Endoscopic Sinus Surgery for the Treatment of Organized Hematoma of the Maxillary Sinus

Organised haematoma of the maxillary sinus in patients with chronic renal failure

“…The lesion itself shows intermingled, heterogeneous areas of low, intermediate and high signal intensity, on both T1-and T2-weighted images. 1 The sinus mucosa surrounding the lesion is well enhanced on T1-weighted images with contrast, and there is high signal intensity on T2-weighted images. The central part of the lesion shows low signal intensity on T1-weighted images and high signal intensity on T2-weighted images, while the peripheral rim of the lesion has low signal intensity on T2-weighted images.…”

“…1 Chronic renal failure (CRF) patients are at an increased risk of bleeding due to platelet dysfunction caused by uraemia and the use of anticoagulants during dialysis. 2 Herein, we present two cases of organised haematoma of the maxillary sinus in patients with CRF.…”

The increasing incidence of paranasal organizing hematoma: a 20-year experience of 23 cases at a single center

“…He described it as a hemorrhagic, non-neoplastic mass causing mucosal swelling and bony destruction. This disease has had many names, including "organizing hematoma, " "organized hematoma, " "hematoma of the maxillary sinus, " "hemorrhagic pseudotumor, " and "maxillary sinus hematoma" (2)(3)(4)(5) . ted that 39.7% of patients exhibited bony destruction (6) .…”

Three Cases of Organized Hematoma of the Maxillary Sinus: Clinical Features and Immunohistological Studies for Vascular Endothelial Growth Factor and Vascular Endothelial Growth Factor Receptor 2 Expressions

“…An organized hematoma (OH) is rare, mainly arises from the maxillary sinus, and is a nonneoplastic, hemorrhagic lesion causing mucosal swelling and bone thinning [ 1 ]. The first report of this lesion was introduced in the Japanese literature as a “blood boil” by Tadokoro in 1917, and it is relatively difficult to differentiate it from a malignant lesion causing mucosal swelling and bone thinning [ 2 , 3 ]. Thus far, many reports have described the imaging findings and/or clinical course, but the pathogenesis of the disease is unclear.…”
