BACKGROUND: Radiological differentiation between a low and high grade lesion is crucial on deciding the extent of resection and prognostication. Occasionally the imaging features can be confusing between the two. We report such a case which was a radiological dilemma. The lesion appeared apparently benign and extra-axial on routine magnetic resonance (MR) sequences. However, there were subtle clinical and imaging clues towards high grade lesion. CASE DESCRIPTION: A 27-year-old lady presented with multiple cranial nerve palsies, gait ataxia and features of raised intracranial pressure...

Cephalic tetanus is defined as a combination of trismus and paralysis of one or more cranial nerves. Since it is a rare cause of facial nerve palsy, it is often overlooked as a differential diagnosis. We present the case of a 75-year-old man admitted to our emergency department with left facial nerve palsy, left ptosis and dysphagia 2 weeks after a head laceration. Soon after admission, he was orally intubated because of massive aspiration. A delayed diagnosis of cephalic tetanus was reached only when he was extubated and trismus and risus sardonicus were identified in addition to facial nerve palsy...

PURPOSE OF REVIEW: Despite nerve-sparing surgery, postoperative shoulder morbidity remains high and significantly impacts patient's quality of life. This review will focus on recent findings of anatomical nuances of the cranial nerve XI (CN XI) along its course in the neck and possible reasons for postoperative morbidity. RECENT FINDINGS: The most recent studies identified three different branching patterns of the CN XI in the neck. In type 1 (66%), the branch for trapezius muscle exits at the posterior border of the sternocleidomastoid muscle (mSCM)...

This paper describes two patients with squamous cell carcinoma (SCC) of the periocular and periorbital skin who presented with trigeminal neuralgia. Both patients had previous cutaneous SCC of the scalp treated successfully with surgical resection but later presented with neuro-ophthalmic findings suggesting perineural invasion (PNI) of SCC. PNI of SCC in the periocular skin or orbit can lead to devastating effects if malignant cells seed into the orbit and adjacent cranial nerves as our two patients developed an orbital apex syndrome...

REVIEW
Jeong Hyun Lee, Kai-Lung Cheng, Young Jun Choi, Jung Hwan Baek
The neck has intricately connected neural structures, including cervical and brachial plexi, the sympathetic system, lower cranial nerves, and their branches. Except for brachial plexus, there has been little research regarding the normal imaging appearance or corresponding pathologies of neural structures in the neck. The development in imaging techniques with better spatial resolution and signal-to-noise ratio has made it possible to see many tiny nerves to predict complications related to image-guided procedures and to better assess treatment response, especially in the management of oncology patients...

The extinct North American lion (Panthera atrox) is one of the largest felids (Mammalia, Carnivora) to have ever lived, and it is known from a plethora of incredibly well-preserved remains. Despite this abundance of material, there has been little research into its endocranial anatomy. CT scans of a skull of P. atrox from the Pleistocene La Brea Tar pits were used to generate the first virtual endocranium for this species and to elucidate previously unknown details of its brain size and gross structure, cranial nerves, and inner-ear morphology...

A 61-year-old female presented with 4 years history of left-sided hemifacial spasm. Head MRI and angiography indicated left vertebral artery dissecting aneurysm which compressed ipsilateral cranial nerves Ⅶ and Ⅷ. Microvascular decompression was performed. The dissecting aneurysm was pushed apart and the distal part of the parent artery was adhered to the dura on the petrosum. The compressed nerves were totally decompressed. The symptom of facial spasm was completely resolved immediately after surgery and did not recur during 6 months of follow up...

Pituitary metastases (PMs) are uncommon, representing only 1% of pituitary lesions. The diagnosis of PMs can be challenging and an optimal management remains to be determined. Here, we present a pilot clinical study on the efficacy and safety of hypofractionated stereotactic radiosurgery (SRS) with an optimized dosimetric plan in treating PMs. Between June 2013 and December 2014, seven consecutive patients (4 men and 3 women; median age 62 years) had been diagnosed with PMs based on their characteristic clinical and radiological features and subsequently treated using hypofractionated SRS...

A 72-year-old man with ulcerative colitis (UC) presented with complete left abducens nerve palsy. Although MRI showed no significant changes, cerebrospinal fluid analysis revealed pleocytosis and elevated protein and interleukin (IL)-6 levels. His serum proteinase 3-antineutrophil cytoplasmic antibody (PR3-ANCA) level was also elevated to 31.1 U/mL, but granulomatosis with polyangiitis was not observed. On the basis of the diagnosis of autoimmune cranial neuropathy, he was treated with steroid therapy. While tapering steroid therapy, his serum PR3-ANCA levels; cerebrospinal fluid findings, including IL-6 levels; and symptoms improved...

Anomalies in the frontal lobe can interfere with visual function by compression of the optic chiasm and nerve. The gyrus rectus is located at the anterior cranial fossa floor superior to the intracranial optic nerves and chiasm. Compression of these structures by the gyrus rectus is often caused by neoplastic or dysplastic growth in the area. We report a rare case of a herniated gyrus rectus impinged on the optic chiasm and nerve without a clear pathological cause for the herniation.

BACKGROUND: A pneumocele occurs when an aerated cranial cavity pathologically expands; a pneumatocele occurs when air extends from an aerated cavity into adjacent soft tissues forming a secondary cavity. Both pathologies are extremely rare with relation to the mastoid. This paper describes a case of a mastoid pneumocele that caused hypoglossal nerve palsy and an intracranial pneumatocele. CASE REPORT: A 46-year-old man presented, following minor head trauma, with hypoglossal nerve palsy secondary to a fracture through the hypoglossal canal...
