Dandy-Walker malformation (DWM) is a posterior fossa anomaly characterized by hypoplasia and upward rotation of the cerebellar vermis and cystic dilation of the fourth ventricle. The cyst of DWM rarely extends posteriorly to almost completely fill the entire posterior fossa, which mimics primary cerebellar agenesis, a cerebellar porencephalic cyst, and an arachnoid cyst due to the lack of clari...

PURPOSE In this study 30 patients with symptomatic epilepsy caused by cavernomas were investigated in a postoperative follow up study to assess predictors for postoperative outcome with respect to indications, time and approach of surgery. METHODS Thirty patients with cavernomas refractory to medical treatment were scheduled for surgery based on the findings of high-resolution MR imaging and ...

OBJECTIVE To determine if there is an association between fatty diet induced obesity and spleen enlargement by means of Cavalieri principle, unbiased stereological method and light microscopic examination. METHODS In this study, we used 16 adult female Sprague Dawley rats, weighing between 150-200 g. All animals were obtained from the Ataturk University Experimental Research and Applying Cent...

OBJECTIVES To describe the clinical details and follow up of children with idiopathic pulmonary hemosiderosis. DESIGN Retrospective case series. SETTING Pediatric chest clinic of a tertiary care hospital. SUBJECTS Children diagnosed as suffering from idiopathic pulmonary hemosiderosis (IPH). METHODS Charts of patients diagnosed as IPH were reviewed for clinical features and treatment re...

BACKGROUND Increases in hemosiderin-laden macrophages (HLM) are reported to be observed in idiopathic pulmonary fibrosis (IPF). According to a recent study, significant correlation between hemosiderin deposition in the lung tissue of IPF and pulmonary hypertension evaluated by echocardiography has been suspected. In this study, we aimed to evaluate whether HLM in bronchoalveolar lavage fluid (B...

revealed little or no hemosiderin in the tumor or bone marrow but revealed moderate to marked increases in the amount of hemosiderin in the spleen and liver of most of the chickens that were inoculated with tumor. Lymphoid tumor-bearing chickens developed a progressive hypoferremia, and there was a precipitous drop in the packed cell volume. An increase occurred in both serum iron-binding capac...

LTHOUGH FERRITIN has been shown to be present in many tissues of the body, the bulk of it is found in the cells of the liver, the spleen, and the bone marrow.”2 Ferritin aggregates with other cellular constituents, it is believed, to form insoluble complexes called hemosiderin.3 Ferritin and hemosiderin constitute the body’s storage depot of iron. Most of this iron supply, derived chiefly from ...

The purpose of this study was to characterize the effects of stimulated echo contamination on MR-based iron measurement derived from quantitative T2 images and develop a method for retrospective correction. Two multiple spin-echo (MSE) pulse sequences were implemented with different amounts of stimulated echo contamination. Agarose-based phantoms were constructed that simulate the relaxation an...

Iron and eosinophilic, argyrophilic spheroid structures of glycoconjugates are observed in the pallido-nigral system of human and nonhuman primates. In the present study, we map the localization and distribution of ferritin and hemosiderin and their relation to neutral and acidic (sulphated and carboxylated) glycoconjugates in human globus pallidus. We investigated tissues of human globus palli...

Radicular cysts are the most common inflammatory odontogenic cystic lesions. It originates from epithelial residues in periodontal ligaments secondary to inflammation. The pathogenesis involves the activation of epithelial cell rests of Malaseez after physical, chemical or bacterial injury. Microscopically, the cyst is thin with smooth or corrugated inner surface. The most common epithelial lin...
