Cystic lesions were found in the telencephalic germinal layer of 12 newborn babies. According to their location, the cysts could be divided into three groups: anterior, middle or thalamostriate, and posterior. The histological appearance of all cysts was essentially the same, but in three cases the germinal layer had a peculiar alveolar type of microcystic degeneration. A constant feature was t...

The arachnoid granulations of adult individual of both sexes were studied through scanning electron microscopy. The dura mater and arachnoid meninges of individuals were collected at the Service of Death Verification of São Paulo - USP and fixed in Karnovsky solution. After this period the material was prepared for analysis in electron microscope. Our results demonstrated that the arachnoid gra...

We present a case of tracheobronchial involvement in Crohn's disease, associated with respiratory failure leading to mechanical ventilation. Bronchoscopy revealed small, diffuse, whitish granulations and erythematous mucosa. Histopathology disclosed ulcerative bronchitis and noncaseating tuberculoid granuloma. The patient improved under a 6 week oral corticosteroid treatment followed by inhaled...

Duodenal tuberculosis is a rare clinical entity. The authors report and emphasize the lack of special clinical, radiological and endoscopic signs of duodenal tuberculosis. The diagnosis is affirmed, at laparotomy, out of the findings of peritoneal granulations or histology of lymphatic nodes. We report our experience of two cases of duodenal tuberculosis presenting with proximal intestinal obst...

The textbook view that projections of the arachnoid membrane into the cranial venous sinuses represent the primary cerebrospinal fluid (CSF) absorption sites seems incompatible with many clinical and experimental observations. On balance, there is more quantitative evidence suggesting a function for extracranial lymphatic vessels than exists to support a role for arachnoid villi and granulation...

ObjectiveTo determine whether the ooplasm granulation patterns of donor oocytes, like those oocytes from poor-prognosis patients, are predictive in vitro fertilization (IVF) outcomes.DesignRetrospective cohort study.SettingAcademically affiliated private clinical infertility and research center.Patient(s)770 fresh 381 vitrified-thawed metaphase II young donors (aged 21.0–34.6 years) used for IV...

We read with great interest the article by Arjona et al concerning a patient with intracranial hypertension (ICH) and giant arachnoid granulations (GAG). The patient was a non-obese male without known risk factors for ICH apart from left transverse sinus hypoplasia and several GAGs in both transverse sinuses. The authors suggested that arachnoid granulations (AGs) might be responsible for ICH b...
