Dermoid cysts are benign congenital tumors composed of keratinizing squamous epithelium and dermal derivatives. They account for less than 1% of all intracranial tumors and are rarely exhibited at the base of the skull. To the best of our knowledge, only one case report has presented computed tomography and conventional T1-weighted magnetic resonance (MR) findings that revealed an infratemporal dermoid cyst. In the present study, we report an unusual case of a dermoid cyst in the right infratemporal fossa, which was incidentally detected by MR imaging with the Dixon technique. This article also highlights the importance of meticulous radiological review and the usefulness of the Dixon technique in everyday clinical practice.

Mucocele of the paranasal sinuses is a benign, slow-growing, expansile lesion. Maxillary sinus mucoceles are usually associated with painless bulging of the cheek; however, orbital expansion is rarely observed. Maxillary sinus mucoceles can be classified as primary or secondary according to their etiology. An impediment to sinus ostium ventilation is thought to be the cause of primary mucocele, while sequestering of residual mucosa after surgery in the wound and long-term retention of tissue fluid have been suggested to lead to the formation of secondary mucocele. This report presents 2 cases of primary and secondary mucoceles, with a focus on radiographic features. As primary and superiorly positioned secondary maxillary sinus mucoceles are uncommon and their close proximity to the orbit predisposes the patient to significant morbidity, the authors expect that this report will contribute to a better understanding and diagnosis of maxillary sinus mucocele involving the orbit.

하장간막동맥은 산후출혈의 매우 드문 출혈 혈관이다. 저자들은 질분만 후 하장간막동맥에서 출혈이 있었던 일차성 산후출혈 두 개의 증례를 보고한다. 두 환자 모두 저혈량성 쇼크의 징후를 보이고 있었고, 파종성혈관내응고가 의심되는 상태였다. 산후출혈의 흔한 출혈 혈관인 자궁동맥을 색전한 후에도 출혈은 지속되었다. 하장간막동맥 혈관조영술에서 상직장동맥으로부터 조영제의 혈관외누출이 확인되어 N-butyl cyanoacrylate를 이용한 선택적 색전술을 시행하였다. 이 증례를 통해 산도 손상에 의한 산후출혈이 조절되지 않고 지속될 때 하장간막동맥이 출혈 동맥일 수 있다는 점을 강조하고자 한다.

랑게르한스 세포 조직구증은 희귀한 질환으로 일반적으로 근골격계를 침범하며, 대부분 소아에게서 발생하고 성인의 쇄골에서 발병하는 경우는 극히 드물다. 이 증례 보고는 50세 남자에게서 영상학적으로 발견되어 병리학적으로 확진된 쇄골의 랑게르한스 세포 조직구증의 사례이다. 또한 저자들은 문헌고찰과 함께 단순촬영, 컴퓨터단층촬영, 자기공명영상법, 그리고 양전자방출단층촬영-컴퓨터단층촬영 영상 등의 다양한 영상검사 소견을 보고하고자 한다.

췌공장문합술 후 췌관 내 스텐트를 삽입하는 것은 수술 후에 췌장루나 췌관 협착의 발생을 예방하기 위해 널리 시행하는 술기이다. 그러나 삽입한 스텐트가 막히거나 이동하는 등 스텐트에 의해서도 다양한 합병증이 발생할 수 있다. 저자들은 췌관에 삽입한 플라스틱 스텐트가 이동하면서 발생된 매우 드문 합병증의 예를 보고하고자 한다. 유문부 보존 췌두부십이지장 절제술 시행 후 췌장 내 삽입한 스텐트는 공장으로 이동하여 스텐트-돌 복합체의 근원으로 작용하여 공장 폐색을 일으켰다. 스텐트-돌 복합체는 탐색적 개복술로 제거되었다.

Disseminated peritoneal leiomyomatosis (DPL) is a very rare benign disease, characterized by multiple solid subperitoneal or peritoneal smooth muscle nodules in abdominopelvic cavity and malignant transformation is extremely rare. Also, uterine smooth muscle tumors of unknown malignant potential (STUMP) is a rare tumor, which is regarded as subclassification in uterine smooth muscle tumors between benign and malignant criteria. Pathogenesis of DPL is uncertain, but increasing evidence of iatrogenic cause including laparoscopic myomectomy has been reported. We report a case of a 28-year-old female with previous history of laparoscopic myomectomy diagnosed with DPL with atypical feature and concurrent uterine STUMP using computed tomography (CT) and magnetic resonance imaging (MRI), as well as present a review of the literature.

Nodular fasciitis (NF) is a benign myofibroblastic proliferation that grows very rapidly, mimicking a sarcoma on imaging. It is treated by local excision, and recurrence has been reported in only a few cases, even when excised incompletely. The most prevalent diagnoses of temporomandibular joint(TMJ) masses include synovial chondromatosis, pigmented villonodular synovitis, and sarcomas. Cases of NF in the TMJ are extremely rare, and only 3 cases have been reported to date. Due to its destructive features and rarity, NF has often been misdiagnosed as a more aggressive lesion, which could expose patients to unnecessary and invasive treatment approaches beyond repair. This report presents a case of NF in the TMJ, focusing on various imaging features, along with a literature review aiming to determine the hallmark features of NF in the TMJ and highlight the diagnostic challenges.

The calcifying epithelial odontogenic tumor is a rare benign odontogenic neoplasm which was first described by Pindborg in 1955 and accounts for less than 1％ of all odontogenic tumors. The tumor occurs primarily in the molar-premolar region of the mandible, and 52％ of cases are associated with an unerupted tooth. The clinical feature is most commonly a slow-growing painless swelling. The tumor may show considerable radiographic variation and usually characteristic histopathologic features. In this study, we report a case of the calcifying epithelial odontogenic tumor on the left mandibular body and ramus area in a 28-year-old male with a brief review of the concerned literatures.

Primary mesenteric liposarcoma is rare. It is difficult to make an accurate preoperative diagnosis of the myxoid type of liposarcoma by using imaging such as ultrasound or computed tomography (CT) due to the very small amount of fat that is located in the tumor. We report a case of primary myxoid liposarcoma of the mesentery which was difficult to differentiate from other solid mesenteric tumors with a myxoid component such as low grade fibromyxoid sarcoma, myxoid leiomyosarcoma or myxoma. Use of chemical shift magnetic resonance (MR) imaging to detect small fat components and its cystic appearance with solid components on the MR images can be useful to differentiate myxoid liposarcoma from the other mesenteric tumors with a myxoid component.
