Unlabelled: Meningiomas are the most frequent met intracranial tumors. Many authors tried to order them according to location, origin and histopathologic type.
Material And Method: Our study is focused on posterior fosa meningiomas, initially classified according to their origin based on IRM and surgical findings in order to identify correlations between demographic data, topographic tumor origin and anatomopathologic characteristics for each subgroup. 35 posterior fosa meningioma patients that have been subject to neurosurgery in Iaşi "Prof.Dr. N. Oblu" Hospital Neurosurgery Clinic between January 1st 2005 and December 1st 2009 were assessed.
Results: In our study group the majority of patients were females, with an average age in their early 60's. Benign meningiomas (1st degree) represented the unique subtype in tumors located in cerebellum convexity and foramen magnum. Other locations have different characteristic subtypes (fibrous vs. angiomatous meningioma).

Division of Colon and Rectal Surgery, Mayo Clinic, Rochester, Minnesota.
Background: Primary tumors of the ischiorectal fossa are rare and comprise a wide array of pathologies with varying malignant potential. Because of the low prevalence, there is a paucity of data in the literature. This article presents a case series on the management of ischiorectal fossa tumors.

Background: Lateral-type posterior fossa ependymomas are a well-defined subtype of tumours both clinically and pathologically, with a poor prognosis. Their incidence is low and surgical management is challenging. The objective of the present work is to review our series of lateral-tye posterior fossa ependymomas and compare our results with those of previous series.

Department of Orthopedics, First Affiliated Hospital of Zhengzhou University, Zhengzhou, Henan, PR China.
Background And Aim: Direct posterior reduction and manipulation of the C joints, accompanied by placement of spacers, is the state-of-the-art technique for treating basilar invagination (BI) and atlantoaxial dislocation (AAD). The hindrance of occiput to reaching up to the true atlantoaxial facets (AAF) during the surgery remains challenging for cage placement. The aim of this study was to explore an objective and precise method of measuring the effect of the hindrance of occiput to reaching up to the true AAF and cage placement during surgery.

Craniopharyngiomas are benign epithelial tumors which may very occasionally recur in ectopic locations. We present two cases of ectopic recurrence, both in the posterior fossa, and provide a review of the literature with basic statistics. Two patients admitted to our institution with posterior fossa lesions underwent gross total resection.

Dis Colon Rectum
December 2022
Department of Abdominal Surgery, University Medical Center Groningen, Groningen, The Netherlands.
Background: Phenolization of pilonidal sinus disease has been shown to have advantages over radical excision with regard to short-term outcome; however, long-term outcomes are essentially lacking.
Objective: The aim of this randomized controlled trial was to compare the long-term outcome of pit excision and phenolization of the sinus tracts vs radical excision with primary wound closure in pilonidal sinus disease.
Design: Single-center, randomized controlled trial.
