  • Ankylosis of joint is defined as limited movement due to infection, trauma, or surgical procedure. A 59-year-old female with a chief complaint of limited movements during mouth opening had a positive history of trauma to her right TMJ area about 5 years ago. From that time, progressive mouth opening limitation and intermittent pain have occurred. At the time of admission the patient showed mandibular deviation to the right side during mouth opening, with a maximum opening limited to 5 mm. On plain radiographs, right condylar enlargement and joint space reduction by newly formed bony tissues were observed. CT scans showed right condylar enlargement, cortical sclerosis, and thickening of the condyle, articular fossa and articular eminence.

  • 실리콘의 부적절한 피하 주입으로 발생한 폐색전증의 방사선학적 특징은 초기에는 호흡기 증상만 보이지만 염증 매개성 반응이 진행함에 따라 양측 폐 침윤이 급격히 진행하는 것을 볼 수 있었다. 또한 실리콘의 비중이 혈액보다 낮아 중력 비의존성 분포를 보임을 알 수 있었고, 이는 기존의 다른 원인에 의한 폐색전증과 구분되는 소견이다.

  • Osteochondroma is a common bone tumor but a rare tumor in the rib. It is often asymptomatic and observed incidentally. This is a case report of a 49-year-old woman with an osteochondroma mimicking a mediastinal mass in hereditary multiple exostoses. The chest X-ray and computed tomography (CT) scans revealed the bony density feature of the mass. Surgical excision confirmed that the lesion was an osteochondroma.

  • Objective: To explore the association of serum tumor abnormal protein (TAP) with other serological biomarkers e.g. carcinoembryonic antigen (CEA), carbohydrate antigen 125 (CA125), carbohydrate antigen 19-9 (CA19-9) and its clinical application in colorectal cancer (CRC) patients. Methods: Patients (N=98) were enrolled into this study with histologically or cytologically confirmed CRC. Using a test kit, the level of TAP was determined, while chemiluminescence was used to measure the levels of some other common serological biomarkers e.g. CEA, CA125 and CA19-9. Results: The area of TAP condensed particulate matter decreased after chemotherapy compared with before chemotherapy when CT or MRI scans showed disease control. In contrast, it increased with disease progression (P<0.05). Furthermore, a statistically significant difference was confirmed in monitoring of TAP and common serological biomarkers e.g. CEA and CA19-9 (p<0.05). Conclusions: Detecting TAP in CRC patients has high sensitivity and specificity and can be used as a new independent indicator for clinically monitoring CRC patients in the course of chemotherapy.

  • A 35-year-old man's vision had progressively deteriorated over a 3-month period. His left visual acuity was 5/20. Enhanced orbital computed tomographic (CT) scans revealed a fusiform dilatation of the ophthalmic artery in the left optic canal. Cerebral Angiography revealed a fusiform aneurysm on the left ophthalmic artery in the optic canal, measuring $6.2{\times}4.6\;mm$ in size. Four days after admission, visual acuity dropped to hand-motion. Endovascular treatment was chosen and a microcatheter was guided into the proximal segment of the ophthalmic artery. Using 4 detachable coils, parent artery occlusion was done. Three months after the intervention, the visual acuity in his left eye improved to 20/20. Dramatic recovery of visual acuity is exceptional with an ophthalmic artery trunk aneurysm. When an occlusion of the proximal ophthalmic artery is the only treatment option in such a situation, the endovascular occlusion of the proximal ophthalmic artery is quite feasible in the sense that it does not require any optic nerve manipulation.

  • Portal vein gas and pneumatosis cystoides intestinalis are uncommon conditions and have been associated with poor prognosis. They are most commonly caused by necrotizing enterocolitis but may have other causes, and they can be associated with necrotizing and ischemic colitis, intra-abdominal abscess, small bowel obstruction, diverticulitis, colon cancer, and acute pancreatitis. With the more frequent use of computed tomography (CT) scans, portal vein gas and pneumatosis cystoides intestinalis have been increasingly detected in recent years. Because of its high mortality rate, necrotizing enteritis with portal vein gas and pneumatosis cystoides intestinalis may be treated with emergent exploratory laparotomy. We report a case of necrotizing enteritis with portal vein gas and pneumatosis cystoides intestinalis in a 47-year-old man treated with intensive medical management and delayed operation due to unstable condition and surgical mortality. He had good clinical results without complications after the delayed operation.

  • Recently, many studies were reported accurate analysis of facemask effect due to the development of the personal computers and computer programs. The aim of this study is appropriate protraction direction of facemask using finite element study with computer aided design and computer aided measurement. The construction of the three dimensional FEM was based on the computer tomography(CT) scans of 13.5 year-old male subject. Protraction force of 500 mg was applied at 0, 30, 60 and 90 degrees downwards to the Frankfort horizontal plane, and maxillary displacement and stress distribution were measured. When 60 degree force was applied, it showed forward movement of premolar roots area and downward movement of anterior nasomaxillary area, and others showed clockwise rotation movement of the nasomaxillary complex. Finally, we can produce the protraction of maxillary bone without rotation of maxilla about 60 degrees.

  • Alveolar soft-part sarcoma(ASPS) is a rare, aggressive malignancy of uncertain histologic origin with a propensity for vascular invasion and distant metastasis. ASPS may mimic benign vascular neoplams of malformation but careful evaluation of the unique imaging features on CT scans, MR images, and angiograms lead to the correct diagnosis. ASPS of the tongue is slow-growing, painless mass, especially ASPS of the base the tongue is difficult to be noticed by patient, dentists or oral and maxillofacial surgeons on oral examintion because of its location and clinical resemblance to a benign lesion. And it leads to delayed or inadequate diagnosis. We report radiologic and clinical features of an ASPS of the basal portion of the tongue in a 17-year-old boy, showing normal appearance, but palpation of the tongue and floor of the mouth reveals the tumor. Among the 23 cases of a primary ASPS of tongue reported, 7 cases occured on the basal region of the tongue, inculding the present one. There has been no recurrence or metastasis as of 3 years postoperatively.

  • This nationwide survey was conducted to evaluate the current status of clinical practice for gastric cancer patients in Korea. The Information Committee of the Korean Gastric Cancer Association (KGCA) sent questionnaires containing 45 items about the preoperative diagnosis, medical and surgical treatment, and postoperative follow-up for gastric cancer patients to all 298 KGCA members in 108 institutes. Response rates were $32.6\%$ (97/298) for individuals and $59.3\%$ (64/108) for institutes. Most university hospitals responded (response rate of university hospitals: $71.6\%$, 48/67). The preoperative staging work up was performed primarily by abdominal CT, followed by bone scans, abdominal ultrasound, endoscopic ultrasound, and so on. Gastric cancer patients with stages II, III, and IV usually received adjuvant chemotherapy after a curative operation. About half of the surgeons regarded 2 cm as a safe resection margin in early gastric cancer and 5 cm in advanced gastric cancer. More than half of surgeons usually performed a D2 lymph node dissection in early gastric cancer and D2+$\alpha$ lymph node dissection in advanced gastric cancer. About $20\%$ of surgeons performed less invasive surgery and/or function-preserving surgery, such as a pylorus-preserving gastrectomy, a laparoscopic wedge resection, or a laparoscopy-assisted distal gastrectomy.
