Pulmonary nodular lymphoid hyperplasia is a reactive lymphoproliferative disease. It is very rare, which means that many aspects of the disease are unknown or have not been proven. Pulmonary nodular lymphoid hyperplasia can be symptomatic or asymptomatic, progressive or not, and solitary or multiple, and a surgical approach is the current treatment of choice. We present a case of pulmonary nodular lymphoid hyperplasia that was visualized as multiple ground glass opacities on a computed tomography (C T) scan, and observed for 1 year because the patient was pregnant. Over this period, the number and extent of the opacities progressed, but no symptoms were reported. A surgical biopsy was done and some remaining lesions regressed on follow-up CT scans, while others progressed, without any appearance of symptoms.

A 78-year-old man underwent laparoscopy-assisted total gastrectomy for gastric cancer (pT3N0M0). Multiple port sites were used, including a 10 mm port for a videoscope at the umbilical point and three other working ports. During the six-month follow-up evaluation, a 2 cm enhancing mass confined to the muscle layer was found 12 mm from the right lower quadrant port site, suggesting a metastatic or desmoid tumor. Follow-up computed tomography imaging two months later showed that the mass had increased in size to 3.5 cm. We confirmed that there was no intra-abdominal metastasis by diagnostic laparoscopy and then performed a wide resection of the recurrent mass. The histologic findings revealed poorly differentiated adenocarcinoma, suggesting a metastatic mass from the stomach cancer. The postoperative course was uneventful, and the patient completed adjuvant chemotherapy with TS-1 (tegafur, gimeracil, and oteracil potassium). There was no evidence of tumor recurrence during the 50-month follow-up period.

The authors describe the use of a self-expandable stent in a temporary deployment for treatment of a very wide-neck A1 segment of anterior cerebral artery (ACA) aneurysm following incomplete clipping. A 39-year-old hypertensive man presenting with seizure-like movement underwent computed tomography, which showed acute subarachnoid hemorrhage and an A1 segment of ACA aneurysm with superior and inferior projection. He underwent surgical clipping of the aneurysm, but superior and posterior portion of wide-neck aneurysm remained. We decided to treat the remnant aneurysm using an endovascular modality. After selection of the aneurysm, coil packing was performed assisted by the temporary semi-jailing technique. The Enterprise stent (Cordis Neurovascular, Miami, FL, USA) was deployed and recaptured repeatedly for angiography to ensure safety of the small caliber parent artery. Successful semi-deployment and recapture of the stent allowed subtotal coil occlusion of the aneurysm with good anatomic and clinical results. No complications were encountered. The stent could be recaptured up to the point where the proximal end of the stent marker was aligned with distal marker band of the microcatheter, approximately 70% of the stent length. The temporary semi-jailing technique is feasible for wide-neck aneurysm with small caliber parent artery.

A 3-year-old, 5.6 kg, castrated, male, British short hair cat presented with subtle weight-bearing lameness of the right hindlimb when walking suddenly after rest. On physical examination, the patient experienced pain when the right stifle joint was hyperextended. There was no clinical improvement of lameness or pain of the right hindlimb, despite the administration of analgesic drugs for one week. During diagnostic arthroscopy of right stifle, mild synovitis and cranial cruciate ligament (CCL) impingement on osteophyte of the intercondylar notch (ICN) was observed. Computed tomography was applied to determine an accurate surgical plan. Arthroscopy-assisted notchplasty, including removal of the osteophyte, was performed using chisel and arthroscopic burr. At 4 weeks postoperatively, the frequency of subtle weight-bearing lameness of the right hindlimb was significantly reduced. At 6 months postoperatively, the patient exhibited normal ambulation without recurrence of lameness. Impingement of CCL may cause subtle lameness and pain. Arthroscopy can be a good diagnostic tool for early-stage CCL disease. Notchplasty can be recommended for osteophyte-induced CCL disease.

Paratracheal air cysts are a rare entity in which cystic formation occurs adjacent to the trachea. Most patients with paratracheal air cysts are asymptomatic, and the cysts are detected incidentally on chest radiograph or computed tomography (CT) scan. Most symptomatic patients complain of pulmonary symptoms or repeated respiratory infection. Rarely, the air cysts can lead to paralysis of the recurrent laryngeal nerve as a result of direct compression. We report a case of a 59-year-old male patient who presented with voice change, and the cause was identified as paratracheal air cysts on a chest CT scan. Surgical resection via video-assisted mediastinoscopy was performed, and the voice recovered immediately after the operation.

흉막외혈종은 혈흉과 달리 출혈된 혈액이 가슴막공간에 고이지 않고 벽측가슴막과 가슴속근막(endothoracic fascia) 사이에 고이는 질환이다. 이 질환은 흉벽혈관 손상후 벽측가슴막이 손상되지 않아서 혈액이 가슴막 공간으로 나오지 못하여 발생한다. 컴퓨터단층촬영에서 흉벽의 벽측가슴막과 가슴속근막 사이에 있는 지방층이 가슴막 밖에 위치하는 가슴막밖 지방 징후로 진단할 수 있다. 저자들은 외상후 흉막외혈종을 진단하고 비디오흉강경수술로 성공적으로 치료하였기에 문헌고찰과 함께 보고하는 바이다.

우리나라에서 폐흡충증은 1960년대 까지만 해도 매우 흔하여 폐의 공동 병변을 일으키는 주요 감염 원인이었으나 현재는 매우 드문 감염병이 되었다. 16세 남자가 갑자기 열감, 기침, 객혈이 발생하여 가슴 X-선 영상검사를 실시하였고, 공기음영(air bubble)을 포함하고 있는 결절과 간유리 음영으로 세균학적으로 결핵균이 확인되지 않았으나 결핵으로 진단받고 항결핵제로 치료를 받았다. 항결핵제 치료 후에 더 이상 기침 등의 증상은 호소하지 않았으나 가슴 X-선 영상검사와 가슴 컴퓨터단층촬영검사에서 병변이 악화되어 비디오 흉강경 구역절제술을 실시 받았으며 조직검사에서 폐흡충란이 발견되어 폐흡충증으로 진단된 증례를 경험하여 보고하고자 한다.

Background: The purpose of our study was to evaluate the accuracy of reduction based on postoperative computed tomography (CT) images after arthroscopic stabilization using tightrope system for unstable distal clavicle fracture. Methods: Twelve patients with distal clavicle fracture combined with coracoclavicular (CC) ligament injury (type II, V) who received arthroscopically assisted fixation using a flip button device were evaluated for accuracy of reduction using 3-dimensional postoperative CT scan by measuring the degree of distal clavicular angulation and clavicular shortening. Results: Immediate postoperative plain radiograph confirmed restoration of the CC distance (CCD) in 10 patients. At final follow-up, the CCD remained reduced anatomically on plain radiographs in these patients. All patients showed excessive posterior angulation and shortening compared to the opposite side. The average Constant score recovered to 94.8 at final follow-up. Conclusions: Indirect reduction and arthroscopic subacromial approach with flip button fixation of unstable distal clavicle fractures demonstrated favorable clinical results despite unavoidable posterior angulation of distal clavicle and shortening the total length of clavicle.

Spontaneous hemopneumothorax is a rare disease, and it can cause life threatening condition. It is characterized by the accumulation of more than 400 mL of blood and air in the pleural cavity without any other apparent causes. A previously healthy 22-year-old female patient presented with acute chest pain and dyspnea. Chest X-ray and computed tomography revealed a massive hemopneumothorax in the left hemithorax. The images showed a completely collapsed left lung with right-sided tracheal deviation, several pleural adhesion bands, and fluid collection with air-fluid level. We emergently performed a closed thoracostomy, and then 560 mL of fresh bloods were initially drained. We considered an emergent video-assisted thoracoscopic surgery for pulmonary wedge resection and bleeding control because of the massive hemothorax. However, the patient's vital signs were stabilized after blood transfusion and supportive cares for re-expansion pulmonary edema. The patient discharged from the hospital on 11^th in-hospital day after removal of the chest tube, and there had not been any recurrence of the pneumothorax for 10 months. We suggest that treatment strategy should be decided upon individually based on the patient's condition and clinical course of the disease.

We present a case of congenital cystic adenomatoid malformation (CCAM) in a 25-year-old male who was presented with chronic cough. Chest radiography revealed an abnormal mass-like shadow in the right lower pulmonary zone. A contrast enhanced computed tomography showed an 11 cm solid, cystic mixed mass on the right lower lobe. A right lower lobectomy was performed by video-assisted thoracoscopic surgery without complications. The gross specimen showed a massive cavitation with multiloculated cysts of varying size, consistent with CCAM, along with noticeable granulomatous inflammation. Non-tuberculosis mycobacteria were isolated from a bronchial wash specimen, and the resected tissue homogenates were positive for Mycobacterium avium-intracellulare complex by polymerase chain reaction.
