Hyperprolactinemia is a prevalent endocrine disorder presented in patients with non-functional pituitary adenomas (NFPAs). However, the mechanism involved in hyperprolactinemia in NFPA is not fully illustrated. The current study aims to investigate predictors for hyperprolactinemia in NFPA via analyzing relevant clinical features. Thus, in this study, a cohort of 214 cases with integrated medical records was retrospectively analyzed concerning clinical, pathological, and endocrinological studies before and after surgery.Hyperprolactinemia happened in 93 cases (43.5%). Women (adjust odds ratio [OR] = 3.093; P < .01), age of patients (adjust OR = 0.951; P < .01), and serum free tetraiodothyronine (FT4) level (adjust OR = 0.882; P = .02) were independent predictors for developing preoperative hyperprolactinemia. Tumor size and hypopituitarism had no impact on hyperprolactinemia. During a median follow-up of 43.5 (range, 22-80) months, 83.9% patients with preoperative hyperprolactinemia experienced prolactin (PRL) normalization. Preoperative PRL level (adjusted OR = 1.741, P = .03) was the exclusive predictor for PRL normalization after adjusting for tumor volume, preoperative serum FT4 concentration, and postoperative residual. The PRL normalization rate of patients with lower PRL level (

Intraventricular meningiomas are rather rare and only represent a small proportion of all intracranial meningiomas. Data are still limited toward this peculiar entity and surgical resection remains challenging for neurosurgeons. The purpose of present study is to demonstrate clinical features, surgical treatment, and potential risk factors determined long-term prognosis of intraventricular meningiomas. A total of 89 surgically treated and histopathologically confirmed intraventricular meningiomas were identified in our institution from 2008 to 2018. Clinical features, neuroimaging findings, surgical records, and prognosis data were extracted and reviewed retrospectively. Group comparison and recurrence-free survival analysis were performed. Female predominance was well established with a sex radio of 2.1:1. Raised intracranial pressure and decline of visual acuity were 2 chief symptoms that patients generally complained of. Preoperative magnetic resonance imaging (MRI) scans were performed in all patients and there was a trend toward lateral ventricular meningiomas were larger in size than others (P = .07). Superior parietal lobule and temporal approach were widely adopted and lateral/4th ventricular meningiomas were more easily to acquire total tumor resection as compared with 3rd ventricular meningiomas (P = .03). After an average follow-up of 57.3 months, 6 patients experienced recurrence of disease in our series. Individuals with subtotal resection (P

Rationale Aggressive pituitary adenomas and pituitary carcinomas are rare and demand multiple treatment strategies. Temozolomide, an orally active alkylating chemotherapeutic agent, has recently been recommended as a salvage medication for refractory pituitary adenomas or carcinomas. Patient concerns A 17-year-old male presenting with aggressive prolactinoma that continued to progress despite surgery, gamma knife, and dopamine agonists. Diagnoses The diagnosis of refractory aggressive prolactinoma was made on the basis of clinical findings and the lack of efficacy of conventional treatment. Interventions The patient received the most frequently recommended regimen of temozolomide treatment for 22 cycles. Outcomes Temozolomide resulted in a remarkable shrinkage of tumor mass and inhibition of prolactin secretion and this patient's clinical condition improved progressively. Lessons Temozolomide can be used as a salvage treatment to refractory pituitary tumors and o(6)-methylguanine-DNA methyltransferase (MGMT) status is a significant predictor to the effectiveness of temozolomide based on the existing literature.

Rationale:Mental retardation (MR) is a chronic condition that often has no readily identifiable cause or treatment. Aggression and psychiatric symptoms are prevalent in children with MR. Surgical treatment of aggression and psychiatric symptoms of MR is seldom investigated and studies are li

We read with interest the recent NeuroImage presented by Ye et al.1 as an example of calcified otogenic brain abscess. The authors described a patient with a 2-year history of recurrent episodes of purulent discharge from the left ear and an incidental calcified brain mass in the ipsilateral temporal lobe.1 In the largest case series of calcifying pseudoneoplasm of the neuraxis (CAPNON), all …
