Rupture of a chronic expanding hematoma of the thorax into lung parenchyma

Abstract

, emphasizing a possible complication of en bloc resections involving the vertebral bodies, especially after chemotherapy, radiotherapy, or both, might prompt the thoracic surgeon to evaluate a possible solution of continuity of the dura mater during extended lung resections.

Extrathoracic protrusion of a chronic expanding hematoma in the chest mimicking a soft tissue tumor

“…[3][4][5] Labadie and Glover, when proposing a mechanism for the expansion seen in CEHs, 6 theorized that the breakdown of leukocytes, hemoglobin, platelets, and fi brin results in an infl ammatory process that effectively damages the capillaries of the capsule, increasing the permeability of the vascular wall and causing bleeding from dilated microvessels underneath the fi brous capsule. Despite the calcifi cation of the capsule, it seems that a small degree of elasticity exists, which is the reason hematomas usually expand over a long period of time.…”

“…These lesions are diffi cult to differentiate from soft tissue sarcomas or other malignancies because sarcomas can also exhibit hemorrhagic and cystic changes radiologically. [5][6][7] FDG-PET imaging is increasingly used in clinical oncology because it allows functional imaging of a variety of tumors. Generally, high-grade sarcomas have higher SUVs than benign lesions.…”

“…2,5 Hanagiri et al reported that the surgical procedure should be complete resection because incomplete resection might result in massive bleeding from the hypervascular subcapsular lesion. 2 However, complete resection would not have been possible without pleuropneumonectomy, which the 77-year-old patient would not have survived.…”

“…2 CEHs can be misdiagnosed as malignant tumors because of their size and slowly progressive enlargement. [3][4][5] We report a rare case of extrathoracic protrusion of a CEH mimicking a soft tissue sarcoma originating from the chest wall.…”

Sudden Death Due to Recent Hemorrhage From an Intrathoracic Chronic Expanding Hematoma

“…Most cases have been reported in Japan in part because CEH is a long‐term complication of tuberculosis. Progression of intrathoracic CEH with expansion of the hematoma results in various symptoms due to adjacent organ compression and may cause fatal complications . Surgical treatment as early as possible is recommended to prevent such complications.…”
