Tremor caused by Dandy-Walker syndrome concomitant with syringomyelia: A case report and literature review.
Dandy-Walker Syndrome (DWS) is a rare congenital brain malformation characterized by underdevelopment of cerebellar vermis and cystic enlargement of the fourth ventricle and enlargement of the posterior fossa. The cooccurrence of DWS and syringomyelia in adults is very rare. ⋯ Tremor can be a clinical manifestation in patients of DWS concomitant with syringomyelia in adults. Spinal cord ostomy combined with posterior fossa decompression may be an effective approach for alleviation of symptoms and syringomyelia.

Pineal lesions are common causes of dorsal midbrain syndrome and typically require surgical intervention in symptomatic patients. We describe a unique case of spontaneous resolution of dorsal midbrain syndrome resulting from a pineal gland cyst. ⋯ Dorsal midbrain syndrome resulting from a pineal cyst may spontaneously improve even without a significant change in lesion size. This suggests that observation may be an appropriate initial management strategy.

This is a surgical video that sheds light on the utility of a new imaging modality GLOW800 (Leica Microsystems, Wetzlar, Germany) in resection of vascular tumors. We describe the surgical resection of posterior fossa hemangioblastoma in 2 different patients after informed consent was obtained. ⋯ In addition, it helped in the confirmation of complete resection of the lesion. Another advantage of GLOW800 was that it allowed safe resection of the lesion in and around highly eloquent areas with a narrow surgical corridor (Video 1).

Ventriculostomy-related infection with multidrug-negative strains are challenging to treat. We report the use of new antibiotics in such a case. ⋯ We observed than even in the case of mild meningeal inflammation, ceftaroline penetration in CSF, although moderate, enabled efficient bacterial clearance and clinical efficacy, in adjunction to correct ventriculoperitoneal shunt management.

Pituicytoma is a rare neoplasm arising in the sellar region (World Health Organization grade I). Clinically, pituicytomas mimic nonfunctioning pituitary macroadenomas and are occasionally incidentally discovered at autopsy. Pituitary adenomas can occur with other sellar pathologies, and the term "collision sellar lesions" has been coined for this rare entity. There have only been a few reports of the coexistence of pituicytoma and pituitary adenoma. We present 2 cases of pituicytoma coexisting with acromegaly and Cushing disease. ⋯ Only 117 cases of pituicytoma have been reported since it was first described in 1955. Before our report, only 5 cases of patients with pituicytoma coexisting with pituitary adenoma had been described. The coexistence of these 2 entities may not just be a mere coincidence but may be due to a yet unknown pathophysiologic link or common progenitor lineage of both lesions. Association between pituicytoma and pituitary adenoma is increasingly being reported.
