INTRODUCTION The Abernethy malformation is a rare anomaly with a widely variable clinical presentation. Many diagnostic dilemmas have been reported. Nowadays, with the evolution of medical imaging, diagnosis can be made more easily, but management of patients with an Abernethy malformation is still open for discussion. CASE PRESENTATION In this case study, we describe a 34-year-old Caucasian ...

OBJECTIVES To determine the clinical presentation and treatment outcome of pediatric intracranial cavernous malformation (CM) in a single-centered institution. METHODS Clinical data review of 30 patients under 18 years-old who had undergone surgery for cavernous malformation from January 1993 to December 2011. RESULTS The Study Group included 18 males and 12 females (mean age: 8.7 years-old...

Malta Medical Journal Volume 28 Issue 02 2016 Abstract Neurosurgical procedures in cases of Type 1 Arnold Chiari Malformation (ACM) may result in a wide spectrum of complications. We report a case of a sixty-four year lady who underwent an elective posterior fossa decompression for Type 1 ACM. The procedure was complicated by syndrome of inappropriate anti-diuretic hormone secretion (SIADH) and...

We consider a family of two-dimensional nonlinear area-preserving mappings that generalize the Chirikov standard map and model a variety of periodically forced systems. The action variable diffuses in increments whose phase is controlled by a negative power of the action and hence effectively uncorrelated for small actions, leading to a chaotic sea in phase space. For larger values of the actio...
