Only limited attention has been paid to the anatomy and clinical importance of the falcine venous plexus. The aim of this study was to evaluate the falcine venous plexus anatomically using scanning electron microscopy (SEM), and to provide guidance for neurosurgical approaches. Latex or ink was injected into the superior and inferior sagittal sinus. The(More)
Anatomical and surgical textbooks give almost no attention to the intradural communications between dorsal rootlets of adjacent spinal nerves. These communications can be of significance in various neurosurgical procedures and clinical conditions of the region. The spinal cord of six formaldehyde-fixed cadavers was dissected from C1–S5. The dorsal rootlets(More)
BACKGROUND A neurosurgical laboratory training model is designed for trainees in microneurosurgery to learn to handle surgical microscopes and microneurosurgical instruments. The silicone injection of a fresh cadaveric cow cranium is an alternative to using a cadaveric human brain for becoming familiar with the cerebellopontine angle (CPA) via the(More)
It is widely believed that the main function of denticulate ligaments (DLs) is to stabilize the spinal cord within the vertebral canal. The aim of this study was to assess the anatomical and histological structure of the DLs and to document any regional differences. Five formalin-fixed adult cadavers were used. The DLs were exposed via the posterior(More)
The posterolateral sulcus (PLS) is an important surgical landmark, especially for DREZ (dorsal root entry zone) operations. The present study aimed to show the variations of the PLS using human spinal cord histological sections and report the variability in the number of dorsal rootlets of the spinal nerves in each the spinal cord segment. Further, measure(More)
Streptococcus constellatus is a microorganism that lives commensally in the oropharyngeal region, urogenital region, and intestinal tract. However, it can cause infection in patients with certain predisposing factors. Rarely, this microorganism can cause a brain abscess. Thalamic localization of brain abscesses is much rarer than abscesses in other(More)
During routine anatomical dissection of the upper extremity of a 64-year-old cadaver for educational purposes, we observed variations in the brachial plexus on each side. On the right an anomaly of cord formation was present and on the left there was a communication between the musculocutaneous nerve (MCN) and median nerve (MN). On the right side the(More)
Background. Primary spinal dural lymphomas (PSDL) are tumors with characteristic histopathology of a lymphoma, which are completely in the spinal epidural space without any other systemic involvement. Extranodal primary lymphoma involving nervous system prefers thalamus/basal ganglia, periventricular region, cerebellum, eyes, meninges/dura, and cranial(More)
Vertebral brown tumors are rare, non-neoplastic bone lesions that occur in the setting of hyperparathyroidism. There are differences in the management of them in the literature. Because brown tumors usually resolve after a parathyroidectomy. We present a case of a thoracic vertebral brown tumor with paraparesis.
The sine-wave-shaped skin incision is a technique that minimizes skin-related complications near burr hole caps after electrode placement for deep-brain stimulation (DBS). Between 2011 and 2013, 54 DBS electrodes were implanted in 27 consecutive patients with Parkinson’s disease (PD), essential tremor, or dystonia. The sine-wave incision was used in 26(More)
