Case ReportsUncommon lesions in the internal auditory canal (IAC): review of the literature and case report.
Despite the relatively frequent occurrence of multiple primary tumors, namely, 10% of intracranial tumors, metastasis is a rare occurrence within the internal auditory canal (IAC) and cerebellopontine angle (CPA). Intracanalicular metastases of adenocarcinoma are documented, but a primary adenocarcinoma remains unreported. We provide a review of uncommon lesions in the IAC and describe to our knowledge the first instance of a primary adenocarcinoma. ⋯ The differentiation between benign and malign lesions in the CPA and IAC is important, as it requires diverse treatment protocols. For the physician this differentiation represents a clinical and radiological challenge. For the developmental research the left-right asymmetry might be a field of research.

Case ReportsA reminder for a very rare entity: massive tongue swelling after posterior fossa surgery.
The purpose of this study is to report a case of presumably neurogenic macroglossia that occurred after surgical trapping of a vertebral artery (VA)-posteroinferior cerebellar artery aneurysm, and to analyze its potential pathogenesis. ⋯ Macroglossia is a rare complication following neurosurgical procedures with very few cases reported so far. It has been attributed to the sitting position and venous flow congestion. We illustrate a case of macroglossia, which occurred following surgery in the prone position. Its etiology remains speculative, but a neurogenic explanation seems most plausible.
