Insights
Chronic expanding hematoma (CEH), a rare pulmonary nodule disease, exhibits slow growth. This case study reveals an inconstant growth rate over 8-11 years, offering insights into CEH
Area of Science:
- Pulmonology
- Pathology
- Radiology
Background:
- Chronic expanding hematoma (CEH) is a rare condition often presenting as a solitary pulmonary nodule.
- The underlying mechanisms of CEH development are not well understood.
- Most reported CEH cases involve Asian patients.
Purpose of the Study:
- To report a case of CEH in a 76-year-old male.
- To analyze the natural history and growth patterns of CEH.
- To contribute to the limited knowledge base of this rare pulmonary disease.
Main Methods:
- Case report of a 76-year-old male with CEH.
- Review of relevant literature on CEH cases.
- Analysis of serial chest computed tomography (CT) scans.
- Calculation of lesion doubling time and volume change.
Main Results:
- The patient's CEH demonstrated an inconstant growth rate.
- The lesion's onset was estimated to be 8.2-11.0 years prior to the patient's death.
- The CEH in this case was not surgically resected, allowing observation of its natural course.
Conclusions:
- CEH growth is variable and can occur over many years.
- Further research and case accumulation are crucial for understanding CEH.
- Observing the natural history provides valuable data on CEH progression.
Abstract:
Chronic expanding hematoma (CEH) is a rare disease that is usually present as a large solitary pulmonary nodule. CEHs are slow growing, but processes underlying their development remain unknown. The present study herein reports the case of a 76-year-old male patient with CEH and discusses a number of CEH cases published in the literature. The majority of these previously described patients were Asians. The CEH in the present case was not a successfully resected one, but the patient's clinical course provided information concerning the natural history of the disease. During the clinical course, the patient underwent several chest computed tomography scans. For the present case report, the doubling time and volume change of the mass was calculated, which revealed that the lesion had an inconstant growth rate and that its onset was between 8.2-11.0 years before the patient succumbed to this disease. Accumulation of knowledge about this rare disease will help to elucidate it further.

Flail chest is a severe and potentially life-threatening condition characterized by the fracture of three or more adjacent ribs in multiple places. It is most commonly caused by direct impacts and trauma, such as motor vehicle accidents or injuries from a steering wheel impact. It can also occur due to falls in elderly individuals with osteoporosis, or assaults involving sharp objects.
