The author reviewed medical records of 110 patients who underwent surgical clipping of cerebral aneurysm in order to determine the clinical and epidemiological characteristic of patients with hydrocephalus secondary to subarachnoid hemorrhage (SAH) during the period April 2007-2008. He concluded that a judicious indication of a shunt greatly influences the patient's recovery, despite the fact that this one is multifactorial.

The authors concluded in their study that deconstructive embolization of wide neck and fusiform aneurysms still remains a useful technique in selected cases. The clinical and angiographic criteria in the balloon test occlusion seem to predict accurately the tolerance of the parent vessel for its definitive occlusion in these challenging lesions. They reviewed retrospectively the clinical and radiographic data of 11 cases treated between 1995 and 2009.

Spinal metastasis from hepatocellular carcinoma is an uncommon but serious disorder, occurring in 1.2 to 3% of patients with hepatocellular carcinoma, which is a common malignancy in developing countries and although its extrahepatic spread is common especially to lung and lymph nodes, spinal metastasis is rare and only few reports have been described in the past.

The authors report a 37 year-old man with tension pneumoencephalus secondary to frontal sinus osteoma. He had history of headache and left hemiparesia. CT scan revealed a large volume of air entrapped in the right frontal lobe related to an osteoma in the frontal sinus. The osteoma eroded the posterior wall of the sinus and extended into the cranial fossa.
