“…1 Without knowledge of the typical clinical presentation and the complete study of imaging findings, the entity tends to be clinically and radiologically confused with neoplastic processes and even malignancy. 2 This entity has been described in the literature in different terms, including cavernous hemangioma, [3][4][5][6][7] organized or organizing hematoma, [8][9][10][11] hematoma-like mass of the maxillary sinus, 12 and SAP. 1,2,13,14 This lesion is difficult to remove en bloc and is easily broken during excision, so the sampling inconsistencies related to lesional fragility are likely responsible for the wide variation in pathologic description and terminology.…”

“…3,[8][9][10][11] The conventional MR imaging findings of SAP, however, have been described in only a few articles. 2,4,8,13 In addition, its features on DCE MR imaging and DWI have not been systematically reviewed, to our knowledge.…”

“…On the other hand, the fibrous capsule around the hematoma prevents the absorption and facilitates its progressive expansion. Various causes can lead to the initial blood collection, such as bleeding diathesis, postoperative complication, radiation therapy and trauma [1,4,5].Our patient, despite our persistent question, did not report us a neck injury, while the hematological tests were normal Many authors have reported several cases of organized hematoma in the head and the neck (Table 1). It is appeared in all age groups (2-85 years) with a slight predominance in males (57%).…”

“…The term "organizing" explains the histologic findings such as fibrous tissue, neovascularization and extravasated red blood cells. The formation of a fibrous capsule around the hematoma prevents its absorption and allows for recurrent intracapsular bleeding and progressive expansion [1]. The organizing hematoma was first described by Tadokoro in 1917 [2].…”

“…CT findings of sinonasal organized hematoma are rather nonspecific [7,8]; the reported CT appearance of the disease included a large expansile mass with bony erosion of the maxillary sinus and heterogeneous high attenuation on contrast-enhanced CT.…”
