Dural Arteriovenous Fistulas

Idiopathic occlusion of nearly all cerebral venous sinuses in association with the widespread formation of dural arteriovenous fistulas (AVF) is an extremely rare condition. The cause-and-effect relationship between thrombosis and AVF is not known, but a disturbance in venous flow and distant stagnation has been mentioned as probable pathomechanisms. We introduce a patient that was misdiagnosed as Parkinson's disease and treated accordingly for weeks. Then, rapidly-progressive dementia and shortly after that, an intracerebral hemorrhage occurred, and the diagnosis was established after Magnetic Resonance Imaging and Angiography. There were a whole venous sinus system thrombosis and the formation of numerous dural arteriovenous fistulas. The mechanism and diagnostic nuances are described in this paper, and the treatment options and prognosis are discussed.

Spinal Dural Arteriovenous Fistulas

Although more prevalent in males in the 6th and 7th decade of life, spinal dural arteriovenous fistulas (SDAVFs) are an uncommon cause of progressive myelopathy. Magnetic resonance imaging and more recently Gd bolus MR angiography have been used to diagnose, radiographically define, and preprocedurally localize the contributing lumbar artery. Three-dimensional myelographic MR imaging sequences have recently been developed for anatomical evaluation of the spinal canal. The authors describe 3 recent cases in which volumetric myelographic MR imaging with a 3D phase-cycled fast imaging employing steady state acquisition (PC-FIESTA) and a 3D constructive interference steady state (CISS) technique were particularly useful not only for documenting an SDAVF, but also for providing localization when CT angiography, MR imaging, MR angiography, and spinal angiography failed to localize the fistula. In a patient harboring an SDAVF at T-4, surgical exploration was performed based on the constellation of findings on the PC-FIESTA images as well as the fact that the spinal segments leading to T-4 were the only ones that the authors were unable to catheterize. In a second patient, who harbored an SDAVF at T-6, after 2 separate angiograms failed to demonstrate the fistula, careful assessment of the CISS images led the authors to focus a third angiogram on the left T-6 intercostal artery and to perform superselective microcatheterization. In a third patient with an SDAVF originating from the lateral sacral branch, the PC-FIESTA sequence demonstrated the arterialized vein extending into the S-1 foramen, leading to a second angiogram and superselective internal iliac injections. The authors concluded that myelographic MR imaging sequences can be useful not only as an aid to diagnosis but also for localization of an SDAVF in complex cases.

ABSTRACT Creutzfeldt-Jacob disease (CJD) is a rare condition caused by a pathogenic prion protein that evolves with rapidly progressive dementia and death. The clinical presentation may sometimes be misleading. Magnetic Resonance Imaging (MRI) aids diagnosis with patterns that can guide or confirm clinical hypotheses. Two cases of rapidly progressive dementia with ataxia, myoclonus and restricted diffusion on MRI in cortical/basal ganglia are presented to draw attention to CJD.

Dandy–Walker syndrome associated with syringomyelia is a rare condition, with few reports of adult cases. We describe an adult case of Dandy–Walker syndrome with concomitant syringomyelia. A 33-year-old man presented with a 3-month history of walking instability, numbness in the hands, memory deterioration, and urinary incontinence. A physical examination showed a positive Romberg sign. Brain computed tomography and magnetic resonance imaging showed hydrocephalus, a cyst in the posterior fossa, absence of the cerebellar vermis, hypoplasia of the corpus callosum and cerebella, and syringomyelia. All of these symptoms were consistent with the diagnosis of Dandy–Walker syndrome. Surgery involving arachnoid adhesiolysis and endoscopic third ventriculostomy was performed. At the 6-month follow-up, the symptoms were completely relieved. Magnetic resonance imaging showed that syringomyelia was greatly reduced and the hydrocephalus remained unchanged. Dandy–Walker syndrome with concomitant syringomyelia in adults is exceedingly rare. Early diagnosis and appropriate surgical treatment of this condition should be highlighted. Combined arachnoid adhesiolysis and endoscopic third ventriculostomy may be an effective approach.

Abstract Background Absence of the pericardium is a rare congenital defect with an approximate incidence of <1/10 000. We review a case of complete pericardial agenesis in a symptomatic patient with gross cardiac mobility, for which pericardial reconstruction was undertaken successfully. Case summary A 24-year-old otherwise fit and well patient, with debilitating exertional chest pain was found to have complete pericardial agenesis on the left side and on the diaphragmatic surface. There was gross cardiac mobility demonstrated on cardiac magnetic resonance imaging. His pericardium was reconstructed surgically using Gore-tex® patches. There were no complications, and the patient was discharged 8 days later. Three months later at follow-up, the patient required no analgesia and has had complete resolution of his chest pains. Discussion Congenital hemi-pericardial agenesis is a very rare condition which often remains undetected due to its asymptomatic nature. It is important to consider this as a differential diagnosis of exertional chest pains. Cardiac magnetic resonance imaging remains the investigation of gold standard. There is no consensus on whether surgical intervention in symptomatic or asymptomatic patients has any prognostic value. However, we have demonstrated that by reconstructing the pericardium in a highly symptomatic patient, there has been a resolution in size of a previously dilated right ventricle and most importantly an improvement in quality of life.

Abstract Background The herniation of the ureter into the inguinal canal is a rare condition, but probably underreported. Acquired nephroptosis could cause herniation of the ureter and, therefore, when diagnosed, a full study of the urinary tract should be performed especially in patients with inguinal hernia. Case presentation We present the case of an 86-year-old white man with a herniated ureter likely caused by acquired nephroptosis presenting with acute urinary retention, documented with magnetic resonance imaging for the first time. Conclusions The Fast Imaging Employing Steady State Acquisition sequence on magnetic resonance imaging, for many reasons, could allow correct evaluation of the urinary tract, especially in cases of renal dysfunction that contraindicate the use of intravenous contrast agents.
