Abstract
|
|---|
Catamenial hemoptysis is a rare condition, and only 36 cases have
been reported since the first published case. We describe a woman with
catamenial hemoptysis recurring over 8 years. The lesion was diagnosed
using chest CT scan during menses and was also visualized clearly via
thoracoscopy. The patient was treated successfully with a partial
resection of the lung using video-assisted thoracic surgery (VATS) and
has been asymptomatic for 14 months since the operation. We suggest
that VATS for catamenial hemoptysis is a more effective treatment than
medical therapy.

In this study, we describe a
patient with catamenial hemoptysis. The lesion was diagnosed in the S3
segment of the right lung using a CT scan of the chest during menses.
The patient underwent thoracoscopic partial resection of the right lung
and has been asymptomatic for 14 months after surgery.

Case Report
|
|---|
A 28-year-old woman presented with recurrent hemoptysis
with the onset of menses. At the age of 17 years, she underwent an
induced abortion in 1989. In 1991 (at the age of 19 years), she
experienced her first episode of catamenial hemoptysis. Just after the
onset of menses, hemoptysis occurred, lasted for a few days, and
resolved spontaneously. For 6 years, she had recurrent hemoptysis
during menses. Although hemoptysis disappeared during her first
birth in 1997, this symptom appeared again after delivery. Since the
start of symptoms, she has refused medication such as hormone therapy
because of her wish to become pregnant again. Therefore, she was
admitted to our hospital for surgical treatment in July 1999. She had
no symptoms other than hemoptysis. The result of the physical
examination, which included a gynecologic examination, was normal.
After hospital admission, a chest radiograph showed no abnormal
findings with the onset of hemoptysis during menses. During menses,
fiberoptic bronchoscopy revealed no endobronchial lesions, and bleeding
from the right upper lobe bronchus was detected. During menses, a CT
scan of the lung revealed an ill-defined opacity in the right S3
segment (Fig 1
). Since the clinical diagnosis was pulmonary endometriosis, judging
from her history, we performed an operation using video-assisted
thoracic surgery (VATS) on August 4, 1999. The ports inserted for VATS
were 5 mm in diameter at the fourth intercostal space and 12 mm in
diameter at the fifth and seventh intercostal spaces. During
observation of the right thoracic cavity via thoracoscopy during VATS,
we confirmed the bleeding lesion as pigments composed of several light
brown spots in S3 (Fig 2
). We performed a partial resection of the right upper lobe (S3), so as
to remove all of the pigmented lesions, using autosuture instruments
(EndoGIA; Autosuture; Tokyo, Japan) under VATS. The postoperative
course was uneventful. The patient has been asymptomatic for 14 months
after surgery. The macroscopic specimen showed pigments composed of
several light brown spots in the resected lung (Fig 3
). Microscopically, bleeding and edema were found in lung parenchyma,
and the existence of macrophage, including hemosiderin, suggested
repeated alveolar hemorrhage (Fig 4
).

Discussion
|
|---|
Catamenial hemoptysis is an uncommon disease. Since Lattes et
al1
described a case of hemoptysis associated with menses
by pulmonary endometriosis in 1956, only 36 cases have been reported in
the English-language literature.2

Although all these
cases were assigned to pulmonary endometriosis, histopathologic
confirmation of the diagnosis has been obtained in only one third of
the cases.33
Histopathologic confirmation of pulmonary
endometriosis is possible when the resection of the lung is performed
just before the onset of menses. In this patient, since the operation
was performed during menses, pathologic findings of the resected lung
did not show any ectopic endometrial tissue; however, infiltration of
macrophages including hemosiderin was observed as a result of repeated
bleeding in the parenchyma of the lung.
The pathogenesis of pulmonary endometriosis is not well understood.
Park34
postulated that pulmonary endometriosis was
assigned to the filter function of the pulmonary vascular network with
trapping of endometrial particles from the pelvic organ,
which is a process similar to pulmonary embolism. The hematogenous
dissemination of the endometrium was thought to be caused by
uterine procedures involving curettage or cesarean section.
In the present case, the patients history of an induced abortion can
support the microembolization theory.
A diagnosis of catamenial hemoptysis is usually delayed because of
failure to associate the patients symptoms with menses. It is most
important to take a complete patient history to make an accurate
diagnosis.
Location of the pulmonary endometriosis is difficult to confirm.
Although chest radiography is useful and may reveal solitary or
multiple pulmonary nodules with cyclical changes in size,
it usually shows normal findings.9
16
In this case,
the finding of the chest radiograph obtained during menses was
normal.
Chest CT scans are more useful than radiographs for locating pulmonary
endometriosis. Lesions that are not found using chest radiography can
be clearly detected.9
A CT scan of pulmonary endometriosis
may demonstrate ill-defined or well-defined opacities, nodular lesions,
thin-walled cavities, or bullous
formations.17
23
In this patient, the CT scan taken during
menses showed consolidation surrounding an ill-defined nodule in the
right upper lobe (S3), and we confirmed the location of pulmonary
endometriosis.
Although diagnostic bronchoscopy should be performed during menses, it
is very difficult to detect the bleeding lesion using
bronchoscopy.17
This is because in most cases, pulmonary
endometriosis is more commonly detected in the distal pulmonary
parenchyma than in the mucosa of the large bronchi.24
In
such patients, we found that bleeding by pulmonary endometriosis was
detected in the right upper bronchus, but definite histologic evidence
of endometriosis could not be obtained.
Treatment of pulmonary endometriosis may be medical or surgical. To
date, medical treatment involving danazol and gonadotropin-releasing
hormone (GnRH) analogs has been recommended as the first choice in
pulmonary endometriosis.7
20
Danazol is a synthetic
steroid with antiestrogenic and weakly androgenic effect. However, side
effects of danazol therapy are often observed, involving weight gain,
climacteric symptoms, and virilization. Since GnRH analogs inhibit the
release of GnRH from the pituitary gland, the level of sex hormones
decreases. Medical treatment is expensive, and the symptoms often recur
after it is discontinued.21
Furthermore, since these drugs
may cause sterility, patients who wish to conceive sometimes refuse to
undergo these hormone therapies.
In the past, several cases of resection of lung by thoracotomy were
performed.1
32
Surgical treatment by thoracotomy was so
invasive that it could not be recommended as a first
choice.7
However, technologic advances in surgical
procedures have made this a less invasive and safer method.
Because VATS was developed in association with an improvement in video
camera technology and development of percutaneous endoscopic staplers,
this method may be a safer treatment and advantageous for some
procedures in reducing postoperative analgesic requirements and
shortening hospital stay. Furthermore, the bleeding lesion in the lung
can be visualized clearly with video-assisted thoracoscopy. VATS can
certainly be a successful therapy for pulmonary endometriosis,
especially when patients wish to become pregnant, because of the lower
degree of recurrence when compared to drug therapy. We believe that
partial resection of the lung through thoracoscopy can be effective in
the treatment of pulmonary endometriosis, because, in this case,
hemoptysis had disappeared 14 months following surgery. Resection of
the lung should be performed so as to remove all of the pigmented
lesions.
However, pleural manifestations are often difficult to treat surgically
because the lesions tend to be multifocal.35
Therefore, a
single focus of bleeding must be definitively located by using CT scan
before surgery. When lesions are multiple or when their location cannot
be detected, hormone therapy or oophorectomy should be considered as an
alternative treatment. We suggest that VATS for catamenial hemoptysis
is a minimally invasive technique and is a safe and effective method,
and that the diagnosis and location of pulmonary endometriosis should
be confirmed using chest radiography and CT scanning before surgical
treatment.
