The thalamus is a deep cerebral structure that is crucial for proper neurological functioning as it transmits signals from nearly all pathways in the body. Insult to the thalamus can, therefore, result in complex syndromes involving sensation, cognition, executive function, fine motor control, emotion, and arousal, to name a few. Specific territories in the thalamus that are supplied by deep cerebral arteries have been shown to correlate with clinical symptoms. The aim of this review is to enhance our understanding of the arterial anatomy of the thalamus and the complications that can arise from lesions to it by considering the functions of known thalamic nuclei supplied by each vascular territory.

Review Case Reports
Transoral protrusion of a Ventriculoperitoneal catheter due to jejunal perforation in an Adult: Rare case report and review of the literature.
Although several complications after ventriculoperitoneal shunting (VPS) have been reported, transoral protrusion of a peritoneal catheter is a rare event. In the few reported cases from the literature, it is more common in pediatric patients. This case report describes the first adult in the literature with a transoral VPS protrusion after jejunal perforation. ⋯ We present a rare case of transoral protrusion of a peritoneal catheter 11 months after a VPS procedure and review of the literature through this article.

To determine use of magnetic resonance imaging (MRI) for management of spinal trauma as a function of the availability of an MRI scanner across AO regions. ⋯ MRI use varies across AO regions, with clinical decision making on obtaining MRI in spinal trauma being influenced heavily by the availability of an MRI scanner.

Nervus intermedius neuralgia is an extremely rare craniofacial neuralgia characterized by paroxysmal episodes of pain located deep in the ear, typically triggered by sensory or mechanical stimuli at the wall of the auditory canal without underlying pathology. Pain is sometimes associated with disorders of lacrimation, salivation, and taste. ⋯ It is important to keep in mind the possibility of nervus intermedius neuralgia in patients who present with intermittent episodes of pain located deep in the ear. Furthermore, 3D-MRC/MRA fusion imaging is useful for decision-making in surgery. Microvascular decompression was highly effective in our case. Based on radiological findings, microvascular decompression should be considered a viable treatment option.

In the presence of a skull deformity after large decompressive craniectomy (DC), neurologic deterioration manifesting as epileptic syndrome (ES) may occur independently of the primary disease or spontaneous improvement may be unduly impaired, and these unfavorable outcomes have sometimes been reversed by cranioplasty. The objective of this study was to analyze the influence of cranioplasty on the presence of ES in patients who underwent DC. ⋯ In routine clinical practice, altered amplitudes were observed in the region of bone defects. Although cranioplasty reduced pathologic EEG status (epileptogenic paroxysms), it was not able to produce new EEG tracings that could predict changes in seizure discharge or reduce ES.
