Aims: Determine if early CT evaluation is justified in patients operated on for benign brain tumors.
Background: Researchers have recently questioned the common practice of referring all patients after cranial surgery for CT scans to rule out silent complications.
Methods: The cohort included 257 consecutive patients who underwent surgical removal of a benign brain tumor in the years 2011-2016. The neuroradiology scans performed before and after surgery were reviewed. The postoperative findings considered significant were hemorrhage in ≥50% of the tumor bed, ischemic changes, worsening brain edema, and mass effect. The relationship of the CT findings with the neurological outcome and their effect on the clinical management were evaluated.
Results: No significant complications were found by CT in 247 patients (96%). In the remaining 10 patients (4%), CT showed increased brain edema in 5 and hemorrhage in 5. The clinical management was influenced by the CT findings in 6/10 patients. One had a temporary neurological deficit. None died or required a second operation.
Conclusions: Elective patients operated on uneventfully for benign brain tumors rarely benefit from routine CT after surgery. In most cases, CT follow-up can be replaced by careful neurological monitoring. Exceptions to this rule may be based on clinical judgment and local resources.

Introduction: Residual dizziness (RD) is common in patients with benign paroxysmal positional vertigo (BPPV) after successful canalith repositioning procedures. This study aimed to investigate the therapeutic effects of vestibular rehabilitation (VR) on BPPV patients experiencing RD, and to explore the impact of VR on functional connectivity (FC), specifically focusing on the bilateral parietal operculum (OP) cortex.
Methods: Seventy patients with RD were randomly assigned to either a four-week VR group or a control group that received no treatment.
Non-Hodgkin Lymphoma of the External Auditory Canal: A Rare Primary Involvement.

The authors describe a rare case of non-Hodgkin lymphoma (NHL) with primary involvement of the external auditory canal (EAC) and subsequent dissemination to the central nervous system, initially manifesting as a benign ear infection. This case highlights the importance of considering differential diagnoses in patients with persistent or worsening symptoms unresponsive to empirical treatment. A 53-year-old man presented with a one-week history of aural fullness, otalgia, and otorrhea in the left ear.

Atrial myxoma is a rare benign tumor that can cause a variety of complications, including cerebral infarction. We present a case of a 52-year-old female patient who developed cerebral infarction caused by an atrial myxoma. The patient underwent successful surgical resection of the tumor, and the infarction was managed accordingly.

Cardiac myxomas, the most common primary cardiac tumors, are believed to originate from multipotent mesenchymal cells. Approximately 75% of myxomas occur within the left atrium, increasing the risk of systemic thromboembolic events. While typically benign, atrial myxomas can rarely metastasize to the brain, with fewer than 60 cases reported.

Febrile seizures (FSs) are the most common pediatric neurological disorder, affecting approximately 5 % of children aged 6 months to 5 years. While most FSs are self-limiting and benign, about 20-30 % present as complex FSs (CFSs), which pose a risk of acute brain injury and the development of temporal lobe epilepsy. Various factors, including age, geographical distribution, and type of infection influence the occurrence of FS.
