Colloid cysts account for approximately 2% of primary brain tumours and the majority of cases are identified in the fourth and fifth decade. They are small, gelatinous neoplasms lined by a single layer of mucin-secreting columnar epithelium that are thought to arise from errors in folding of the primitive neuroepithelium. They develop in the rostral aspect of the third ventricle in the foramen ...

BACKGROUND/AIM The major one among the procedures for evaluating changes in the thyroid nodules is fine needle aspiration biopsy (FNAB). Thyroid scintigraphy is commonly used in diagnostic algorithm of nodules. Less than 5% of examined nodules show to be malignant. Scintigraphically, nodules could be classified as functional and nonfunctional. It is estimated that the risk of malignancy in nonf...

To review recent advances in endoscopic techniques for treating intraventricular lesions via transcortical passage. Articles in PubMed published since 2000 were searched using the keywords 'endoscopy,' 'endoscopic,' and 'neuroendoscopic.' Of these articles, those describing intraventricular lesions were reviewed. Suprasellar arachnoid cysts (SACs) can be treated with ventriculo-cystostomy (VC) ...

OBJECTIVE Endoscopic resection of colloid cysts has been performed as an alternative to microsurgical resection and stereotactic aspiration since 1982. To date, there are limited published studies comparing these procedures. In this study, we present the largest series of endoscopic resections published to date and compare outcomes to a cohort of microsurgical resections performed at the same i...

introduction: the lymphatic system provides one of the main paths for the spread (metastasis) of cancer from one part of body to another. hodgkin’s diseases, lymphocytic leukemia, various metastatic disease and many lymph node disorders can be assessed by lymphoscintigraphy. radionuclide lymphoscintigraphy has been used for many years to define lymphatic drainage of melanoma. the most common ra...

The patient is a 55-year-old female with a history of multinodular goiter. She was followed for several years for a dominant left-sided superior pole thyroid nodule. Several prior fine needle aspiration biopsies had been performed. All were consistent with the diagnosis of degenerative colloid nodule. Eventually she developed symptoms of intermittent choking and shortness of breath and presente...

A series of twelve cases, all of whom had received surgery for the removal of a colloid cyst in the third ventricle, was examined on a series of memory tests. The only consistent predictor of poor memory performance that could be detected from MRIs was the presence of bilateral interruption of the fornix, which occurred in three of the subjects. Although these three cases were poor on tests of ...

OBJECTIVE Prevalence of cysts and tumors related to impacted third molars has been considered important because the risk justifies prophylactic extraction. This retrospective study aimed to evaluate the prevalence of cysts or tumors associated with impacted mandibular third molars (IMTMs) according to patients' age and gender. METHODS Over the period from August 2006 to August 2011, 20,802 th...
