BACKGROUND The Chiari Malformation I (CMI) is a disorder of uncertain origin that has been traditionally defined as downward herniation of the cerebellar tonsils through the foramen magnum. The anomaly is a leading cause of syringomyelia and occurs inassociation with osseus abnormalities at the craniovertebral junction. In contrast to other Chiari malformations, CMI tends to present in the seco...

The cough/laugh syndrome is characterized by the onset of severe headache immediately after an episode of coughing, laughing, or straining. It has been associated with pathologic changes in the posterior fossa, in particular, cerebellar tonsillar herniation or ectopia [1-3]. MR imaging is important in the evaluation of craniocervical anomalies, particularly Chiari malformations [4, 5]. We prese...

The Budd-Chiari Syndrome is associated with hepatic venous outflow obstruction. This syndrome is rare in infants and children. As this syndrome is uncommon, especially in the paediatric age group, misdiagnoses and delays in the diagnosis are frequent. A high index of clinical suspicion along with a radiological aid and a histopathological correlation can lead to an early diagnosis and an approp...

Budd-Chiari Syndrome is an uncommon condition characterized by clinical features related to hepatic venous outflow obstruction resulting either from thrombotic or non-thrombotic causes. Presentations may vary asymptomatic acute fulminant failure. A meticulous history, examination and imaging studies are invaluable for a prompt diagnosis initiation of time-sensitive treatment. This report presen...

CASE REPORT We present a patient with bilateral Terson's syndrome after brainstem surgical decompression as treatment for her Arnold-Chiari I malformation. We have studied and compared the progression of preretinal hemorrhage after Nd:YAG laser treatment of the right eye and observation of the left, and also the formation of an epiretinal membrane in the left eye. DISCUSSION Treatment of Ters...
