This study aimed to develop a system of quantitative analysis of canine Chiari-like malformation and syringomyelia on variable quality MRI. We made a series of measurements from magnetic resonance DICOM images from Griffon Bruxellois dogs with and without Chiari-like malformation and syringomyelia and identified several significant variables. We found that in the Griffon Bruxellois dog, Chiari-...

The Abernethy malformation is a rare congenital malformation defined by the presence of an extrahepatic portosystemic shunt. Although most patients are asymptomatic, clinical encephalopathy is present in 15% of cases. We present a patient with type 2 Abernethy malformation, hyperammonemia, and encephalopathy. Shunt closure was performed successfully using interventional angiography; however, hy...

We report a case of type I Arnold-Chiari malformation that is very Introduction: peculiar because of its particular onset especially characterized by psychiatric symptoms. These symptoms were so prevailing that, for fifteen years, they masked the neurological aspects and the patient was treated with high doses of psychotropic drugs without any benefit. If the Arnold-Chiari malformation had been...

A case of a 14-year-old girl suffering from intense headaches is presented. At the first pediatrician's examination, patient had regular findings. Prolonged P100 wave latencies were found by testing visual evoked potentials. After further examination following repeated headaches, Arnold Chiari type I malformation was diagnosed. classified as downward displacement one or both cerebellar tonsils ...

BACKGROUND Acute porphyria and Arnold Chiari malformation are both uncommon genetic disorders without known association. The insidious onset, non-specific clinical manifestations, and precipitating factors often cause diagnosis of acute porphyria to be missed, particularly in patients with comorbidities. CASE REPORT A women with Arnold Chiari malformation type II who was treated with oxybutyn...

INTRODUCTION Chiari type I malformation (CM-I) is characterised by caudal ectopia of the cerebellar tonsils through the foramen magnum. This is associated with brain stem, high spinal cord, and cranial nerve compression phenomena. The most frequent symptoms are occipital headaches and dizziness. Less well-known symptoms are sleep disorders and nocturnal respiratory abnormalities. SOURCES MEDL...

OBJECT The choice of surgical technique for decompressive surgery in patients with Chiari I malformation is controversial. Good preliminary postoperative outcomes have been achieved in patients with Chiari I malformation (without syringomyelia) after using a dura-splitting technique. The authors evaluated safety, resource use, and early outcome after this surgery in patients without syringomyel...

Between January, 1981, and July, 1991, 17 infants under 1 month of age were admitted to The Hospital for Sick Children with the signs and symptoms of a Chiari II malformation. These patients' presentation included swallowing difficulty (71%), stridor (59%), apneic spells (29%), aspiration (12%), weakness of cry (18%), and arm weakness (53%). Decompression of the Chiari II malformation was perfo...

We aimed to describe a patient without Chiari malformation who was treated via craniocervical decompression and by creating cisterna manga with an autologous fascia graft, and who displayed a clinical and radiological improvement in the post-operative period. Syringomyelia is a chronic and progressive disease with cavitation and gliosis in the spinal cord. It is more common in adulthood and oft...
