Chronic expanding hematoma: a late complication 45 years after thoracoplasty

Problematic Imaging Diagnostics of Musculoskeletal Gossypiboma with Chronic Expanding Hematoma Mimicking Malignant Lesion

Both musculoskeletal gossypibomas and chronic expanding hematomas have been rarely reported; the reports that do exist are usually case reports. Our objective is to demonstrate problematic imaging diagnostics of an unusual presentation mimicking a malignant lesion. We report the case of a 47-year-old man who underwent bone graft harvesting from the iliac crest for spinal fusion due to scoliosis at 18 years of age, and 29 years later, he developed a growing, painful tumor at the original donor site (a bone defect in the iliac crest). It was challenging to differentiate a hematoma from a malignant tumor based solely on clinical and radiological workup, including an ultrasound-guided needle biopsy focused on viable tissue. The definitive diagnosis of a gossypiboma with a chronic expanding hematoma was based on histopathological assessment after wide surgical resection-a chronic expanding hematoma with multiple foamy macrophages and giant cells engulfing foreign material (original surgical hemostatic sponge).

Chronic Expanding Hematoma on Latissimus Dorsi Free Flap Donor Site Grown Over 17 Years

ABSTRACT

The latissimus dorsi free flap (LDFF), that provides long vascular pedicle with rich vascularization and adequate bulk for maxillofacial defect coverage, is utilized in microvascular surgery for maxilla-mandibular reconstruction with high success rate, less morbidity, and ability to provide facial symmetry. In addition, it can reduce the risk of adjuvant therapies, such as radiotherapy. Seroma formation at the donor site following LDFF harvest has been reported as a common postoperative sequela. On the other hand, chronic expanding hematoma (CEH) in an LDFF donor site is a rare postoperative complication. In this case report, the authors describe a rare occurrence of a solidified CEH on an LDFF donor site in a male patient 17 years after mandible reconstruction surgery. For treatment, the patient underwent mass resection with drain placement and quilting suture, resulting in reduction of the hematoma and faster healing.
