Case Reports
Synchronous Diagnosis of Intradiploic Epidermoid Cyst and Anatomically Close Associated Chronic Epidural Hematoma.
Intradiploic epidermoid cyst (IEC) concurrent with chronic epidural hematoma (CEDH) has never been reported in the literature. We report a unique case of IEC concurrent with anatomically close associated CEDH. ⋯ Intradiploic epidermoid cyst concurrent with chronic epidural hematoma is extremely rare. We present the first case of intradiploic epidermoid cyst concurrent with anatomically close associated chronic epidural hematoma.

To compare the efficacy of long and short segment instrumentation after pedicle subtraction osteotomy (PSO) for thoracolumbar kyphosis caused by ankylosing spondylitis (AS). ⋯ Both approaches were able to maintain sustained surgical outcomes. Short segment instrumentation is recommended for AS patients with bridging syndesmophytes. Long constructs are better indicated for patients without fully ossified anterior longitudinal ligaments. Nevertheless, extension of the length of instrumentation might not prevent complications such as proximal junctional kyphosis or rod fracture in patients without fully ossified vertebrae.

Lhermitte-Duclos disease is an extremely rare pathologic entity characterized by a cerebellar mass composed of enlarged cerebellar folia containing abnormal ganglion cells. This entity usually presents in young and middle-aged adults and rarely in children. There is no study in the literature analyzing the long-term clinical course of this disease to assess the behavior primarily because of its rarity. ⋯ LDD is seen rarely and demands a high degree of suspicion in patients presenting with cerebellar mass and/or imaging characteristics. It is prudent to keep these patients in close follow-up for early detection of malignant transformation.

Lumbar disc herniation (LDH) is a common spinal problem, with reoperation rates of 6%-24%. Although different surgical techniques are used for treatment, there is still debate regarding whether fusion techniques can reduce the reoperation rate in patients with LDH. ⋯ Among surgical procedures for LDH, fusion techniques are related to lower reoperation rates compared with discectomy, but at the expense of higher medical costs.

Intraoperative resection or occlusion control is indispensable in the surgery of vascular anomalies. This can be conducted using local vascular imaging modalities or angiographic techniques. This series was performed to assess whether cerebral arteriovenous malformations (AVMs) and dural arteriovenous fistulae (dAVFs) can be detected in a sufficient quality by intraoperative 3-dimensional (3D) fluoroscopy with intravenous contrast application. ⋯ This technique quickly supplies intraoperative images of adequate quality to locate cerebral AVM and dAVF. However, it does not produce dynamic images. Thus, early draining veins cannot be located unless anatomically identified based on the preoperative DSA. In this case, it can be used for intraoperative obliteration control.
