Among several novel predictors on noncontrast computed tomography (CT) for hematoma expansion in spontaneous intracerebral hemorrhage (sICH), shape irregularity grade, satellite sign, and island sign are all related to irregular shape of hematoma. This study is aimed to compare the accuracy of these imaging markers for predicting hematoma expansion in the same cohort of sICH patients. ⋯ Island sign seems to be the optimal shape-related predictor for hematoma expansion in sICH patients and could be included in the future predictive model for hematoma expansion.

Review Case Reports
Pituitary Adenoma and Craniopharyngioma Collision Tumor: Diagnostic, Treatment Considerations and Review of the Literature.
Different diseases may occur within the same anatomic space and invade one another. Lesions of this nature are described as collision tumors. Collision tumors of the sella are rare, with pituitary adenoma-craniopharyngiomas having been described in only 15 cases. We discuss common and rare lesions of the sellar region, their neurodiagnostic qualities, and treatment considerations. ⋯ Many mechanisms for the development of collision lesions have been theorized, and further investigation may provide definitive answers regarding the origin of these neoplastic entities.

Review Case Reports
Recurrent secondary trigeminal neuralgia caused by an obliterated tentorial dural arteriovenous fistula cured with surgical resection: A case report and literature review.
Trigeminal neuralgia (TN) caused by a tentorial dural arteriovenous fistula (TDAVF) is quite rare. To date, only 10 cases and 2 small case series have been reported in this regard, and most were treated with either embolization or surgery. Here, we report a unique case of a TDAVF presented as TN, which was embolized with Onyx first and resected later. ⋯ Even complete obliteration of fistula could cause the recurrence of neuralgia, and resection of embolized dilated veins might be effective for the treatment of TN in such recurrent cases.

Review Case Reports
Meckel's Cave Epidermoid Cyst Presenting as Multiple Cranial Nerve Deficits Due to Indirect Tumoral Compression of the Cavernous Sinus: A Case Report and Literature Review.
Epidermoid cysts in Meckel cave are exceedingly rare. Since 1971, only 17 cases have been reported in the literature, with most patients presenting with trigeminal hypesthesia. However, outgrowth of these lesions from Meckel cave can rarely lead to compression of the proximate cavernous sinus and the neurovascular structures contained within. To date, 2 cases have reported a Meckel cave epidermoid cyst presenting clinically as an intracavernous cranial nerve palsy, presumably a clinical manifestation of cavernous sinus compression from the lesion. ⋯ This is a unique report depicting an epidermoid cyst in the Meckel cave causing numerous cranial nerve deficits because of indirect tumoral compression of cranial nerves within the cavernous sinus.

Extended fusion can be performed in patients with Lenke 5C adolescent idiopathic scoliosis (AIS) with a large and relatively rigid thoracic curve. Progression of the thoracic curve is related to coronal imbalance. We aimed to determine the correlation between the upper instrumented vertebra choice and coronal balance in patients with Lenke 5C AIS. ⋯ In patients with Lenke 5C AIS, thoracic curve fusion results in better correction of the thoracic curve but no improvement in coronal balance. With TL/L fusion, a postoperative UEV tilt >5° leads to better coronal balance.
