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...

Middle meningeal artery (MMA) embolization has been performed to treat refractory chronic subdural hematoma (CSDH) with good reported outcomes. We have treated three cases of CSDH with MMA embolization to date, but there was a postoperative recurrence in one patient, which required a craniotomy for hematoma removal and capsulectomy. MMA embolization blocks the blood supply from the dura to the ...

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 ...

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,...

OBJECTIVE Organized hematoma of the maxillary sinus can develop by means of organization of hematoma in the unaerated maxillary sinus. To our knowledge, this is only the second article describing organized hematoma in the maxillary sinus. MATERIAL AND METHODS We have observed eight cases of organized hematoma of the maxillary sinus recently and here we describe the clinical features (using CT...

A 59-year-old male presented with a left organized subdural hematoma. The hematoma appeared as a homogeneous low density area on brain computed tomography and as hyperintense and isointense area on both fluid-attenuated inversion recovery and T2-weighted magnetic resonance (MR) imaging. Echo-planar diffusion-weighted MR imaging showed a crescent hyperintense area under the dura mater and an irr...
