Case ReportsDural arteriovenous fistulas of the cavernous sinus with onset of intracerebral haemorrhage mimicking hypertensive putaminal hemorrhage.
We describe a patient with dural arteriovenous fistulas of the cavernous sinus (CS-dAVFs) who developed an intracerebral haemorrhage (ICH) mimicking hypertensive putaminal haemorrhage. Drainage into the superior ophthalmic vein (SOV) and inferior petrosal sinus (IPS) was not demonstrated on cerebral angiography, and only cortical venous reflux into the Sylvian vein was observed. In cases of venous drainage concentrated on the Sylvian vein, CS-dAVFs could indicate ICH with radiological appearance resembling putaminal haemorrhage.

Trigeminal neuralgia is a common cause of facial pain, characterized by shock-like pain affecting one or more branches of the trigeminal nerve. When conservative treatment fails and microdecompression is not indicated, percutaneous procedures are helpful. This percutaneous approach is done by a puncture up to the Gasserian ganglion, through the foramen ovale. Although simple and safe, this puncture demands some expertise from neurosurgeons. For that, a partnership between neurosurgeons and bio-engineers has developed a model for foramen ovale puncture, allowing practice for residents and young neurosurgeons. ⋯ This model for foramen ovale puncture training has demonstrated valuable help for initial practicing of this common neurosurgical procedure, particularly in centers where there are not many cadavers available for training.

Quality of life after treatment for incidental, unruptured intracranial aneurysms.
Discovering an intracranial aneurysm may profoundly affect the patient's quality of life. Patients living with unruptured and untreated aneurysms often report symptoms of anxiety and depression. There are few trials studying the quality of life after treatment of unruptured intracranial aneurysms. We aimed to compare the quality of life and symptoms of anxiety or depression after endovascular coiling or open surgery clipping of unruptured intracranial aneurysms, in patients with no prior subarachnoid haemorrhage. ⋯ Quality of life after treatment does not seem to be a strong argument for choosing one modality of treatment over the other in patients with unruptured intracranial aneurysms. There are no significant differences in the quality of life of patients successfully treated using endovascular technique and patients who underwent craniotomy and clipping. We speculate that the low quality of life scores are due to factors unrelated to the aneurysms. The scores possibly reflect characteristics of a patient group where incidental aneurysms are more frequently diagnosed while undergoing extensive imaging procedures due to unrelated symptoms.

Knowledge of segmental innervation of skeletal muscles is essential for diagnosing lumbar radiculopathy. Myotomes and dermatomes are traditionally thought to be innervated by a single spinal segment, but experimental studies have shown that this pattern of segmental innervation allows considerable overlap. ⋯ We describe a patient in whom overlap in segmental innervation complicated adequate diagnosis of a recurrent lumbar hernia. Further, we present an outline of electrophysiological and anatomical studies on segmental innervation.

Myelocystoceles are rare lesions. Rarer still are thoracic myelocystoceles. Two patients with thoracic myelocystoceles are being reported. ⋯ Surgery in both these patients did not produce any change in the neurological status. The importance of recognizing thoracic myelocystoceles, their clinical presentation, embryology, value of MR myelography in the diagnosis and role of surgery are discussed. The differences between terminal myelocystoceles and thoracic myelocystoceles are also highlighted.
