This study was undertaken primarily to investigate the possible prognostic values of several cell-cycle regulators for the prediction of functioning pituitary adenoma (FPA) recurrence after surgical resection by immunohistochemically analyzing tumor samples obtained by surgical resection. ⋯ Our findings indicate that p16, pRB protein, and cyclin D1 are associated with recurrence FPA after surgical resection.

Infection associated with an intracranial meningioma is an extremely rare condition. Only six cases have been described in the literature. Because of its dual pathologies, initial radiologic diagnosis can be difficult. We present the first reported case of multiple infected intracranial meningiomas and correlate the radiologic and histologic findings. ⋯ In the appropriate clinical context, diffusion-weighted imaging and apparent diffusion coefficient map aid the diagnosis of infected intracranial meningiomas.

Plastic clips are made of diamagnetic material and may result in fewer computed tomography (CT) and magnetic resonance artifacts than titanium clips. Considering that polymer plastic clips are increasingly being used in endoscopic surgery, our study examined the CT and magnetic resonance imaging (MRI) characteristics of plastic clips after application in the neurocranium and compared them with titanium clips. ⋯ The plastic clips are made of a diamagnetic, nonconductive material that results in fewer CT and MRI artifacts than titanium clips.
