Introducción: Los tumores de la región pineal constituyen un grupo heterogéneo de lesiones agrupadas más por su localización común que por su relación histológica. Pueden clasificarse en tumores de células germinales, del parénquima pineal, embrional y de estructuras adyacentes. Objetivo: Carac...
Introduction The pineal gland is a common location for intracranial germ cells, but
dermoids are not commonly observed in this area. In the present paper, we discuss the
clinical and radiological features as well as the treatment and outcome of this cyst in a
6-year- old child with a pineal dermoid cyst....
Introduction Hemangioblastomas of the pineal region or pituitary stalk are extremely
rare. Only two cases of hemangioblastomas involving the pineal region have been
reported, and four involving the pituitary stalk. The purpose of the present manuscript
is to describe an unusual case of supposed hemangiob...

ABSTRACT. Interest in anatomy dates from the earliest times. Such knowledge was acquired through dissections of animals and human corpses by many researchers. The macroscopic anatomy of the varied structures of the brain were identified over the centuries, and the predominating solid substance was seen a...
SUMMARY: Pineal gland calcification is the most common physiological intracranial calcification followed by the choroid plexus calcification. The objective of the study was to determine the prevalence of the pineal gland and choroid plexus calcification among the Iraqi population attending computed tomog...

Dentre os vários tipos de traumas, a avulsão dentária representa uma condição crítica por deslocar o dente de seu ambiente natural, expondo-o a um meio externo seco e contaminado, resultando na reabsorção da raiz que pode ser parcial ou total. Pouco tem sido estudado sobre os fatores sistêmicos ...

Pineal region tumors are uncommon among neoplasm of the central nervous system, with this region being the most heterogeneous in terms of histological types. Meningiomas are rarer still, but can be found at this site, with origins in either the velum interpositum or falcotentorial junction. Neuroimaging ...
Pineal cavernous angioma is a vascular malformation that has a prevalence lower than
1%. The etiology is debated. It is believed that it is originated from an autosomal
dominant inheritance or from radiotherapeutic treatment. Complete resection enables
the cure and prevents complications of the natural e...
Papillary tumor of the pineal region (PTPR) is a neuroectodermal tumor thought to
originate from cells of the subcommissural organ. Its oncologic properties are still
under investigation, as well as the most suitable therapeutic measures for this type of
neoplasm.We report the case of a 36-year-old woman...

Abstract The hypothesis of this study was that the peri-implant bone healing of the group of pinealectomized rats would differ from the control group. The samples were subjected to immunohistochemical, microtomographic (total porosity and connectivity density), and fluorochrome (mineralized surface) anal...
