Case Reports
Endodermal cyst with a non- enhancing nodule in the quadrigeminal cistern developed in an octogenarian.
Intracranial endodermal cysts are congenital lesions that generally develop in the cerebellopontine angle and ventral brainstem of the posterior fossa, whereas endodermal cysts in the quadrigeminal cistern are very rare. We report a rare case of an endodermal cyst in the quadrigeminal cistern with a non-enhancing nodule that developed in patient over 80 years of age. ⋯ This is a rare case of an intracranial endodermal cyst in terms of location and age of onset compared with previous reports. This case demonstrates that endodermal cysts should be considered as a differential diagnosis for lesions in the quadrigeminal cistern with high protein concentration in the cyst and nodule representing chronic inflammation, regardless of enhancing effects.

Comparative Study
Efficacy of Postural Reduction of Vertebral Compression Fracture with Extension Lateral Radiograph Prior to Vertebroplasty.
This retrospective comparative study aimed to evaluate the efficacy of postural reduction of vertebral compression fracture (VCF) using the hyperextension posture before vertebroplasty (VP). ⋯ Hyperextension postural reduction showed superior ABH improvement. It also showed higher ABH at the final follow-up when performed on patients with preoperative ABH ≤15 mm. Although routine hyperextension postural reduction should be carefully approached, postural reduction using supine extension lateral radiography would provide more effective vertebral body height restoration in patients with moderate collapse of vertebral compression fracture with ABH ≤15 mm.

Visual status is routinely evaluated by neuro-ophthalmologic examination and computerized visual field (VF) tests in patients with chiasmal compression secondary to pituitary macroadenoma. Currently, no relevant data exists to accurately quantify the extent of optic apparatus compromise to further guide clinical decision-making. We aimed to assess for a possible quantitative correlation between optic chiasm geometric properties on magnetic resonance imaging (MRI) and VF deficits. ⋯ The strong correlation demonstrated by our results of this relatively simple radiologic measurement with VF status, despite the relatively small cohort, calls for further investigation in this promising direction, and may facilitate with basic assessment and clinical decision-making for patients with equivocal neuro-ophthalmologic evaluation, as well as with poor compliance.

Schwannoma originating from the oculomotor nerve has been reported. However, meningioma originating from this nerve was unknown. ⋯ In such a case, tumor resection after GKS should be considered.

Fibrous dysplasia (FD) is a benign, slowly progressive disease resulting from the replacement of normal bone by fibro-osseous tissue. The incidence of craniofacial involvement of FD is as high as 23%. Sinonasal involvement of FD may lead to obstruction of the natural sinus ostium, resulting in acute sinusitis. We present a rare case of sinonasal FD complicated by subperiosteal abscess that was removed by bicoronal incision and frontal-basal approach in the second surgery. ⋯ After the acute phase, radical excision with reconstruction or debulking surgery after skeletal maturation may prevent recurrence. Although malignant transformation is rare, long-term follow-up is necessary for FD.
