Among the anomalies of intracranial arteries, fenestrations are not uncommon and they may be associated with aneurysms and arterio-venous malformations. The VA is one of the most frequent locations for fenestrations, being more common in extracranial that in intracranial segment and due to different embryological mechanisms. Moreover, among the cerebellar arteries, the posterior-inferior cerebellar artery (PICA) demonstrates the greatest anatomical variability regarding its origin, course, and branching pattern. In some cases, the differentiation between fenestrations and duplications is quite subtle.Methods: We are presenting the case of an association of anomalies with a huge fenestration of the V4 VA and PICA originating from one of the limbs of the fenestration. This was an incidental finding during a computed tomography angiography (CTA) performed because of sudden headache. The anatomical and embryological features of this finding are discussed in detail.Conclusions: The reported anomaly may have different names (fenestration vs duplication) and different embryological origins among the persisting primitive anastomoses pertaining to the lateral spinal artery or posterior spinal artery systems.","PeriodicalId":49461,"journal":{"name":"Surgical and Radiologic Anatomy","volume":"47 1","pages":"136"},"PeriodicalIF":1.4,"publicationDate":"2025-04-30","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"144042083","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":4,"RegionCategory":"医学","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

Its absence is known to be inherited, yet the precise mode of genetic transmission remains uncertain. This study aimed to determine the prevalence of this muscle's absence in a sample of randomly selected families across several generations (parents and their biological children) and to assess the pattern of inheritance related to the presence or absence of the muscle.Methods: A total of 82 individuals (39 males and 43 females) from 20 families, consisting of fathers, mothers, and all their joint offspring, were examined. The presence of the muscle was assessed bilaterally using Schaeffer's test along with additional clinical maneuvers. Descriptive statistical methods, including absolute and relative frequencies, were applied, and results were presented in both graphical and tabular formats.Results: Analysis revealed that the palmaris longus muscle was absent in a greater proportion of individuals (59.75%) than it was present (40.25%). In 80% of the families (16 out of 20), at least one child exhibited the same trait as a parent, indicating a consistent transmission pattern across generations. However, in 20% of families (4 out of 20), the trait skipped a generation.Conclusion: Findings suggest that the absence of the palmaris longus muscle is a hereditary trait, occurring more frequently than its presence, within the studied families. The inheritance pattern aligns with an autosomal dominant transmission model. The absence of the palmaris longus muscle is likely influenced by a dominant gene exhibiting incomplete penetrance and variable expressivity, or potentially by mutational effects.","PeriodicalId":49461,"journal":{"name":"Surgical and Radiologic Anatomy","volume":"47 1","pages":"131"},"PeriodicalIF":1.4,"publicationDate":"2025-04-28","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"144056447","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":4,"RegionCategory":"医学","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

MRA was performed using a standard 3-dimensional time-of-flight technique.Results: MRI showed sulcal hyperintensity in the bilateral occipito-parietal regions on a fluid-attenuated inversion recovery (FLAIR) sequence, suggesting meningitis. MRA revealed no pathological lesions; however, fenestration of the right PCA at the P1-P2 junction and duplications of the bilateral SCAs were incidentally observed.Conclusion: Using MRA, we diagnosed the first case of right PCA fenestration coexisting with bilateral SCA duplication. Although its clinical significance is limited, there may be a risk of misinterpretation or diagnostic confusion with pathological conditions such as aneurysms or dissections. Therefore, accurate identification of these arterial variations during MRA interpretation is essential. Careful observation of MRA images, along with the creation of partial volume-rendering images, is useful and important for diagnosing rare arterial variations.","PeriodicalId":49461,"journal":{"name":"Surgical and Radiologic Anatomy","volume":"47 1","pages":"128"},"PeriodicalIF":1.4,"publicationDate":"2025-04-24","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"144042115","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":4,"RegionCategory":"医学","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

The superior transverse scapular ligament (STSL) was evaluated for dimensions, ossification, and impact on SN morphology. Configurations of the nerve and vessels were categorized, and vascular injury risk was stratified as low, moderate, or high.Results: The SSN passed beneath the STSL in 99% of shoulders, while the SSA and SSV configurations varied. Low vascular injury risk was identified in 82% of shoulders, moderate risk in 10.6%, and high risk in 7.4%, with female cadavers demonstrating higher risk anatomy (13.3%) compared to males (2.0%). Ossified STSLs were significantly associated with smaller SN dimensions, including reduced height and width (p < 0.001).Conclusion: Anatomical variations at the SN play a critical role in determining the risk of vascular injury during SSN release. Surgeons should consider these morphological differences, particularly in cases involving ossified STSLs or higher-risk configurations, to optimize surgical planning.

There are 3 different morphologies: C-shaped, L-shaped and with a \"double angle\". We hypothesis that the distribution of the acromial opening angle in a population was Gaussian and was not influenced by the shape of the angulus acromialis.Methods: Based on 103 dry cadaveric scapulas were determined the angle AÔB as: The crossing point between the spine of the scapula and the medial edge of the scapula (point A), The tip of the angulus acromialis (point O), the lateral edge of the acromion (point B). The shape of the angulus acromialis were noted.Results: The series consisted of 62 (60%) left scapulas and 41 (40%) right scapulas. The shape of the angulus acromialis was: L shape: 47 (45.6%), C shape: 51 (49.5%), and double angle shape: 5 (4.8%). The average angulus acromialis was 105° (87.8°-124.9°; +/- 7.1°). The acromial opening angle as a function of the L, C and \"double angle\" shape was respectively 104.2° (87.8°-119.8°; +/- 7.3°), 105.7° (89.8°-124.9°; +/- 6.9°), 106.1° (98°-116.7°; +/- 8.6°). There was no significant difference in angulus acromialis as a function of side (p = 0.95) or acromion shape (p = 0.54).Conclusion: The average angulus acromialis is 104.9°. Variations in this angle modify the lateral offset of the acromion on plain radiographs, while the width of the acromion remains unchanged. It also modifies the posterior portal for shoulder arthroscopy.","PeriodicalId":49461,"journal":{"name":"Surgical and Radiologic Anatomy","volume":"47 1","pages":"123"},"PeriodicalIF":1.4,"publicationDate":"2025-04-21","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"144051639","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":4,"RegionCategory":"医学","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}
