Primary dissection of the renal artery is rare. Spontaneous renal artery dissection can be associated with diseases such as medial degeneration, neurofibromatosis, syphilitic arteritis, tuberculosis, polyarteritis nodosa, Marfan syndrome, fibromuscular dysplasia, or Ehlers-Danlos syndrome (EDS). Among these causes, EDS related renal artery dissection is very rare worldwide and has not been previously reported in Korea. EDS are a group of heritable connective tissue disorders characterized by fragility of the skin and hypermobility of the joints. We describe the case history of a young man who presented with left side flank pain, hypermobility of the hand joints and showed left renal artery dissection on computed tomography and angiography that turned out to be the first complication of vascular type EDS.

A 21-year-old male visited our emergency room. He could not remember the mechanism of injury. He was found beside a motorcycle. Initial vital sign was stable. Observation and conservative treatment were planned at the intensive care unit (ICU). On the third day at ICU, he complained sudden flank pain. It was colicky and hard to control. Without the pain, he had no specific symptom, sign, or laboratory findings. On computed tomography, renal pelvis was filled with hematoma which induced hydronephrosis. Double-J catheter and percutaneous nephrostomy was implemented by an intervention radiologist. Hematome in the renal pelvis was aspirated during the procedure. Symptom of the patient was subsided after the procedure. He was discharged without specific complications.

Renal cell carcinoma (RCC) is common primary tumor of kidney. In the past, it had been considered a difficult tumor to manage since the detection was usually delayed until paraneoplastic syndrome and/or distant metastasis appeared due to its slow progression. However, the recent popularization of ultrasound and computed tomography has made RCC one of the easily curable cancers. Eighty percent are found early, mostly with tumor size less than 5 cm. Five-year survival rate after successful nephrectomy is exceeded 80-90 percent. Curative nephrectomy can be tried in stage 1 and 2, and some cases of stage 3. In these cases, return to flight can be considered after 6 to 12 months' observation. It should be monitored any occurrence of cancer recurrence, need for systemic treatment, metastasis, and paraneoplastic syndrome, etc. If any signs of recurrence are found or new treatment needs to be initiated, the flight should be suspended. If there is no recurrence for more than 5 to 10 years, the patient doesn't have to be followed anymore.

A two-year-old, intact female Golden Retriever had previously been diagnosed with a portosystemic shunt (PSS) during an ultrasonographic examination at a local animal hospital. The serum biochemistry revealed elevated liver enzymes and bile acid levels. The abdominal radiographic examination revealed mild serosal detail loss and microhepatica, while abdominal ultrasonography revealed mild ascites and high-velocity flow to the caudal vena cava (CVC) suspected as a PSS. The gallbladder was not observed within the hepatic parenchyma during ultrasonography. Computed tomography (CT) revealed an absent gallbladder and dilation of the common bile duct (CBD). Dilations of the gastroduodenal, splenic, colic and renal veins were also observed. A dilated left phrenico-abdominal vein that entered the CVC was previously misinterpreted as a PSS on the ultrasound examination. Based on the imaging examinations, the dog was diagnosed with congenital gallbladder agenesis associated CBD dilation.

Aim: The aim of the present study was to evaluate retrospectively histopathologically-diagnosed lesions that were detected in the kidney after radical nephrectomy for a preoperative diagnosis of kidney cancer. Methods: The medical records of 83 patients (51 male, 32 female) were included. Preoperative staging was accomplished by various methods including physical examination, blood hemography and biochemistry, abdominal ultrasonography (US), chest x-ray, abdominal computed tomography (CT) and abdominal magnetic resonance imaging (MRI). Results: Totals of 70 patients underwent radical nephrectomy and 13 nephron sparing surgery. Of the 83 patients, 70 had malignant lesions (renal cell carcinoma, squamous cell carcinoma or other malignancies) 13 had a variety of benign lesions, the most frequently detected being oncoytoma (6), angiomyolipoma (3), xanthogranulamatous pyelonephritis (2), cortical cyst (1) and chronic pyelonephritic change (1). Conclusion: It was concluded that in spite of great technological developments regarding radiological imaging modalities such as US, CT and MRI, benign lesions might still be detected pathologically in patients who undergo radical nephrectomy with the preoperative diagnosis of renal cancer. But, all renal masses should be regarded as malignant and should be managed surgically otherwise proven benign.

Objectives: The purpose of this study is to report the effect of Korean Herbal Medicine (KHM) on a Renal Cell Carcinoma with multiple liver metastases patient. Methods: One renal cell carcinoma with multiple liver metastases patient was treated by KHM in conjunction with targeted anticancer agent (Afinitor). The effect of KHM was measured by scanning with Computed Tomography (CT), Blood Test, Visual Analogue Scale (VAS) and Eastern Cooperative Oncology Group scale. Results: Multiple hepatic tumors were reduced after the treatment during 5 months (Partial Remission, PR). As treatment was performed, complications induced by targeted anticancer agent (Afinitor) were alleviated. Conclusions: This case provides us a possibility that Korean Herbal Medicine offers potential benefits for renal cell carcinoma with multiple liver metastases patient.

동적 컴퓨터단층촬영을 이용하여 연령에 따른 CT-GFR 수치에 대한 패턴을 살펴보기 위해 본 연구를 실시하였다. 품종이나 성별에 대한 제한 없이 다양한 연령으로 15마리의 개를 이용하였다. 혈액검사, 요검사, 영상학적 검사를 실시하여 개의 건강 상태를 확인한 후, propofol-isoflurane을 이용한 호흡마취를 실시하여 CT 촬영을 하였다. Iohexol (1 ml/kg, 300 mgI/ml)을 3 ml/s 일정한 속도로 2분간 주입하면서 1.5초 간격으로 총 80개의 영상을 촬영하여 파트락 분석을 통해 사구체여과율 (ml/min/kg)을 측정하였다. 양측 신장의 사구체여과율의 범위는 2.57-6.60 ml/min/kg이었다. 연구에서 연령에 따라 사구체여과율의 유의적인 차이는 확인되지 않았다.

The increased use of cone-beam computed tomographic (CBCT) scans has made it increasingly necessary to evaluate incidental findings on CBCT scans. This report describes the case of a 66-year-old female patient who presented to the Department of Oral and Maxillofacial Pathology, Radiology and Medicine at the College of Dentistry of the author's institution and underwent a CBCT scan for maxillary alveolar process implant planning. Upon evaluation of the CBCT scan, a radiopaque (soft tissue attenuation) mass in the left superior aspect of the nasal cavity and left locule of the sphenoid sinus with opacification of the left locule of the sphenoid sinus was incidentally noted. These radiographic findings were suggestive of a space-occupying mass with a high possibility of malignancy. A further medical evaluation confirmed renal cell cancer metastasis to the sphenoid sinus. This study shows the significance of reviewing the entire CBCT scan for incidental findings.

니볼루맙을 사용하는 도중 폐렴이 발생할 수 있고, 폐렴이 의심되면 치료하기 이전에 바이러스를 포함한 감염 여부와 림프관성 암의 진행 상태 및 울혈성 심장 기능 상실 여부 등의 감별이 필요하며 폐렴의 등급과 중증도를 평가하여 스테로이드를 경험적으로 쓰는 것이 중요하다. 본 증례에서는 감염을 배제하기 위하여 기관지 폐포세척을 시행한 후 폐포자충 폐렴이 진단된 사례로 드물기는 하지만 페포자충 폐렴의 감별이 필요함을 보여주어 증례로 보고하는 바이다.

An arteriovenous fistula (AVF) from the renal artery following a penetrating abdominal trauma is not common. We report the case of a 19-year-old male who presented with a knife stab wound in the right upper quadrant. Due to unstable vital signs and to the protrusion of the mesentery through the stab wound, providing definite evidence of peritoneal violation, an emergent exploratory laparotomy was carried out. There were injuries at the proximal transverse mesocolon and the second portion of the duodenum, with bile leakage. There was also a mild amount of retroperitoneal hematoma near the right kidney, without signs of expansion or pulsation. The mesocolon and the duodenum were repaired. After the operation, abdominal computerized tomography (CT) was performed, which revealed contrast from the right renal artery shunting directly into the vena cava. Transcatheter arterial embolization with a coil and vascular plug was performed, and the fistula was repaired. The patient recovered completely and was discharged without complication. For further and thorough evaluation of an abdominal trauma, especially one involving the retroperitoneum, a CT scan is recommended, when possible, either prior to surgery or after surgery when the patient is stabile. Furthermore, a lateral retroperitoneal hematoma and an AVF after a penetrating trauma may not always require exploration. Sometimes, it may be safely treated non-operatively or with embolization.
