چکیده
Objective. To characterize features of organized hematoma (OH) that may cause considerable diagnostic difficulties. Study Design. Case series with chart review. Setting. Tertiary medical center. Subjects and Methods. Eighty-four patients with pathologically confirmed OH over a 10-year period were retrospectively reviewed for clinical features, imaging findings, pathologic characteristics, and treatment modalities. Results. This study included 39 males and 45 females who presented with frequent epistaxis and nasal obstruction. There were 62 (74%) patients .40 years old (mean, 50; range, 981). OH mainly originated in the maxillary sinus (n = 82) or nasal cavity (n = 2) unilaterally, and most were expansile masses (n = 73) that extended into nasal cavity (n = 71) or choanae (n = 17). Several lesions were locally aggressive and simulated a malignant process that involved the ethmoid sinus (n = 22), orbit (n = 11), pterygopalatine fossa (n = 16), infratemporal fossa (n = 9), cheek (n = 3), and hard palate (n = 3). Internal architecture on computed tomography (CT) scans showed OH with expansile remodeling of the maxillary wall (82.1%) and smooth bony destruction (70.2%), whereas T2-weighted magnetic resonance (MR) images showed inhomogeneity with a notable hypointense peripheral rim in all lesions. CT and MR contrast-enhanced images revealed patchy heterogeneous enhancement that could be interpreted according to histopathologic findings of hemorrhage and neovascularization. OH was successfully removed with endoscopic surgery, although 5 cases recurred. Conclusions. OH can be successfully treated by endoscopic surgery. CT and MR examination provide characteristic findings for prediction and careful surgical planning.

Five cases of pathologically proven organized intracerebral hematoma with recent hemorrhage are reported. The hemorrhages were spontaneous, were located in deep structures of the brain, and presented without a clinical history of hypertension or trauma. No underlying causes of the hematomas were identified histologically. Various computed tomographic (CT) patterns of recurrent hemorrhage in an ...

متن کاملOrganized hematoma of temporomandibular joint
Organized hematoma is a pseudo-tumorous lesion mostly occurs at sinonasal cavity and often confused with malignant neoplasm. The initiation of this lesion is blood accumulation, probably due to trauma, and this hematoma develops into organized hematoma as it encapsulated with fibrous band and neo-vascularized. Since it is uninformed at temporomandibular joint (TMJ) region, imaging diagnosis mig...
متن کاملExpansile organized maxillary sinus hematoma: MR and CT findings and review of literature.
An organized hematoma is a chronic state of fibrotic tissue surrounding a hemorrhage. A mass lesion resulting from hematoma in the maxillary sinus was first reported in 1917, and the term, "blood boil," was clinically coined from such features as encapsulated blood and locally aggressive behavior. Subsequently, others have reported lesions with a similar appearance and clinical course, and now,...
