A routine chest radiograph in a 10 months old male infant revealed a giant air filled cystic lesion of the left hemithorax under tension. At thoracotomy, a large left lower lobe intraparenchymal cyst required lobectomy and the pathological finding were consistent with a bronchogenic cyst. This kind of parenchymal bronchogenic cyst is uncommon lesion, and we have performed successful surgical resection. After this lobectomy, this patient was complete recovered and postoperative course was uneventful.

Background: For normalization of displaced anatomical structure by large cyst, two-step procedure (decompression and enucleation afterward) has been recommended. However, the histological transformation after cystotomy for decompression was shown frequently in secondary enucleation. Therefore, analyses about effects and histological changes after decompression have been necessary. Methods: 48 cases diagnosed as large odontogenic cyst in the jaw and treated by decompression and secondary enucleation were retrospectively analyzed in clinical, rediographical, and histological aspects. Results: In dentigerous cyst, decompression was much useful. Impacted permanent teeth were erupted and reduction rate was higher than that of odontogenic keratocyst (OKC) and apical periodontal cyst. In OKC, among the 29 cases, 11 cases showed no-keratosis, proliferation and rete-ridge elongation after decompression. 4 cases showed no-keratosis, only. 7 cases showed orthokeratosis and rete-ridge elongation and 6 cases showed reteridge elongation, only. 1 case had no change. And the recurrence rate for OKCs was 10.3%. For all odontogenic cysts in this study, dysplasia was not found in cystic lining after decompression. Conclusions: This study implied that decompression for large odontogenic cyst was useful treatment modality because it was conservative treatment and recurrence rate was low although long treatment period was required.

The authors had a case of large periodontal cyst treated by Apicoectomies in 32 year old, Korean female. 1. A large periodontal cyst revealed big size in Maxilla, left side. 2. The authors have treated the periodontal cyst by means of the apicoectomies of the involved left lateral incisor, canine, 1st premolar and 2nd premolar teeth, maxilla. 3. Radiographic examination revealed a large radiolucent lesion 2.7 3.7cm in diameter, in the midline area, with involvement of the lateral incisor, canine, 1st premolar and 2nd premolar teeth, maxilla.

A 6-year-old intact male Doberman pinscher presented with a thin soft stool and urinary signs. On radiography, three masses were observed in the caudal abdomen. One mass was described as a large, round, mineralized mass, with an "eggshell" appearance. The second mass was located caudal to the mineralized mass, and the third mass was located between the two masses. The second and the third masses had a soft tissue density. Ultrasonography was performed to identify the features and the origins of the masses. The first mass contained a large amount of anechoic fluid and had a thin wall; it was determined to be a cyst. Strong acoustic shadowing artifact was created by the mineralized cystic wall. Caudal to the cyst, the second mass was shown to be the prostate. A hypoechoic stalk connected the prostate and the cyst, which represented the cyst as a paraprostatic cyst with mineralization. The third mass was the normal urinary bladder. The cyst was removed surgically and confirmed by histopathologic examination. This report described typical clinical findings, diagnostic imaging, and treatment of a paraprostatic cyst.

We report a rare case of symptomatic Rathke's cleft cyst with thick calcified wall. Brain CT scans revealed a large cystic mass with round thick calcified wall. In this case, we selected the pterional approach instead of transsphenoidal approach due to the possibility of cystic craniopharyngioma. Histopathologically, it was calcified Rathke's cleft cyst with focal epithelial metaplasia. This case illustrates that calcification of the suprasellar cyst does not always suggest craniopharyngioma and the calcification pattern of Rathke's cleft cyst is different from that of the craniopharyngioma.

Cyst is a closed sac, having a distinct membrane and division compared to the nearby tissue. Most cysts in the oro-maxillofacial area are odontogenic origin and found most commonly by oral and maxillofacial surgeons. Enucleation is considered as a definitive therapy in the management of these cysts. However, to select the treatment method for large cyst, consideration of position of the cyst, size and accessibility to main structure are needed. Marsupialization is a minimal invasive technique to treat large odontogenic cyst and tumor without damage to adjacent important structures. This study was undertaken to describe three cases of odontogenic cysts and tumors of jaws that were successfully treated with enucleation after marsupialization.

First of all a good surgical access is considered among various approach methods to the cystic lesion. A poor surgical access can lead to a failure of the whole treatment. A sagittal split ramus osteotomy (SSRO) on the large cyst occurring in the mandibular ramus lets us not only reduce operation time, but can additionally contribute to a good visual field. In addition, a merit exists that it lets this operating method provide soft tissue adhesion for proximal and distal segment and decrease post operative necrosis. We experienced three cases of a large cyst on the mandibular angle and ramus. By employing a sagittal splitting of the mandible, it provided good surgical access and operation results without recurrence during a follow-up period. The surgical technique described may be helpful in treating similar large cysts.

A dermoid cyst is a rare congenital midline neck mass with usually develops in the submental region. It is most often seen in young adults and can become rather large than almost no symptoms. As it increases in size, dysphasia, or dyspnea can develop. The differential diagnosis of the midline lesion includes ranula, thymglossal duct cyst, cystic hygroma, and cystic lymphangioma. The treatment of choice is complete surgical removal. With a review of the literature, we report two cases of a huge dermoid cyst inducing dyspnea.

Keratocystic odontogenic tumors can occur in any area of the maxilla or mandible. According to their size, location, and relations with surrounding structures, they are treated by cyst enucleation or enucleation after either marsupialization or decompression. Enucleation is performed when cysts are not large and when only minor damage to adjacent anatomical structures is expected. Although marsupialization and decompression follow the same basic bone-regeneration principle, which is to say, by reducing the pressure within the cyst, the former leaves a large defect after healing due to the large fistula necessary to induce the conversion of the cyst-lining epithelia to oral epithelia; the latter leaves only a relatively small defect, because of the continuous washing carried out by means of a tube inserted into a small hole in the cyst. In the latter case too, a decompressor appropriate for the focal position is required, owing to the importance of maintaining the device and controlling for oral hygiene. We report herein decompression treatment with a patient-customized device for an extensive cyst in the anterior region of the mandible.

Discal cyst is an intraspinal cyst with a distinct communication with the corresponding intervertebral disc. It is a rare condition and could present with radiculopathy similar to that caused by lumbar disc herniation. We present a patient with a large discal cyst in the ventrolateral epidural space of the $5^{th}$ lumbar vertebral (L5) level that communicated with the adjacent $4^{th}$ lumbar and $5^{th}$ lumbar intervertebral disc, causing L5 radiculopathy. We alleviated the radiating pain with selective transforaminal epidural blocks.
