Case ReportsMinimally invasive excision of lumbar epidural lipomatosis using a spinal endoscope.
In this report, we describe the case of a patient with a long-term radiculopathy due to epidural lipomatosis at the L3-4 intervertebral disc level. The fatty tissue was located on the dorsal side of the dural sac in the spinal canal and compressed the dural sac. ⋯ After surgery, the symptoms disappeared, and neurological deficits normalized. We would like to state that epidural lipomatosis is a good candidate for minimally invasive endoscopic surgery because of its anatomic location.

Microsurgical management of lateral ventricular meningiomas: a report of 51 cases.
Lateral ventricular meningiomas are notably rare and the optimal surgical management for them remains a challenge. We made a retrospective study of patients with these lesions and analyzed the clinical findings, radiological features and especially the surgical treatment on the basis of surgical approaches and techniques. ⋯ Understanding the features of lateral ventricular meningiomas will help one to select an appropriate surgical approach. An individualized approach is needed, and the transcortical parieto-occipital approach or transtemporal approach is advantageous for most cases in our opinion. Also, it is possible to achieve a good surgical outcome with little neurological morbidity if we take wise strategies and techniques during excision.

Endoscopic resection of colloid cysts: indications, technique, and results during a 13-year period.
Questions of recurrence and inadequacy of follow-up length persist regarding endoscopic treatment of colloid cysts. In this retrospective review, we report our long-term follow-up during a 13-year period in 35 patients who underwent endoscopic resection of colloid cysts. ⋯ Our series represents the longest follow-up (mean of 7.8 years) of colloid cysts after endoscopic resection. We now use this technique as the first line of treatment for colloid cysts. The risk of recurrence is minimal with gross total resection and/or coagulation of the cyst wall.

Transmuscular trocar technique - minimal access spine surgery for far lateral lumbar disc herniations.
Minimal access spine surgery (MASS) is gaining increasing importance in microsurgery of the lumbar spine. From a current prospective series we present data on MASS for far lateral lumbar disc herniations (LLDH) via a transmuscular trocar technique (T(2)). The surgical procedure and operative results are demonstrated in detail. In contrast to conventional percutaneous endoscopic techniques, T(2) allows one to operate in the typical microsurgical fashion combined with the advantages of a minimal endoscopic approach with three-dimensional visualization of the surgical target using the operating microscope. ⋯ The T(2) technique represents an auspicious alternative to standard open microsurgery for LLDH, which allows achievement of excellent clinical and cosmetic results, preservation of segmental spine stability, and avoidance of excessive soft tissue trauma.

Historical ArticleConcept and treatment of hydrocephalus in the Greco-Roman and early Arabic medicine.
In the ancient medical literature hydrocephalus was not often described although its existence and symptomatology were well known. Most detailed descriptions of hydrocephalus including the surgical treatment are extant in the encyclopaedic works on medicine of the physicians Oreibasios and Aetios from Amida from the 4th and 6th centuries AD, respectively. Because of their broad scientific interests, this type of physicians, typical for the late Roman empire, were known as philosophy-physicians (iota alpha tau rho o sigma o phi iota sigma tau alpha iota). ⋯ Avicenna separated the traumatic haematomas outside the skull from the term hydrocephalus. However Avicenna, as all previous authors, had not linked hydrocephalus with the ventricular system. The autopsy of a child with an exorbitant hydrocephalus performed by the anatomist Vesalius in the 16th century revealed as a single pathology an extremely dilative ventricular system filled with water-like fluid which made it necessary to change completely the ancient concept of hydrocephalus.
