Several types of soft tissue masses occur in the lower extremities. A mass associated with blood vessels is often difficult to diagnose. A 15-year-old male patient visited the author’s hospital with discomfort and edema in his right calf that had persisted for six months. A physical examination showed no palpable mass other than mild edema. Three masses were found during the ultrasound scan along the small saphenous vein. The masses had a cyst-like appearance and were filled with thrombus. In duplex ultrasound, vascular reflux was represented inside the masses. During surgery, it was suspected that vascular deformation occurred in the small saphenous vein, and simple ligation and resection treatments were performed. The patient was finally diagnosed with venous aneurysms accompanied by thrombosis based on the histology tests. The symptoms disappeared after surgery, and there were no recurrences or unusual findings at the follow-up one year later. Venous aneurysms occurring in the superficial veins of the lower extremities are rarely reported, but treat- ment and diagnosis are important. This paper reports a case of an aneurysm on the small saphenous vein.

In South Korea, the percentage of buildings aged 30 years or older has increased from 37.1% in 2018 to 41.0% in 2022. As of 2022, 54.3% of buildings in Seoul were aged buildings, exceeding half of the total. As the need to secure the stability and maintenance of these aged buildings grows, the Ministry of Land, Infrastructure and Transport inspects existing buildings. It establishes and performs a Facility Management System (FMS) and Building Life History Management System. On the other hand, the current inspection method relies on visual examinations and simple measuring instruments. In addition, different inspection agencies (inspectors) are designated in each inspection cycle. Nevertheless, there are challenges, such as different detailed inspection criteria of inspection agencies, inspection data omissions, and practical limitations to transmitting inspection information to subsequent inspection agencies. As a result, it is difficult to secure and manage consistent inspection information. This study assessed building inspection cases to propose standards for establishing and applying BIM data, focusing on information accumulation and continuity and transferring information efficiently to subsequent inspection agencies, as well as to understand the efficiency of BIM application to building inspection systems. Follow-up research will be needed on the appropriateness of detailed levels, information input and transmission system, and interaction with the national information system by applying BIM to actual building inspections based on these results.

Secondary piriformis syndrome may develop under several conditions. We report on the method and usefulness of arthroscopic treatment of the piriformis muscle and benign perineural cyst of the sciatic nerve. Arthroscopic assessment was performed to a perineural cyst on the sciatic nerve seen through EMG and hip MRI. Through the posterior and posteroinferior portal, the lesion below the piriformis muscle was confirmed following release of the tendon. The incision and drainage of the perineural cyst was done so as to achieve decompression. The excision of the lesion was not carried out so as to avoid injury to the sciatic nerve. Symptoms did not recur during 10 months of follow up appointments. 이차성 이상근 증후군을 유발하는 원인들은 다양하다. 저자들은 이상근 및 좌골 신경 주위의 양성 낭종에 적용할 수 있는 관절 경적 치료의 수술 방법 및 효과에 대하여 보고하고자 한다. 근전도 검사 및 고관절 MRI 검사에서 좌골 신경의 주막 낭종이 관찰 된 증례에 대하여 관절경적 접근을 시행하였다. 후방 및 후하방의 관절경 삽입구를 통하여 이상근 건 유리술 후 이상근 아래 위 치한 좌골 신경에서 병변을 확인하고 절개 및 배액술을 시행하였다. 좌골 신경 손상을 피하기 위해 주막 낭종을 절제하지 않고, 절개 및 감압술 만을 시행하였다. 술 후 10개월 단기 추시에서 증상 재발은 관찰되지 않았다.
