이 연구의 목적은 기관지낭종의 CT소견을 분석하여 그 특징을 알아보고자 하였다. 수술후 조직학적으로 기관지낭종으로 확진된 11명의 CT소견을 후향적으로 분석하였다. 전 예에서 조영증강 전 후의 CT가 시행되었고 CT상 병변의 위치, 크기, CT 음영과 조영증강 정도, 석회화 유무 등을 중심으로 분석하였다. 총 11례중 3례는 폐실질내에 8례는 종격동내에 위치하였다. 폐실질내 기관지낭종 3례중 2례는 우하엽, 1례는 좌하엽에 위치하였고 평균 크기는 9.7 cm이었다. CT상 1례는 공기로만 찬 낭포, 1례는 균질한 물음영의 낭종, 1례는 공기방울을 가지는 고음영의 낭종으로 보였다. 종격동내 기관지낭종 8례 중 5례는 후종격동, 2례는 상종격동, 1례는 중종격동에 위치하였으며 평균 크기는 5.0 cm이었다. CT상 5례는 균질한 물음영으로 나타났고, 1례는 공기수면상을 보였으며, 2례는 근육과 비슷한 정도의 고음영으로 나타났고 그중 1례는 65 HU를 보였다. 모든 예에서 석회화나 조영증강은 보이지 않았다. 수술소견상 폐실질내 기관지낭종은 3례 모두에서 낭종내에 지저분한 농양의 액체를 가지고 있었고 종격동내 기관지낭종은 8례 모두에서 희거나 노란색의 점액질 액체를 보였다. 기관지낭종은 균일한 물음영을 보이는 경우가 가장 많으며, 그 외 근육과 비슷한 정도의 고음영, 공기수면상, 공기로만 찬 낭포 등으로 보였으며 이와 같은 소견은 기관지낭종의 진단과 감별에 도움이 될 것으로 생각한다.

Nasopalatine duct cysts are the most common non-odontogenic developmental cyst originating in the incisive canal of maxilla and occuring in approximately 1% of the population. Clinical presentation is mostly asymptomatic in small cysts, but sometimes shows swelling, pain and drainage when it is infected. The definite diagnosis should be based on clinical, radiological and histopathologic findings. Marsupialization of the cystic tissue can be performed, however, complete surgical excision is the the choice of treatment of nasopalatine duct cysts. We report a case of nasopalatine duct cyst occurred in the midline of hard palate treated by complete excision via transoral approach.

Cyst is pathologic disease develops in hard tissue as well as soft tissue, which is lined by epithelium filled with liquid, semi-liquid, or air. Origins and symptoms of the cyst are various according to region, and symptoms are malocclusion, diversion of root, tooth mobility, periapical swelling, discoloration and lesion expansion, because the odontogenic cysts begin in the numerous rests of odontogenic epithelium. But almost cysts produce no symptoms unless secondary infection occurs. Treatment of small cysts may include extraction, endodontic therapy, and apical surgery. Treatment of a large cysts usually involves surgical removal (enucleation), Marsupialization(a method of decompression) or combination of two before mentioned. Bone graft is done for helping of bone defect healing at the same time of enucleation This clinical research from January 2000 to December 2005, analyzed by the age, sex, classification, size, region, treatment method, whether or not of bone graft of cyst in the jaw in Daegu Catholic University Hospital.

The purpose of this study was to evaluate the systemic and local production of immunoglobulins and their levels in patients with periapical cysts using Enzyme - Linked Immunosorbent Assay. Streptococcus sanguis, Bacteroides gingivalis, and Bacteroides intermedius were grown for use as antigen and they were harvested by centrifugation. The patients were divided into two groups: patients of periapical cysts and normal control. 5 patients of each group were selected and their blood were obtained via intravenous puncture prior to surgical operation. Sera were prepared by centrifugation of each blood samples. Cyst fluid were aspirated from cystic cavity and cyst wall were excised at operation. Control tissue were also excised at extraction site of impacted wisdom teeth from normal control. Each tissue was prepared by homogenization and centrifugation. Then antibodies of each sample were measured by modified ELISA. The following results were obtained: 1. Serum IgG and IgM levels were not significantly different between patients with periapical cyst and normal control. 2. IgG and IgM levels of cyst fluid to Bacteroides gingivalis and Bacteroides intermedius were significantly higher than those of serum of patients with periapical cyst, but there was no significant difference to Streptococcus sanguis. 3. IgG and IgM levels of cyst wall to Bacteroides gingivalis and Bacteroides intermedius were significantly higher than those of control tissue, but there was no significant difference to Streptococcus sanguis. 4. IgG and IgM levels in cyst fluid and IgG levels in cyst wall were highest to Bacteroides gingivalis, and IgM levels in cyst wall were highest to Bacteroides intermedius.

Pulmonary histiocytosis X is an idiopathic benign disease characterized by proliferation and infiltration of lung tissue by characteristic Langerhans cells and eosinophils. Pulmonary histiocytosis X is common in young male adults, and shows variable clinical characteristics. We experienced a case of pathologically proven pulmonary histiocytosis X in a 30-year-old man who visit to our hospital due to chest discomfort and cough. The chest radiograph of our patient shows right pneumothorax and characteristic multiple thin-walled cysts on the both upper lung fields. The HRCT shows multiple thin-walled cysts, a few scattered nodules in both upper and right middle lung, and right pneumothorax.

A six-year-old, female Jin-do dog was referred for the recurrence of vaginal prolapse. Less than 7 months previously, the dog with the vaginal prolapse had been treated with hormone therapy because ultrasonography had identified a single follicular cyst in the left ovary. Three months after the first visit, the dog came into heat and the vaginal prolapse recurred. Ultrasonography showed multiple follicular cysts in both ovaries and radioimmunoassay detected a plasma estradiol-$17{\beta}$ concentration of 13.3 pg/ml. Treatment involved the repositioning of the vaginal prolapsed, ovariohysterectomy and the resection of the protruding tissue. The dog had been completely recovered two months later after the treatment.

A 16-year-old female Bengal tiger (Panthera tigris tigris) infected with Paragonimus kellicotti was described. Noticeable clinical symptom was not observed before death. At autopsy, numerous cysts were found on the pleural surface of the lung. The cysts were spherical, approximately 1.0 cm in diameter, bulge the pleura, and dark red-brown in color. Such cysts were also found in the deeper lung parenchyma, and usually contained adult flukes in pairs. Histopathologically, the cyst was lined with stratified squamous epithelium which arose from metaplasia of bronchial epithelium. Partial hyperplasia and necrotic foci accompanied with inflammatory cells were often observed in the squamous epithelium. The outer part of the cyst was consisted of fibrous connective tissue in which leukocytes were infiltrated. Catarrhal pneumonia was manifested in the adjacent lung tissues.

Sj${\ddot{o}}$gren's syndrome is a chronic autoimmune exocrinopathy that destroys salivary and lacrimal gland tissue. We report an unusual case of this disease in a 54-year-old woman who presented with multiple and bilateral parotid cystic masses. The multiple, small, bead-like cysts were clearly evident in the computed tomography sections in this patient, a visible reminder that this may be the initial presentation in a patient with Sj${\ddot{o}}$gren's syndrome. As the case illustrates, Sj${\ddot{o}}$gren's syndrome should be included in the differential diagnosis of multiple and bilateral cystic parotid lesions.

Objective : To retrospectively analyze the clinical characteristics and surgical experience of 10 adults with spinal extradural meningeal cysts (SEMCs) in the thoracolumbar spine which may further provide evidence for surgical decision-making. Methods : Ten adults with SEMCs in the thoracolumbar spine were surgically treated and enrolled in this study. Clinical manifestations, imaging data, intraoperative findings and postoperative outcome were recorded. Results : Clinical manifestations of SEMCs included motor and sensory dysfunction of the lower limbs and urination and defecation disturbance. The cysts presented as intraspinal occupying lesions dorsal to the spine, ranging from the T8 to L3 level. Defects of eight cases were found on preoperative magnetic resonance imaging (MRI). Selective hemilaminectomy or laminectomy were used to reveal the defect within the cyst, which was further sutured with microscopic technique. The final outcome was excellent or good in seven cases and fair in three cases. No recurrence was observed during follow-up. Conclusion : SEMCs are rare intraspinal cystic lesions. Radiography and MRI are clinically practical methods to assess defects within SEMCs. Selective hemilaminectomy or laminectomy may reduce surgical trauma. Detection and microscopic suturing of the defects are the key steps to adequately decompress the nervous tissue and prevent postoperative recurrence.

Purpose: Alloplastic implants, such as methylmethacrylate, Teflon, silicone, Supramid are commonly used to cover the floor defect and to prevent reherniation of the displaced orbital tissue in orbital floor fracture. Silicone implant has been used for reconstruction of orbital wall defects because of pliability, advantage of carving and chemically inert nature. However, silicone implant also has complications including infection, extrusion, pain, dystopia and tissue reaction. Cyst formation around the silicone implant is a very rare complication. According to many reports, cysts around alloplastic implant in an orbital area are mostly hemorrhagic cysts consisted of blood breakdown product with fibrous capsule cell in histologic examination. Methods: The authors report atypical case and successful treatment of intraorbital hemorrhagic cyst around silicone implant of a 37-year-old male patient. Results: Preoperative symptoms of diplopia, exophthalmos, proptosis, vertical dystopia and ectropion of lower eyelid were resolved after surgical removal of implants with surrounding capsule. Conclusion: Clinical suspicion of plastic surgeon is important in diagnosis of intraorbital cyst of patients who have history of silicone implantation and computed tomography is the standard tool of diagnosis. During the operation, caution must be taken on delivering the whole capsule of intraorbital cyst along with silicone implant to prevent recurrence of the cyst.
