The cerebral vasospasm after clipping surgery of unruptured aneurysm is uncommon. A 44-year-old man with unruptured left middle cerebral artery[MCA] aneurysm had clipping surgery. From the third postoperative day, he presented with drowsy mentality, dysphasia and right hemiparesis. Computed tomographic scans showed low density area in frontotemporal lobe and midline shift. Transfemoral cerebral angiography revealed severe vasospasm in supraclinoid internal carotid artery, anterior cerebral artery, and MCA on the operative side. We performed left frontotemporoparietal craniectomy and hypertensive-hypervolemic therapy. He recovered without neurological deficits but for dysphasia. Neurosurgeon should be alert to the possibility of vasospasm after clipping surgery even in case of unruptured cerebral aneurysm.

I clinically analysed 13 cases of broncholithiasis which treated surgically and found only four cases of broncholithiasis caused by the erosion of the peribronchial lymph node named by extrinsic formation[Group II], and nine cases of broncholithiasis caused by intrinsic formation[group I] which indicates that no evidence of the erosion of the calcified per-ibronchial lymph node into the bronchial tree was found. This study is performed to see any differences between two groups regarding presenting symptoms, locations of broncholith, preoperative diagnosis, a history of pulmonary tuberculosis, a procedure of operation, and chemical compositions of broncholiths from both groups. There was no difference between two groups in the presenting symptoms, the procedure of operation, and chemical compositions of broncholiths. The broncholits from group two is located in the right middle lobe bronchus, and the broncholiths of group one were distributed at various bronchi, In group one, only five cases out of nine had preoperative diagnosis[55.5%], but in group two, all four had preoperative diagnosis. All cases had good postoperative courses without any complication and recurrences.

In this paper, I present the technique of subxiphoid single-port video-assisted thoracic surgery (VATS) thymectomy for thoracic surgeons to perform this procedure safely. This procedure is indicated for all anterior mediastinal masses and may be extended to lung cancer. The patient is placed in the lithotomy position, and the operator should be on the midline. Below the xiphoid process, a skin incision is made 4-5 cm horizontally at a single thumb's width down. Under two-lung ventilation, CO₂ is insufflated, maintaining 10 mm Hg. The fat tissue and thymic tissue are all resected from the sternum and pericardium between both phrenic nerves using an articulated grasper and an energy device. After retrieval of the mass with a wrap bag, a Jackson-Pratt drain is inserted instead of a chest tube. One of the advantages of this procedure is less postoperative pain than intercostal VATS. The subxiphoid approach can be used for bilateral pneumothorax, bilateral pulmonary metastasectomy, and simple lobectomy for both upper lobes and the right middle lobe.

Primary malignant lymphoma of the lung is a very rare disease, which consists of 0.34% of entire malignant lymphoma. The majority are low-grade B-cell tumors, and because of their morphological peculiarities and overall excellent prognosis, many cases, like many other extranodal lymphomas, have been mislabelled as "pseudolymphomas" in the past. For these reasons their true incidence is difficult to estimate. An incidentally discovered mass in the right middle lobe of a 36-year-old woman was operated on November 9, 2001 at Hanyang University Hospital. A right upper lobectomy was done and the pathologic diagnosis of extranodal marginal zone B-cell lymphoma of MALT type was made.

We present a case of tacrolimus-induced encephalopathy after successful kidney transplantation. An 11-year-old girl presented with sudden onset of neurologic symptoms, hypertension, and psychiatric symptoms, with normal kidney function, after kidney transplantation. The symptoms improved after cessation of tacrolimus. Magnetic resonance imaging (MRI) showed acute infarction of the middle cerebral artery (MCA) territory in the right frontal lobe. Three days later, she had normal mental function and maintained normal blood pressure with left hemiparesis. Follow-up MRI was performed on D19, showing new infarct lesions at both cerebral hemispheres. Ten days later, MRI showed further improvement, but brain single photon emission computed tomography (SPECT) showed mild reduction of uptake in both the anterior cingulate gyrus and the left thalamus. One month after onset of symptoms, angiography showed complete resolution of stenosis. However, presenting as a mild fine motor disability of both hands and mild dysarthria, what had been atrophy at both centrum semiovale at 4 months now showed progression to encephalomalacia. There are two points of interest in this case. First, encephalopathy occurred after administration of tacrolimus and improved after discontinuation of the drug. Second, the development of right-side hemiplegia could not be explained by conventional MRI; but through diffusion tensor imaging (DTI) and diffusion tensor tractography (DTT) of white matter tract, visualization was possible.

비정형 폐기관지 카시노이드(carcinoid)는 드문 폐 종양으로 기원이 신경호르몬 종양으로 사려되며 전형적인 카시노이드와 소세포암 사이의 중간 정도의 악성도를 나타내는 형태이다. 저자들은 무증상이며, 호르몬 생성을 보이지 않은 비정형 카시노이드를 수술치험 하였다. 환자는 49세 여자환자로 단순흉부촬영상 우연히 발견된 우하엽의 종괴를 주소로 내원하였다. 기관지 내시경하 조직검사에서 진단되어 우하엽 및 중엽 절제술과 종경동 임파선 박리술을 시행받고 술후 4주후에 방사선 치료를 받았다.

성인에서의 잠복 기관지 이물은 소아의 기관지내 이물 흡인과 달리 매우 드물며 아직까지 기관지나 폐의 연관손상 정도와 잠복기간에 따른 치료전략이 정립되어 있지 않은 상태다. 과거력상 반복적인 기침과 객담, 발열을 경험하였으나 30년 전에 사인펜 뚜껑이 기도내로 흡인되었던 사실을 인지하지 못하던 40세 남자 환자가 동일 주소와 영상검사상 우중엽 및 하엽의 허탈과 폐쇄성 폐간질염 소견으로 전원되었다. 처음엔 기관지경 이물 제거와 내과적 치료를 계획하였으나 제거가 불가능하였고 결국 개흉후 양엽 절제를 통해 치료하였다. 저자들은 본 증례가 잠복성 기관지 이물의 다양한 임상상 축적에 중요한 정보를 제공하였다고 생각한다.

저자들은 우중엽 폐렴 환자에서 대량객혈이 발생하여 기관지동맥색전술을 시행하고, 기관지내시경상 우중엽 외측 구역기관지를 막고 있는 기관지결석을 발견하여 조직검사상 Aspergillus에 의한 기관지결석임을 증명하였기에 문헌고찰과 함께 보고하는 바이다.

기관지내 평활근종은 기관지의 폐쇄정도에 따라 호흡곤란, 기침, 천명 등의 다양한 증세를 동반하며 그 증상이나 폐쇄정도가 경미할 경우 흉부 X-선 검사에서는 이상소견이 관찰되지 않을수도 있다. 따라서 폐렴이나 천식 등의 치료를 하다가 뒤늦게 발견되는 경우가 있는데 이 경우 반복적인 폐쇄성 폐렴과 폐농양, 기관지 확장증 등의 비가역적인 폐손상이 유발되며, 이는 전폐 절제술 등의 치료를 요하기도 한다. 따라서 무엇보다도 기관지내 평활근종의 치료 목표는, 증상에 따른 기관지내 병변의 의심과 기관지경에 의한 정확한 조기 진단과 보존적 수술, 내시경적 치료에 의해 비가역적인 폐손상을 방지하고 폐기능을 최대한 유지하는 것이다. 본 증례는 항생제 치료에 반응하지 않는 지속적인 폐렴으로 전원되어 온 환자에서 기관지경시행 후 기관지내 평활근종을 진단한 경우로, 이와 같은 경우 기관지내 병변의 가능성에 대해 반드시 고려하고 조기에 기관지경을 시행하여 정확한 진단을 하는 것이 무엇보다 중요하다고 하겠다.
