Real-time neuronavigation with high-quality 3D ultrasound SonoWand in pediatric neurosurgery.
Intraoperative ultrasound (IOUS) serves as a basic imaging tool in neurosurgery. However, its low quality and difficulty in interpreting the images make its use as a resection control tool and navigation system cumbersome. We present our experience using a high-resolution 3D IOUS system combined with a navigation system in pediatric cranial surgery. ⋯ The indications for IOUS were preoperative navigation to define the skin incision and exact craniotomy site, and for real-time neuronavigation and resection control during tumor removal. The added time per case was short and no technical difficulties were encountered. High-resolution 3D IOUS combined with navigation systems has advantages for the pediatric neurosurgical population, including both real-time basic navigation and improved resection control.

Case ReportsPosterior fossa dermoid cyst in a patient with Goldenhar syndrome.
A 7-year-old boy with Goldenhar syndrome was diagnosed to have a posterior cranial fossa dermoid cyst. The presence of such a combination of clinical entities has not been reported earlier. The embryonic dysgenesis causing midline posterior fossa dermoid and other anomalies observed in Goldenhar syndrome occur between the third and fifth week of intrauterine life and are probably interrelated. This report emphasizes the need for a high index of suspicion and the value of cranial imaging in a case with Goldenhar syndrome.

Case ReportsPostoperative brain stem tension pneumocephalus causing transient locked-in syndrome.
The incidence of pneumocephalus after supratentorial craniotomy has been reported to be as high as 100%. However, transformation of postoperative pneumocephalus into tension pneumocephalus (symptomatic intracranial air) is a rather rare phenomenon. ⋯ We hereby report on a patient who developed brain-stem tension pneumocephalus in the early postoperative period after posterior fossa craniotomy for an exophytic brainstem astrocytoma, operated in the prone position. A complete locked-in syndrome resolved following surgical relief of the trapped air.

Case ReportsGiant malignant nerve sheath tumor of lumbosacral plexus with intraspinal extension in a child with neurofibromatosis type 1.
Malignant peripheral nerve sheath tumors (MPNSTs) are the leading cause of death in young adults and are one of the most frequent non-rhabdomyosarcomatous soft tissue tumors in pediatric age. These tumors usually occur in young adults from a previously recognized neurofibroma, neurofibromatosis type 1 (NF1), with a noted change in size and pain. This child reached the age of 10 without the presence of the more commonly seen manifestations of NF1. Pseudoarthrosis in children has a high rate of association with NF1, and in this case diagnosis of NF1 was supported by development of MPNST in a pre-existing plexiform neurofibroma.

Case ReportsTransorbital orbitocranial penetrating injury due to bicycle brake handle in a child.
Transorbital orbitocranial penetrating injuries (TOPI) are relatively rare and can be caused by a variety of unusual objects. Diagnosis of TOPI should be based on a detailed history and evaluation of available investigations as the penetrating injury may be overlooked. In the present case, a child sustained a penetrating injury with the brake handle of a bicycle due to the accidental fall of the bicycle on him and was managed conservatively.
