We report a case of a paradoxical response of a tuberculoma in the brain mimicking a brain tumor. A 76-year-old woman presented with a 2 week history of headache, dysarthia, and orthopnea. Brain magnetic resonance images (MRI) revealed two rim-enhancing lesions on the pons and occipital lobe, and chest computed tomography showed randomly distributed miliary nodules. The tentative diagnosis was tuberculosis (TB) of the brain and lung. She complained of right hemiparesis and worsening general weakness after taking the anti-TB medication. On the monthly follow-up images, the enhanced lesions were enlarged with increased perfusion and choline/creatinine ratio, suggesting a high grade glioma. A surgical resection was completed to diagnose the occipital lesion, and the tuberculoma was pathologically confirmed by a positive TB-polymerase chain reaction. The anti-TB medication was continued for 13 months. A follow-up MRI showed decreased size of the brain lesions associated with perilesional edema, and the clinical symptoms had improved. Brain tuberculoma could be aggravated mimicking brain malignancy during administration of anti-TB medication. This paradoxical response can be effectively managed by continuing the anti-TB drugs.

Background: Lesions in distal target arteries hinder surgical bypass procedures in patients with peripheral arterial occlusive disease. Methods: Between April 2012 and October 2015, 16 patients (18 limbs) with lifestyle-limiting claudication (n=12) or chronic critical limb ischemia (n=6) underwent femoral-above-knee (AK) polytetrafluoroethylene (PTFE) bypass grafts with a bridging stent graft placement between the distal target popliteal artery and the PTFE graft. Ring-supported PTFE grafts were used in all patients with no available vein for graft material. Follow-up evaluations assessed clinical symptoms, the ankle-brachial index, ultrasonographic imaging and/or computed tomography angiography, the primary patency rate, and complications. Results: All procedures were successful. The mean follow-up was 12.6 months (range, 11 to 14 months), and there were no major complications. The median baseline ankle-brachial index of 0.4 (range, 0.2 to 0.55) significantly increased to 0.8 (range, 0.5 to 1.0) at 12 months (p<0.01). The primary patency rate at 12 months was 83.3%. The presenting symptoms resolved within 2 weeks. Conclusion: In AK bypasses with a diffusely diseased distal target popliteal artery or when below-knee (BK) bypass surgery is impossible, this procedure could be clinically effective and safe when used as an alternative to femoral-BK bypass surgery.

Background: The inferior vena cava filter (IVCF) is very effective for preventing pulmonary embolism in patients who cannot undergo anticoagulation therapy. However, if a filter is placed in the body permanently, it may lead to other complications. Methods: A retrospective study was performed of 159 patients who underwent retrievable Cook Celect IVCF implantation between January 2007 and April 2015 at a single center. Baseline characteristics, indications, and complications caused by the filter were investigated. Results: The most common underlying disease of patients receiving the filter was cancer (24.3%). Venous thrombolysis or thrombectomy was the most common indication for IVCF insertion in this study (47.2%). The most common complication was inferior vena cava penetration, the risk of which increased the longer the filter remained in the body (p=0.032, Exp(B)=1.004). Conclusion: If the patient is able to retry anticoagulation therapy and the filter is no longer needed, the filter should be removed, even if a long time has elapsed since implantation. If the filter cannot be removed, it is recommended that follow-up computed tomography be performed regularly to monitor the progress of venous thromboembolisms as well as any filter-related complications.

MALT 림프종은 안구, 침샘, 감상선, 폐, 위, 소장, 대장, 방광, 여성 생식기에 발생하며, 대부분이 단일기관을 침범하고 국소 치료와 화학요법에 좋은 예후를 보인다. MALT 림프종이 기관을 침범하는 경우는 거의 보고된 경우가 없으며 국내에선 폐의 MALT 림프종이 보고된 적이 있었다. 이에 저자 등은 기관과 대장에 발생한 원발성 MALT 림프종 1예를 문헌 고찰과 함께 보고하는 바이다.

Pheochromocytomas are neuroendocrine tumors of chromaffin cell that originate in the paraganglia of the adrenal medulla. Approximately 10% of pheochromocytomas are found in the extra-adrenal paraganglia and are called paragangliomas. However, cases of middle mediastinal paragangliomas are very rare. In this case, the patient presented with a voice change and a headache. A middle mediastinal soft tissue mass with marked enhancement was detected on computed tomography of the chest. The 24-hour urine catecholamine level was markedly elevated. The middle mediastinal mass was biopsied via mediastinoscopy and the resulting immunohistochemical staining was compatible with a diagnosis of middle mediastinal paraganglioma. The mass was resected surgically and the symptoms were relieved.

Pancreaticothoracic fistula is a rare complication of acute or chronic alcoholic pancreatitis. It may present with various symptoms, like dyspnea, abdominal pain, cough, chest pain, fever, back pain, hemoptysis, fatigue, or orthopnea. Pancreaticothoracic fistula can be detected by magnetic resonance cholangiopancreatography (MRCP), endoscopic retrograde cholangiopancreatography (ERCP), or computed tomography. MRCP has high sensitivity and fewer side effects, and thus it has recently been recommended as the first choice for the detection of pancreaticothoracic fistula. On the other hand, ERCP enables the detection and treatment of pancreaticothoracic fistula and allows for stent insertion; for this reason it is a commonly used modality in pancreaticothoracic fistula cases. Herein, the authors describe a case of pancreaticothoracic fistula detected by ERCP and MRCP that manifested only respiratory symptoms, namely hemoptysis and pneumothorax without abdominal pain, which commonly accompanies pancreatitis.

간엽성 연골육종은 전형적인 연골육종과는 달리 매우 드문 것으로 알려져 있으며, 골격계 부위에서는 하지, 특히 대퇴골에서 대부분 발생하며, 다음으로 두안면부, 골반부에서 발생하는 것으로 보고되어 왔다. 11세 남아가 좌측 후족부 통증으로 타 병원에서 양성 골 종양 추정 하에 수술적 제거술을 시행 받고, 수술 후 조직검사 결과, 악성 종양으로 진단되어, 본원으로 전원 되었다. 조직 재 판독 결과, 좌측 종골 간엽성 연골 육종으로 진단되어, 슬하부 절단을 시행하였다. 외래 경과 관찰 중 술 후 3개월에 흉부 컴퓨터 촬영상 다발성 폐 전이성 결절 소견 보여 전이절제술 및 항암 치료를 시행하였다. 문헌상 간엽성 연골육종이 족저부 연부 조직에 발생한 경우는 1예가 있으나 종골 골조직에 발생한 경우는 없어 문헌 고찰과 함께 보고하는 바이다.

흉쇄 관절의 화농성 관절염은 드문 질환으로 정맥주사 약물 남용, 당뇨 그리고 외상 등과 같은 선행성 요인과 연관되어 주로 발생한다. 진단이 지연될 경우 종격동염, 흉벽 농양 등과 같은 위험한 합병증이 발생할 수 있으므로 전산화 단층촬영이나 자기공명영상 검사 등을 시행하여야 하고 종격동염 및 흉벽 농양 등과 같은 합병증 발생 시는 흉쇄 관절 절제술을 고려하여야 한다. 저자들은 감염 유발 소인이 전혀 없는 건강한 52세 남자에서 발생하였으며 균 배양 검사상 포도상구균으로 동정되었고 감수성 항생제인 cefminox(첫 4주는 정맥주사, 그 후 2주는 경구투여)만으로 치유되었던 일차성 흉쇄 관절 화농성 관절염에 대해 보고하는 바이다.

폐 말초에 발생한 고립성 결절의 증례가 점차 늘고 있다. 저자들은 이러한 폐결절에 대하여 방사선학적으로 양, 악성의 감별이 어느 정도 유용한가를 알아보고자 하였다. 대상과 방법: 직경 3cm 이하의 폐 말초에 발생한 고립성 병변증례 134예에 대하여 술전에 시행된 고해상 CT (HRCT)에서 결절 내부의 성상과 경계부 형태, 그리고 주변 폐실질과의 관계에 대하여 관찰하였다. 결과: GGA 면적비가 50% 이상인 경우는 선암과 일부 전이성 폐암 그리고 염증성 병변에서만 관찰되었으며, 90% 이상인 경우는 선암에서만 존재하였다. 반면에 비선암성 폐암과 양성 폐종양, 그리고 결핵종에서는 모두 GGA 면적비가 50% 이하였는데, 특히 10% 미만이 대부분이었다. Air bronchogram, spiculation, lobulation, vascular involvement, 그리고 pleural indentation의 소견들은 주로 악성 병변에서 관찰되었는데, 특히 원발성 선암에서 30% 이상의 고발현도를 보였다. 결론: 대부분의 원발성 폐선암은 HRCT에서 특징적인 소견들을 보이고 있다. 따라서 이러한 소견들에 유의한다면 다른 병변들과의 감별에 많은 도움이 될 것으로 생각되었다.

Exogenous lipoid pneumonia occurs rarely in healthy people. In most cases, exogenous lipoid pneumonia is usually caused by aspiration of mineral, vegetable, or animal oil. We report the case of 42-year-old woman, who have experienced lipoid pneumonia after silicon injection into her breast for cosmetic purposes. The patient experienced fever, dyspnea, sputum, and hemoptysis after silicon injection into her breast. Chest computed tomography demonstrated non- segmental distribution of bilateral consolidation in both lung fields. A transbronchial lung biopsy specimen shows foamy microphages in alveolar spaces. Papanicolaous staining of bronchoalveolar lavage fluid showed abundant foamy marcrophages and many neutrophils. With these results, we confirmed lipoid pneumonia was associated with silicon oil injection into breast.
