Diagnosis With Brief Discussion
- Diagnosis
- Catamenial hemorrhage
- Radiologic Findings
- HRCT scans show regional ill defined nodules with GGO in lateral basal segment of RLL.
Chest PA shows patchy GGO in RMLZ.Two weeks later, Chest PA shows disappearance of previous patchy GGO in RMLZ.
- Brief Review
- Thoracic endometriosis
1> Pleural - catamenial pneumothorax or hemothorax with chest pain and dyspnea
2> Parenchymal - microembolism of endometrial tissue,
3> Clinical problems
- Usually 20-30 yrs old female
- Usually develop within 72 hr of the onset of menstruation
4> CT findings
- Ill-defined opacities (several cm in size)
- Nodules
- Area of consolidation surrounding nodules
- Thin-walled cavities
- Bullae
- Lesions vary in size during the menstrual cycle and disappear after the cessation of menstruation
5> Pathologic feature: Various stage of pulmonary hemorrhage
- Nodule: localized pulmonary hematoma
- Cavitary nodule or bullae: hematoma in which the content had partly or completely emptied
- GGO: parenchymal hemorrhage that was partaly fiiling alveoli
- Consolidation: organizing pneumonia with hemosiderin-laden macrophage or pulmonary hemorrhage completely filling alveoli
- Bandlike opacity: linear fibrosis resultant from chronic hemorrhage
6> Tx. Hormone Tx. (GnRH agonist), surgical resection
