Case Report - Pediatric intramedullary schwannoma without neurofibromatosis
Pediatric intramedullary schwannoma without neurofibromatosis is
extremely rare with only five cases reported so far. We present this
rare finding in an 8-year-old boy who presented with a sudden onset of
weakness in all limbs. An intraoperative diagnosis of schwannoma
enabled us to carry out a total excision of the tumor, which resulted
in near complete recovery at 18 months follow-up. Although rare, this
diagnosis should be considered when a child presents with a solitary
intramedullary tumor, since its total resection can be achieved

A new minimally invasive tubular brain retractor system for surgery of deep intracerebral hematoma
Access to deep-seated brain lesions with traditional fixed and rigid
brain retractors can be difficult without causing significant trauma to
the surrounding brain. Tubular retractors offer an advantage of low
retracting pressure. We developed a new inexpensive and simple tubular
retractor which requires very small cortisectomy. The new tubular
retractor was made up of silicone with inner diameter of 15, 18 and 23
mm and outer diameter of 17, 20 and 25 mm, respectively. This tube (1
mm thick) was cut in longitudinal direction. It was folded to make a
small-diameter tube so that it could be introduced through a small
cortisectomy. Margins of cortisectomy were gently and slowly retracted
by Killian nasal speculum. Folded retractor, held by tissue forceps,
was introduced inside the opened Killian nasal speculum. Tissue forceps
and nasal speculum were removed leaving tubular retractor in place,
which comes back to its normal tubular configuration after release.
Surgery was performed using rigid Karl Storz 0° telescope (30 cm
long and 4 mm in diameter) or microscope. Near-total removals of
intracerebral hematomas, 37 hypertensive and 3 traumatic, was done
using this retractor without any complication
