Background: Colloid cysts are known to cause neuropsychological impairment. However, the specific domains that affected and their outcomes following excision not studied in past. In current study, we evaluated different involved colloid cyst patients how they fared on long-term follow-up after excision. Methods: A retrospective cohort of sixteen managed a tertiary care center were included study. The clinical presentation, largest diameter, presence ventriculomegaly using Evans index noted an MR brain imaging preoperatively. neurocognitive evaluation was performed by neuropsychologist at presentation 1 month year Results: memory, rate learning, verbal fluency, sustained attention, focused information processing speed, auditory working memory. There clinically meaningful improvement visual memory ( P = 0.054) logical 0.058) operated patients, while other parameters improved slightly. No significant change early late postoperative assessments. Conclusions: Neurocognitive Visual show postsurgical decompression.

The prevalence of female-to-male (FtM) transgender individuals has risen recently, yet the effects cross-sex hormone therapy on volumetric differences in hippocampal subfields remain poorly understood. This study aimed to evaluate gray matter (GM) volume, especially focusing subfields, FtM and premenopausal cisgender women. Seventeen who had undergone hysterectomies were receiving testosterone before participating this study, along with 20 women, underwent a single session T1-weighted magnetic resonance imaging (MRI). group significantly higher free-testosterone (free-T) levels lower estradiol compared women (p < 0.001). In voxel-wise analysis, showed larger GM volumes caudate nucleus, hypothalamus, thalamus 0.01, FWE-corrected). More specifically, right subiculum volume was 0.05, Bonferroni-corrected), these positively correlated free-T (r = 0.34, p 0.04). revealed specific subfield testosterone-treated when group. These findings might help elucidate morphological variation cerebral regions associated contribute our understanding gender-affirming treatments as well.
