an uncommon disorder affecting women of childbearing age. We herein report clinical and thin-section computed tomography (CT) findings of two cases, in which one woman presented with catamenial haemoptysis (CH) alone and another woman presented with bilateral catamenial pneumothoraces (CP) coinciding with CH, a rare manifestation of TE. The dynamic changes demonstrated on thin-section chest CT performed during and after menses led to accurate localisation and presumptive diagnosis of TE in both patients. Following danazol treatment, the patient with CH alone had a complete cure, while the patient with CP and CH had an incomplete cure and required long-term danazol treatment. We discuss the role of imaging studies in TE, with an emphasis on the appropriate timing and scanning technique of chest CT in women presenting with CH, potential mechanisms, treatment and patient outcomes.

Clinical features of thoracic endometriosis: A single center analysis

OBJECTIVE: To analyze the diagnostic profiles and treatment outcomes of patients with thoracic endometriosis at a university hospital. METHODS: A retrospective review of medical records was performed for patients diagnosed with thoracic endometriosis at Gangnam Severance Hospital, Yonsei University College of Medicine, between January 2007 and January 2014. RESULTS: Fifteen patients (median age, 35 years; range, 23-48 years) were evaluated. Patients presented with catamenial hemoptysis (n=8), or catamenial pneumothorax (n=7). Patients with catamenial pneumothorax were significantly older than those presenting with hemoptysis (P=0.0002). Only 3 patients (20%) had coexisting pelvic endometriosis. All patients underwent chest computed tomography; lesions were shown to predominantly affect the right lung (right lung, n=13, 86.7%; left lung, n=2, 13.3%), and were mainly distributed on the right upper lobe (n=9, 60%). Ten patients underwent video-assisted thoracoscopic surgery, and 1 patient underwent a thoracotomy. Intraoperatively, endometriosis-specific findings were observed in 8/11 patients (72.7%); a further 5/11 patients (45.4%) had histologically detectable endometriosis. Over the follow-up period (mean, 18.4 months; range, 2-65 months) 5/15 patients (33%) had clinical signs of recurrence. Recurrence was not detected in any of the 5 catamenial pneumothorax patients that received adjuvant hormonal therapy after surgery. CONCLUSION: The diagnosis and management of thoracic endometriosis requires a multidisciplinary approach, based upon skillful differential diagnosis, and involving careful gynecologic evaluation and assessment of the cyclicity of pulmonary symptoms. Imaging findings are non-specific, though there may be laterality towards the right lung. Since symptom recurrence is more common in those with presenting with pneumothorax, post-operative adjuvant medical therapy is recommended.

Neumotórax catamenial, una etiología infrecuente de neumotórax espontáneo / Catamenial pneumothorax, an uncommon cause of spontaneous pneumothorax

El neumotórax catamenial se define como un neumotórax espontáneo recurrente que tiene relación con la menstruación. Su incidencia es baja, constituyendo el 3-6 por ciento de los casos de neumotórax espontáneo en la mujer en edad fértil. Puede relacionarse con la presencia de endometriosis torácica y fenestraciones diafragmáticas. PRESENTACIÓN DEL CASO: Mujer de 36 años con antecedente de neumotórax derecho hace 9 años. Presentó cuadro de neumotórax espontáneo derecho el cual fue tratado con pleurotomía. Estudio con tomografía computada de tórax mostró bulas apicales en pulmón derecho. Se realizó resección de vértice pulmonar y pleurodesis mecánica por videotoracoscopía. Evolucionó con múltiples recidivas del neumotórax durante los meses siguientes. Las características dela paciente hicieron posible plantear la sospecha de neumotórax catamenial, encontrándose correlación directa entre los episodios de neumotórax y el inicio de la menstruación. Se decidió reintervención quirúrgica por videotoracoscopía. Se observaron lesiones sospechosas de implantes endometriósicos y fenestraciones diafragmáticas. El estudio histopatológico del tejido resecado fue sugerente de tejido endometrial. Se inició además tratamiento hormonal con anovulatorios. Presentó nueva recidiva durante el mes siguiente, la cual fue tratada con pleurotomía. Actualmente se encuentra asintomática a 6 meses de seguimiento. DISCUSIÓN: El neumotórax catamenial es un tipo infrecuente de neumotórax espontáneo secundario. Se plantean múltiples hipótesis para explicar su etiopatogenia. El antecedente de neumotórax espontáneo recidivado en una mujer en edad fértil, obliga a sospecharlo evaluando la relación con los ciclos menstruales...

Catamenial pneumothorax is defined as a recurrent spontaneous pneumothorax related with menstruation. Its incidence is low, being 3-6 percent of cases of spontaneous pneumothorax in women of reproductive age. It has been related with thoracic endometriosis and diaphragmatic fenestrations. Multiple hypotheses are proposed to explain its pathogenesis. Case report: A 36 year old woman with a history of right pneumothorax9 years ago. She presented a right spontaneous pneumothorax which was treated with pleurotomy. Chest computed tomography showed apical bullae in the right lung. Resection of lung apex and mechanical pleurodesis by videothoracoscopywas performed. During the following months, she presented multiple recurrences of pneumothorax. Patient characteristics made possible the suspicion of catamenial pneumothorax. Direct correlation between episodes of pneumothorax and the onset of menstruation was found. Reoperation by videothoracoscopy was decided. During the surgery, lesions suspected of endometriosis implants and diaphragmatic fenestrations were observed. Histopathological study of the resected tissue was suspected of endometrial tissue. Hormonal treatment with oral contraceptive pills was also initiated. The following month, shewas submitted with a new pneumothorax episode which was treated with a chest tube. Currently the patient is asymptomatic 6 months follow up. Discussion: Catamenial pneumothorax is an uncommon cause of secondary spontaneous pneumothorax. Multiple hypotheses are proposed to explain its pathogenesis. A history of recurrent spontaneous pneumothorax in a woman of reproductive age requires the evaluation of the relationship with menstrual cycles...

Neuroactive steroids and their role in epilepsy.

Neuroactive steroids are the certain steroids that alter neuronal excitability via the cell surface through interaction with certain neurotransmitter receptors. Neuroactive steroids regulate physiological functions of the central nervous system and have possible therapeutic potential in neurological diseases. They have been shown to affect neuronal excitability via their interaction with the ligand-gated ion channel family, such as the GABAA receptor by acting genomically as well as nongenomically. Positive modulators of GABAA receptor have anticonvulsant action as they enhance GABAergic transmission thereby increasing the seizure threshold. By virtue of these properties, neurosteroids appear to be relevant to pathophysiology and pharmacological treatment of many neurological diseases including catamenial epilepsy, stress induced epilepsy, temporal lobe epilepsy, alcohol withdrawal seizures, infantile spasm and status epilepticus. So far, only synthetic neurosteroid, ganaxolone has been tried in treatment of epilepsy and has shown good efficacy and tolerability. But, human data of trials are limited and hence, large double-blinded, placebo-controlled, randomized clinical trials are required before their use. The paper reviews the biosynthesis and GABAA receptor modulation of neurosteroids and their potential role in epilepsy.

Catamenial Hemoptysis Treated by Video-assisted Thoracoscopic Surgery / 결핵및호흡기질환

Catamenial hemoptysis is a rare condition that's characterized by recurrent hemoptysis occurring in association with menstruation, and this is associated with the presence of intrapulmonary or endobronchial endometrial tissue. The diagnosis of pulmonary endometriosis can be made according to a typical clinical history and with exclusion of other causes of recurrent hemoptysis. Treatment of pulmonary endometriosis can be medical or surgical; however, the optimal management of this condition is still a matter of debate. Medical therapy may be problematic, due to recurrence of symptoms despite hormonal ablation, and adverse effects from long-term hormone therapy can also be a problem. We report here on a case of pulmonary endometriosis in a 23-year-old woman who presented with hemoptysis that occurred during the first 3 days of menstruation, and this happened over a 4 month period. She was successfully treated by video-assisted thoracoscopic surgery (VATS). No more hemoptysis was noted during 12 months of follow-up.

A case of pulmonary endometriosis presenting with catamenial pneumothorax / 대한산부인과학회지

Endometriosis is a relatively common gynecologic disease. However thoracic endometriosis syndrome is exceedingly rare among various types of external endometriosis. We experienced a case of 35-year-old woman who presented with recurrent episodes of spontaneous right-sided pneumothorax that occurred during her menstrual periods. After the localization of the disease site by means of chest radiography and computed tomography of the thorax, a chest tube was inserted after which bullectomy and pleurodesis using doxycycline were performed. A hormonal treatment with gonadotropin-releasing hormone (GnRH) agonist for 12-months was also conducted. However, right-sided pneumothorax recurred two times after these procedures. Subsequently, surgical excision of diaphragmatic lesion along with pleurodesis was underwent. To prevent recurrence, we maintained long-term GnRH agonist administration with add back therapy using low dose estrogen-progesterone. Menstruation stopped, and the chest pain disappeared. During a 19-months follow-up period, pneumothorax did not recur. We report this case with a brief review of the concerned literatures.

Video-Assisted Thoracic Surgery for Pulmonary Endometriosis: Report of 1 Case / 결핵및호흡기질환

Pulmonary endometriosis is an uncommon disease, and usually detected by catamenial hemoptysis. Treatment of pulmonary endometriosis may be medical(hormone therapy) or surgical. Since hormone therapy may cause sterility, most of patients who wish to conceive usually choose surgical resection. Although video-assisted thoracic surgery(VATS) has advantage of small scar, reducing postoperative pain and shortening hospital stay, it is not easy to locate the precise lesion and resect whole endometrial tissue not to be remained. 17 years old female with catamenial hemoptysis was treated sucessfully with a partial resection of the lung using VATS, and has been asymptomatic for 7months since the operation.

A case of catamenial hemoptysis / 대한산부인과학회지

Endometriosis is relatively common gynecologic diseases, but pulmonary endometriosis is exceedingly rare among various types of external endometriosis. Patients with pleural pulmonary endometriosis present with chest pain, dyspnea, pneumothorax or pleural effusion in relation to menstruation. Patients with parenchymal pulmonary endometriosis present with hemoptysis at the time of menstruation, with or without lung lesions on their chest X-ray. The diagnosis of pulmonary endometriosis is usually made on the basis of the clinical history and the exclusion of other causes of recurrent hemoptysis including tuberculosis, bronchial carcinoid, pulmonary infarction, chronic bronchitis, congenital abnormalities and carcinoma. It can be treated by progesterone, GnRH agonist, Danazol, surgical treatment etc. Hereby we experienced 23 year-old multiparous woman with catamenial hemoptysis. The site of disease/was localized with bronchoscopy and chest CT scanning, and we treated her with Danazol. The literature associated with pulmonary endometriosis is briefly reviewed.

A Case of Pulmonary Endometriosis Resected by Video-Assisted Thoracoscopic Surgery / 결핵

Catamenial hemoptysis is a rare condition caused by thoracic endometriosis that presents as tracheobronchial or pulmonary endometriosis. While hormonal treatment may cause virilization and sterility, due to the antiestrogenic effect, its surgical removal via thoracotomy is a particularly invasive procedure and is not recommended as the first choice treatment in young woman. Successful surgical removal by video-assisted thoracoscopic surgery (VATS) has recently been reported, and may be indicated for young patients who at some stage would like to become pregnant. Herein, a case of a 25-year-old unmarried woman with catamenial hemoptysis, cured by VATS, is reported.

A Case of Catamenial Hemoptysis Treated successfully with Gonadotropin-releasing Hormone (GnRH) Analogue / 결핵

Catamenial hemoptysis is syndrome characterized by bleeding from the bronchial trees and lungs that occurs synchronously with the female menstrual cycle. Etiologic mechanism of pulmonary endometriosis is still controversial, and the diagnosis is usually made on the basis of the clinical history and exclusion of other causes of recurrent hemoptysis. Serial computed tomograms of the chest during and in the interval between menstruations have been proved to be a useful confirmatory test. We experienced a 33-year-old female patient who had been previously diagnosed as pelvic endometriosis pathologically, experienced cyclic hemoptysis during menstruations. The diagnosis of pulmonary endometriosis was made based on her history and changes in the character of the lesions as documented on radiologic studies of the chest. She was treated successfully with GnRH analogue and there is no evidence of recurrence.

Pneumotórax catamenial: uma revisão da literatura a respeito da etiologia, patogênese, terapêutica e relato de um caso / Catamenial pneumothorax: a literature rewiew of etiology, pathogenesis, managmenty and a case report

Introdução: O pneumotórax espontâneo catamenial é uma entidade clínica definida com a presença de ar no espaço pleural, durante as primeiras 48 a 72 horas após o início do fluxo menstrual. Ocorre, preferencialmente, no hemitórax direito, com maior incidência nas terceiras e quartas décadas de vida. Apesar de constituir uma entidade pouco conhecida pela literatura mundial, dada a raridade do quadro, acredita-se que possa estar relacionado à existência de pertuitos diafragmáticos associado ou não à presença de implantes de células endometriais na cavidade torácica. Objetivos: Fazer a revisão da literatura e relatar um caso de pneumotórax catamenial. Material e métodos: Apresentamos um caso de paciente de 28 anos, sexo feminino, admitida no Hospital Monte Sinai com quadro de dispnéia de instalação súbita, tosse persistente e dor no hemitórax direito do tipo pleurítica, irradiada para a região escapular homolateral. Era a quinta vez que apresentava essa sintomatologia. A radiografia do tórax foi realizada com objetivo de se confirmar a presença de pneumotórax. Posteriormente, a paciente foi submetida a videopleuroscopia, com inventário minuncioso do espaço pleural, incluindo a visualização do diafragma e de toda a pleura. Resultados: À videopleuroscopia detectaram-se vários pertuitos diafragmáticos. Enviado material para estudo anatomopatológico, pudemos descartar endometriose pleural. A terapêutica consistiu em pleurectomia, com o objetivo de prevenir novos episódios. Conclusão: Em função da raridade do caso, o pneumotórax catamenial tem seu diagnóstico após vários episódios. Nesse caso específico, o achado de orifícios diafragmáticos permitiu optar pelo tratamento cirúrgico. A paciente encontra-se assintomática.

Introduction: Catamenial pneumothorax is characterized by recurrent accumulation of air in the thoracic space appeared within 48 to 72 hours from the menstrual flow. In most cases, catamenial pneumothorax is right-sided, and most of the affected women are in the third to fourth decades of life. Although it is a rare entity of unknown etiology, there are some possible cause for pnemothorax catamenial have been proposed: 1) rupture of pulmonary bleb; 2) diaphragmatic fenestration; 3) thoracic endometriosis. Objectives: 1) To make a review of the literature about pneumothorax catamenial. 2) To present a case of pneumothorax catamenial caused by diaphragmatic fenestration. Methods: A 28-year-old woman suffered 5 episodes of right-sided pneumothorax, which appeared during menstruation. She had undergone thoracic radiography to confirm the diagnosis. Then she had undergone video-assisted thoracoscopy, with histological examination of diaphragm specimen. Results: We identified diaphragm defects of different extension. Endometriosis could not be found. The patient undergone pleurectomy to prevent further occurrences. Conclusion: Because of its rarity, the diagnosis of catamenial pneumothorax could be difficult. In this present case the patient is assymptomatic before thoracocirurgical intervention, without using anovulatory therapy.

A Case of Parenchymal Pulmonary Endometriosis Diagnosed by Cytology of Bronchoalveolar Lavage Fluid / 대한임상병리학회지

Parenchymal pulmonary endometriosis has unique symptoms such as hemoptysis, dyspnea and chest pain in associated with menstruation. We experienced a case of parenchymal pulmonary endometriosis with the complaints of catamenial hemoptysis. Bronchoalveolar lavage(BAL) was performed when catamenial hemoptysis occurred. The BAL fluid showed many erythrocytes, hemosiderin-laden macrophages, and sheets of endometrial stromal cells.

Computed Tomography of Catamenial Hemoptysis / 결핵

A 41-year-old female was admitted to our hospital for self-audible wheezing sound and dyspnea. On past history, she has been suffered from chest discomfort, and treated recurrently by other hospitals. But, there was no symptomatic improvement. A stridor and mixed wheezing sound was auscultated on whole lung field. PFT revealed fixed type or variable intra- & extra-thoracic air way obstructive pattern. By bronchoscopy & bronchogram, we found web-like structure on the distal trachea. A bronchoplasty was performed and the post-operative PFT showed slight improvement & she had no more complaints.
