Case Reports
Subdural effusions in the posterior fossa associated with spontaneous intracranial hypotension.
Misdiagnosis of spontaneous intracranial hypotension remains a problem, despite increasing recognition. ⋯ Subdural effusions in the posterior fossa can be identified by T2-weighted axial MR imaging, and are useful for the diagnosis of spontaneous intracranial hypotension and for verifying the effectiveness of treatment.

Invasive monitoring for the investigation of medically intractable epilepsy may be associated with undesirable morbidity. We performed a review of our recent experience to determine the incidence of major complications. ⋯ In comparison with previously published literature on the topic, the major complication rate in this group of patients appears to be low.

Reversible segmental cerebral vasoconstriction (RSCV) is a recognizable clinical and radiographic syndrome consisting of thunderclap headache with or without focal neurological symptoms combined with reversible segmental vasoconstriction of proximal cerebral blood vessels. ⋯ RSCV should be considered in a child with thunderclap headache.

Different strategies have been employed to recanalize acutely occluded middle cerebral and internal carotid arteries (ICA) in the setting of acute stroke including intravenous and intra-arterial tPA. However, pharmaceutical thrombolysis alone, may not be effective in patients with a large amount of clot volume (complete M1, terminal internal carotid artery). We report our initial experience with endovascular clot disruption using a soft silicone balloon in addition to intravenous or intra-arterial thrombolysis with tPA. ⋯ Clot angioplasty can potentially shorten recanalization times in well-selected patients and can be an effective complimentary procedure in patients with tPA resistant clot. Angioplasty can be performed with a very low complication rate using the technique described and may be associated with good outcomes.

To analyze our experience with a second radiosurgical treatment for brain arteriovenous malformations (BAVMs) after an unsuccessful first radiosurgical treatment. ⋯ Retreatment of BAVM using a second radiosurgery procedure is a safe and effective option that offers the same rate of success as the initial radiosurgery and an acceptable risk of radiation-induced complication.
