Due to the relatively short time and faster pace of completion of development, minor absent/persistent segments may give rise to either asymptomatic anatomical variants or hemodynamically significant changes. Intracranial vessels - both anterior carotid and posterior vertebrobasilar systems - are known to have many common anatomical variations like hypoplastic segments (A1 or P1 segments of anterior or posterior cerebral arteries) and persistent carotid-vertebrobasilar anastomotic channels. These variants may be displayed using MRI and MRA which represent useful non-invasive investigative modality of the neck and Willis's circle. We report an interesting hitherto rarely reported anatomical variation in the form of spiral twisting of distal vertebral (V4 segments) and vertebrobasilar junction in a 36-year-old female and discuss the underlying embryological possibilities based on the embryological development of the vertebrobasilar system.","PeriodicalId":49461,"journal":{"name":"Surgical and Radiologic Anatomy","volume":"47 1","pages":"97"},"PeriodicalIF":1.4,"publicationDate":"2025-03-11","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"143606964","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}

This report describes a case of the large venous ring around the mandibular condyle found in the cadaver. The left maxillofacial region of a latex-injected embalmed male cadaver (82 years of age at death) was dissected. The large two maxillary veins ran lateral to the capsule and superior to the mandibular notch and coursed posteroinferiorly to merge, and one trunk was formed at the posterior border of the ramus. It then received the superficial temporal vein superiorly to form the retromandibular vein (RMV). In addition, three maxillary veins were drained from the pterygoid venous plexus (PVP), medial to the ramus, one maxillary vein drained from the PVP into the RMV trunk, while two maxillary veins drained from the PVP into the anterior division of the RMV. All five large veins lateral and medial to the condyle drained from the PVP into the RMV. The knowledge of such an anatomical variation might prevent intraoperative bleeding in the temporomandibular joint region.","PeriodicalId":49461,"journal":{"name":"Surgical and Radiologic Anatomy","volume":"47 1","pages":"95"},"PeriodicalIF":1.4,"publicationDate":"2025-03-11","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"https://www.ncbi.nlm.nih.gov/pmc/articles/PMC11897104/pdf/","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"143606890","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":4,"RegionCategory":"医学","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"OA","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

We present an unreported variant where the sartorius muscle was innervated by an accessory branch arising from the ilioinguinal nerve in addition to the proper two branches from the femoral nerve. The iliohypogastric nerve was fused with the ilioinguinal nerve. More proximally, the lumbar plexus also showed unusual arrangement. The anterior branch of the lateral femoral cutaneous nerve arose from the femoral branch of the genitofemoral nerve while the posterior branch arose directly from the second lumbar nerve. The genital branch of the genitofemoral nerve pierced the psoas major muscle more distally than usual, and featured a close proximity with the femoral nerve. Possible variable appearance of these nerves should be kept in mind during several surgical and diagnostic procedures since their iatrogenic or traumatic damage, or their susceptibility to entrapment, pose unpredictable clinical consequences.","PeriodicalId":49461,"journal":{"name":"Surgical and Radiologic Anatomy","volume":"47 1","pages":"90"},"PeriodicalIF":1.4,"publicationDate":"2025-03-11","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"143606965","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: MRA showed no dural arteriovenous fistula; however, there was a stenotic lesion in the precavernous segment of the left internal carotid artery (ICA). This lesion was not considered to be the cause of her symptoms. In addition, the left PCA arose from the basilar artery and the left ICA. There was a small connecting artery between these two PCAs at their proximal segments. These two PCAs fused distally and formed a single PCA. Thus, there was a large arterial ring. Partial maximum intensity projection (MIP) images showed that the left anterior choroidal artery (AChA) appeared normal. Thus, we concluded that there was no hyperplastic AChA, and there was abnormal fusion between the long P1 segment of the PCA and the long PCoA.Conclusion: We diagnosed the first case of abnormal fusion between the long P1 segment of the PCA and the long PCoA.

MRA was performed using a standard 3-dimensional time-of-flight technique.Results: MRA of the intracranial region revealed no pathological lesions. However, a large artery arose from the ophthalmic segment of the right ICA, took an anteromedial course and after making a hairpin turn, continued to the bilateral A2 segments of the ACA. Bilateral A1 segments of the ACA were absent. MRA source images and oblique sagittal reformatted images showed that the anomalous artery was running inferior to the right optic nerve, indicative of carotid-ACA anastomosis or an infraoptic course of the ACA. As some patients have an ipsilateral normal A1 segment, the latter name seems to be inadequate.Conclusion: We encountered a case of right carotid-ACA anastomosis in which the proximal segment had a unique course, ran anteromedially, and made a hairpin turn. This type has not been reported in the relevant English-language literature. Usually, this variation takes a medial course and ascends between the bilateral optic nerves.

Due to its anatomical variability, precise localization is essential for effective nerve blocks and minimizing iatrogenic injury. This study evaluates the feasibility of two distal ultrasound-guided approaches for selective IPBSN blocks, with the aim of addressing the limitations of proximal techniques.Methods: Anatomical layer-by-layer dissections of two paired lower limbs and transverse cross-sections of a third limb were used to map the IPBSN's course and its relationship to the sartorius muscle. Based on these findings, two distal ultrasound-guided approaches were tested: a proximal medial para-patellar approach at the level of the patella's superior aspect and a distal medial para-patellar approach near the medial femoral condyle. Ultrasound-guided injections (0.1-0.3 mL) targeting the IPBSN were performed on four lower limbs, followed by anatomical validation through dissection.Results: The IPBSN was consistently identified as a honeycomb structure within a distinct fascial compartment. Both approaches effectively localized the nerve, with observed diffusion suggesting a potential compartment for selective nerve block. This dual-modality approach of ultrasound imaging and dissection enabled precise IPBSN localization, overcoming topographical variability relative to the sartorius muscle.Conclusion: Distal ultrasound-guided IPBSN blocks show promise for knee pain management by achieving targeted analgesia while preserving muscle function. Further studies are needed to validate these techniques and refine injection protocols for clinical use.","PeriodicalId":49461,"journal":{"name":"Surgical and Radiologic Anatomy","volume":"47 1","pages":"87"},"PeriodicalIF":1.4,"publicationDate":"2025-03-06","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"143568671","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}
