Currently, there have been no reports of massive haemoptysis or death. Cyclic haemoptysis is a sign of pulmonary parenchymal endometriosis; ectopic endometrial tissue in the lung responds to cyclical hormonal variation, bleeding along with the normal endometrium located in the uterus. [2]
Thoracic endometriosis is the most common non-abdominal site of involvement and is also the primary risk factor for catamenial pneumothorax. [5] Catamenial pneumothorax is the primary clinical presentation of thoracic endometriosis, and is defined as recurrent episodes of lung collapse within 72 hours before or after menstruation.
Sciatic endometriosis also called catamenial or cyclical sciatica, is a rare form where endometriosis affects the sciatic nerve. Diagnosis is usually confirmed through MRI or CT-myelography. [48] Endometriosis can also impact a woman's fetus or neonate, increasing the risks for congenital malformations, preterm delivery and higher neonatal ...
Infant prematurity is the factor most commonly associated with pulmonary hemorrhage. Other associated factors are those that predisposed to perinatal asphyxia or bleeding disorders, including toxemia of pregnancy, maternal cocaine use, erythroblastosis fetalis, breech delivery, hypothermia, infection (like pulmonary tuberculosis), Infant respiratory distress syndrome (IRDS), administration of ...
Pulmonary hematopoiesis also appears to play an important role in adults. [5] In comparison to the bone marrow, where trilineage hematopoiesis occurs, the lungs preferentially contribute to the production of platelets through a resident population of megakaryocytes. This is supported by studies showing that blood leaving the lungs has more ...
PCOS is caused by an imbalance of reproductive hormones. Symptoms can include irregular menstrual periods, and it is one of the most common causes of infertility in women. Endometriosis is a ...
Hematometra typically presents as cyclic, cramping pain in the midline of the pelvis or lower abdomen. [1] Patients may also report urinary frequency and urinary retention . [ 2 ] Premenopausal women with hematometra often experience abnormal vaginal bleeding, including dysmenorrhea (pain during menstruation ) or amenorrhea (lack of ...
A pulmonary contusion is another cause of bleeding within the lung tissue, but these result from microhemorrhages, multiple small bleeds, and the bleeding is not a discrete mass but rather occurs within the lung tissue. An indication of more severe damage to the lung than pulmonary contusion, a hematoma also takes longer to clear. [3]
