Misoprostol is often used for termination of pregnancy in France and other countries. However, some pregnancies are continued after taking the drug and congenital malformations are known to be the consequence of fetal exposure to misoprostol, among them hydrocephalus. The type of hydrocephalus in case of misoprostol exposure is not known. ⋯ The possible physiopathologic implications of the drug regarding the genesis of this malformation are discussed.

Endovascular treated cerebral aneurysms have a greater recurrence rate compared with microsurgical clip ligation. Despite recent endovascular advances, microsurgical clip ligation might be the treatment of choice for certain previously endovascular treated recurrent aneurysms. We report on our single-center experience with 76 previously coiled and/or stent-coiled aneurysms. ⋯ Microsurgical clipping of previously endovascular treated recurrent aneurysms is an effective treatment with high obliteration rates. Previously stent-assisted coiling and intraoperative coil extraction are predictors of worse outcome and incomplete occlusion.

Spontaneous resorption of herniated lumbar disk was explained in the literature by different mechanisms, and multiple predictive factors for resorption were reported in numerous studies. The purpose of this study was to evaluate the phenomena of spontaneous resorption of herniated lumbar disk without surgery (mechanisms, predictive factors, expected time for resorption, and proper time for conservative treatment). ⋯ Spontaneous resorption of herniated lumbar disk can occur by different mechanisms (retraction, dehydration, and inflammatory mediated mechanism). Large and/or sequestrated disks are essential predictive factors for rapid spontaneous resorption. Furthermore, early clinical recovery is usually associated with quick resorption of the herniated disk.

Most gaseous lumbar pseudocysts have been previously reported to be located in the spinal canal and successfully treated by several therapeutic methods. By comparison, a gas-containing pseudocyst in the lumbar extraforaminal area is rare. Here, the authors report a case of symptomatic gas-containing cyst located in the lumbar foramen. It was successfully treated with unilateral biportal endoscopic (UBE) surgery. ⋯ A gas-containing pseudocyst in the lumbar foraminal area is not common. Combined use of preoperative magnetic resonance imaging and computed tomography can help diagnose a gaseous pseudocyst and differentiate other pathologies. A UBE technique that provides good operative visualization and delicate operative manipulation is a less invasive therapeutic method to treat a foraminal gas-containing pseudocyst.
