Summary: Neurovascular compression syndromes are challenging disorders caused by the compression of cranial nerves. Different types include trigeminal neuralgia, hemifacial spasm, and glossopharyngeal neuralgia. The underlying pathomechanisms are not fully understood, but a systematic review suggests that anatomical and hemodynamical changes alone are insufficient to account for all the symptoms, and additional factors such as nerve-related changes, brain changes, and inflammatory background may play a role.

Summary: We reported a rare case of combined four neurovascular compression syndromes in a 41-year-old woman. The patient presented with left hemifacial spasm, left glossopharyngeal neuralgia, left type-writer tinnitus, and vestibular paroxysmia. Microvascular decompression resolved all the symptoms without recurrence in a one-year follow-up. This case report contributes to the understanding of the development mechanism of combined multiple neurovascular compression syndromes.

Summary: This study aimed to investigate the relationship between neurovascular compression syndrome (NVCS) and unruptured cerebral aneurysms (UCAs). The results showed that the prevalence of UCAs in NVCS patients was significantly higher than in the control group. Most UCAs associated with NVCS were small aneurysms and did not rupture during the course of NVCS treatment.

Summary: The superior cerebellar artery (SCA) plays a crucial role in trigeminal neuralgia, but its anatomical variability can also cause other neurovascular compressions (NVC), including hemifacial spasm and oculomotor nerve palsy. It is also associated with ischemic syndromes and aneurysm development. Understanding the anatomical variability of SCA is important for managing patients with NVCs associated with this artery.

Summary: This study investigated the outcomes of microvascular decompression (MVD) surgery in patients with hemifacial spasm (HFS) who did not show definite neurovascular compression (NVC) on preoperative MRI. The most common vessel compressing the facial nerve was the AICA, and the most common compression site was the cisternal portion of the facial nerve. All patients experienced symptom improvement after the surgery, with only one patient showing recurrence.

Summary: This study evaluated the necessity of postoperative NICU admission after MVD surgery and found that routine admission of patients to NICU does not provide additional value. Only patients with specific indications need to be admitted to NICU. This policy can lead to cost and resource savings.

Summary: Painful tic convulsif (PTC) is more common in middle-aged women between 40 and 60 years old, presenting initially as hemifacial spasm and often affecting the left side. Vertebrobasilar artery compression is the most common single vascular compression cause of PTC. Microvascular decompression effectively treats PTC, with a cure rate of over 80%. Involvement of the anterior inferior cerebellar artery/posterior inferior cerebellar artery predicts successful surgery, while older age is a predictor for recurrence.

Summary: The study aimed to evaluate the comparability between early-phase amyloid PET scans and 18F-FDG PET brain topography at the individual level and their ability to differentiate patients. The results showed that early-phase amyloid PET scans and 18F-FDG PET SUVR had similar performances in diagnosing AD patients, and both were able to effectively distinguish AD patients from healthy controls. The findings demonstrate the cost-saving potential of amyloid PET and support the routine use of this modality for individual classification in clinical practice.

Summary: We present a case of a 74-year-old man who had previously undergone radical prostatectomy for prostatic cancer. Follow-up imaging detected elevated prostate-specific antigen, prompting the use of F-18-prostate-specific membrane antigen (PSMA) ligand PET/CT scan. The scan revealed increased focal uptake in the temporal bone and equivocal external iliac nodes, which were subsequently confirmed to be related to otospongiosis.

Summary: This study aimed to evaluate the performance of PET and CT image fusion for GTV segmentation of head and neck cancers using conventional, deep learning, and output-level voting-based fusions. The results showed that PET/CT information fusion adds significant value to segmentation tasks, outperforming PET and CT-only methods. Both conventional image-level and DL fusions achieved competitive results. Output-level voting-based fusion with majority voting of several algorithms resulted in statistically significant improvements in HNC segmentation.

Summary: Although AI-powered tools may change the way radiologists work, they will not replace them completely. Radiologists have unique advantages in multidisciplinary and patient-centered consulting tasks. To adapt to this trend, training for radiologists should focus on clinical backgrounds, communication skills, and integration with other disciplines.
