AI Article Synopsis
- The study aimed to assess how accurately ultrasonography (US) and magnetic resonance imaging (MRI) identify issues in the midline structures of the fetal brain.
- Thirty-two fetuses were examined with both US and MRI, and results were compared with outcomes after birth or autopsy.
- The findings revealed that while US had a high accuracy rate of 93.8%, MRI proved to be more accurate at 100%, highlighting the importance of using both imaging methods in prenatal diagnostics.
Article Abstract
Objective: To evaluate the accuracy of ultrasonography (US) and magnetic resonance imaging (MRI) in midline structures of fetal brain.
Methods: Thirty-two fetuses underwent US and MRI examinatiom. Imagings acquired from US and MRI were analysed, the results were compared with the final outcomes which were obtained after fetal birth or pathological study after induction of labor.
Results: There were 20 cases found abnormal in prenatal CNS ultrasonography (18 cases involving midline structures ). Among these 20 cases, 12 cases were normal in MRI and the fetuses were born in full-term without special problem, 8 cases were abnormal in MRI and fetal autopsy confirmed their abnormalities. Diagnostic accuracy rate of US was 93.8%, sensitivity was 100%, specificity was 87.5%, positive predictive value was 88.9%, negatvie predictive value was 100%. Diagnostic accuracy rate of MRI was 100%, modifying the US results in 4 cases.
Conclusion: US and MRI examinations are important in fetal central nervous system. US could be the first line examination, and MRI is an important supplement because of the high diagnostic accuracy, especially in the image study of midline structures of fetal brain.

The fibroblastic sleeve is a structure potentially enveloping any intravascular device. At ultrasound scan, it typically presents as a thin layer of variably echogenic material covering the catheter surface, which usually tends to remain into the vessel after the catheter removal. However, several case reports have documented its migration toward the heart or pulmonary artery after a central venous catheter removal.

Background: There is little information about when and how cavernosal sinusoidal endothelia develop in the external genitalia of fetuses.
Methods: We examined histological sections of erectile tissue in 37 human fetuses (25 males and 12 females) whose gestational age (GA) ranged from 8 to 40 weeks.
Results: The sinusoidal lumen was filled with blood in the glans of the penis and clitoris at a GA of 10 to 11 weeks, and in the corpus spongiosum at a GA of 15 to 16 weeks.
The CSF p-tau/β-amyloid 42 ratio correlates with brain structure and fibrillary β-amyloid deposition in cognitively unimpaired individuals at the earliest stages of pre-clinical Alzheimer's disease.

CSF concentrations of β-amyloid 42 (Aβ42) and phosphorylated tau (p-tau) are well-established biomarkers of Alzheimer's disease and have been studied in relation to several neuropathological features both in patients and in cognitively unimpaired individuals. The CSF p-tau/Aβ42 ratio, a biomarker combining information from both pathophysiological processes, has emerged as a promising tool for monitoring disease progression, even at pre-clinical stages. Here, we studied the association between the CSF p-tau/Aβ42 ratio with downstream markers of pre-clinical Alzheimer's disease progression including brain structure, glucose metabolism, fibrillary Aβ deposition and cognitive performance in 234 cognitively unimpaired individuals, who underwent cognitive testing, a lumbar puncture, MRI, 18F-fluorodeoxyglucose and 18F-flutemetamol PET scanning.

Background: Giant prolactinoma (size > 4 cm) is a rare condition and accounts for less than 1% of pituitary adenomas. In even rarer cases, these lesions may involve craniocervical structures requiring surgical intervention. The present case is the largest reported giant prolactinoma (99 × 72 × 57 mm).
