Hemosiderin

07/01/2008 - "Dark Agouti rats from our colony consistently exhibited spontaneous focal hemorrhages at the vitread surface of the retina between postnatal days 3 and 6. Erythrocytes were subsequently cleared by macrophages, which accumulated hemosiderin. "
01/01/1992 - "Quantification of the hemosiderin content of alveolar macrophages improved the specificity of the diagnosis of diffuse pulmonary hemorrhage by BAL."
09/01/1984 - "Hemosiderin was rapidly cleared from the lungs following an acute pulmonary hemorrhage."
01/01/2022 - "However, previous studies have suggested the possible mechanism: cerebrospinal fluid (CSF) leaks into the epidural space through the ventral dural defect, and repetitive bleeding occurs from the epidural vessels that circulate back to the subarachnoid space through the dural defect, leading to hemosiderin deposition on the surface of the brain, the central nerves, and the spinal cord. "
05/01/2015 - "Recent diffusion tensor imaging (DTI) studies have demonstrated that leakage of hemosiderin into cerebrospinal fluid (CSF), which is caused by high-grade intraventricular hemorrhage (IVH), can affect cerebellar development in preterm born infants. "

12/01/2011 - "Routine histologic studies showed no seminiferous tubules in 18 cases (60%), fibrosis in all (100%), calcifications in 16 (53%), and hemosiderin deposits in 9 (30%). "
10/01/2022 - "Histology at 14 and 30 days revealed fibrosis with hemosiderin-laden macrophages replacing the ablated TD. "
08/25/2022 - "Laparoscopically, the peritoneum appeared grossly normal, but fibrosis and abundant hemosiderin deposition were noted on histology. "
07/01/2022 - "Vessels histopathologically corresponded to dilated vascular structures in the dermis, orange structureless areas to either dermal hemosiderin (patch/plaque stage) or dense cellular infiltration (tumours), bright white lines/structureless areas to dermal fibrosis and ulceration to loss of epidermis. "
06/01/2022 - "The cytoplasm was transparent or eosinophilic, and the interstitial fibrosis was accompanied by chronic inflammatory cell infiltration, hemosiderin deposition and foam cell aggregation. "

01/01/2009 - "Microsurgical removal of cavernous angiomas and surrounding hemosiderin plate tends to significant reduction or elimination of epileptic seizures and improved postoperative neurological status."
01/01/2021 - "Rats with acute symptomatic seizures showed more extensive lesions and hemosiderin deposits in the piriform cortex. "
01/01/2021 - "Animals with acute symptomatic seizures had more extended hemorrhagic lesions and hemosiderin deposits in the piriform cortex. "
10/01/2019 - "History of epileptic seizures at the time of surgery (OR, 7.61; 95% CI, 1.67-85.42; P = .003) and partial resection of the CA and/or of the hemosiderin rim (OR, 12.02; 95% CI, 3.01-48.13; P < .001) are independent predictors of uncontrolled seizures postoperatively. "
09/01/2014 - "Based on the satisfactory seizure outcome achieved, complete microsurgical excision in children is recommended for CMs presenting with seizures but removal of hemosiderin-stained areas seems to be unnecessary."

12/01/2012 - "Moreover, such online mapping can be helpful when removing the pericavernomatous gliosis while preserving functional structures, which can persist within the hemosiderin rim. "
09/01/2005 - "Brain MRI hyperintense (gliosis) or hypointense (hemosiderin) areas or both were assessed in the images of 135 adult TBI inpatients who completed a 2-year clinical, EEG, and MRI study protocol. "
10/01/1998 - "Biopsy samples and autopsy histopathological studies showed inflammatory cells, hemosiderin-laden macrophages, and astrocytosis. "
12/01/2022 - "Reactive gliosis and hemosiderin deposits in perilesional tissue in AVM and siderotic vessels in CCM were associated with seizure. "
12/01/2022 - "In AVM, hemosiderin deposition and gliosis in parenchyma (p=0.01) had significant association with seizure. "

11/01/2023 - "Two radiologists independently analyzed tumor size, vascular involvement, signal characteristics in T1- and T2-weighted sequences, the presence of hemosiderin, both microscopic and macroscopic fat content, enhancement patterns, and apparent diffusion coefficient (ADC) values derived from b-values of 1000 s/mm². "
09/16/2023 - "During the operation, it was found that the tumor originated from the dura mater and extensively invaded the surrounding brain tissue and skull, and the surrounding hemosiderin deposition was observed. "
01/01/2023 - "These tumors are less commonly calcified and may present with the "cap sign," with T2 hypointensity due to hemosiderin deposition. "
01/01/2023 - "Cytology revealed hemosiderin-laden macrophages suspicious for Brown's tumor. "
08/25/2022 - "Hemosiderin deposition was found in a small amount of tumor cells in 6 cases. "
