ABSTRACT
Arnold-Chiari type I malformations usually manifest clinically with short-lasting headaches typically involving the occipital-nuchal region and precipitated by the Valsalva maneuver, coughing, sudden postural change, or physical exertion. We describe the case of an adult patient who presented with symptomatic trigeminal neuralgia caused by an Arnold-Chiari type I malformation. Unlike previous cases, the malformation involved the trigeminal ophthalmic division alone.

BACKGROUND/AIM: The lateral sinus (LS) is composed of the transverse sinus (TS) and sigmoid sinus (SiS). METHODS: We studied the clinical pattern of complete or isolated LS thrombosis in 22 consecutive patients. RESULTS: Isolated LS thrombosis patients had a more severe clinical presentation, and more frequent intracranial hemorrhages and seizures. CONCLUSION: These data suggest that partial involvement of the LS in the thrombotic process may cause more severe clinical symptoms.
