On the occasion of one case of appendiceal mucocele, the authors studied on etiology, classification, clinical signs, diagnosis and treatment of this disease. Results: Appendiceal mucocele is a rare injury form of appendix, it stretches out and full of mucosity. It might be a benign or malignant injury. Clinical symptoms are not typical therefore it is difficult to diagnose before operating; most of the cases were discovered by accident. Recently, they can preoperative diagnose by ultrasound and CT scan. If the injury is benign, the appendix is removed simply, even through endoscopy, but if the injury is doubt to be malignant, it is necessary to resect the right colon. Although it is a malignant injury, the prognosis is still good as a colon cancer.

PURPOSE: To evaluate the usefulness of CT features of appendiceal mucocele in the diagnosis and evaluation of complications. MATERIALS AND METHODS: We retrospectively reviewed CT findings and compared with operative findings in 7 cases of pathologically proven appendiceal mucocele. CT findings such as location and extent of the lesion, Issue density, thickness or calcification of the wall, presence of adjacent inflammatory infiltration, and visualization of normal vermiform appendix were analyzed. RESULTS: Appendiceal mucocele was found as homogeneous low density cystic mass adjacent to the cecum, which has no surrounding inflammatory infiltration except in one case of perforation and one case of intussusception. Mean CT number measured in 4 cases was 21 Hounsfield unit. Thin curvilinear calcifications were noted along the cystic wall in 2 cases. Normal vermiform appendix couldn't be demonstrated in all cases. CONCLUSION: Appendiceal mucocele is characterized by homogeneously low density and thin walled cystic tumor adjacent to cecum without surrounding inflammatory infiltration, and absence of normal vermiform appendix on CT. Therefore, CT is valuable in preventing operative complications of appendiceal mucocele.

Mucoceles are relatively common cystic lesions of the paranasal sinuses. However, mucocele of the nasal septum is extremely rare. We report a case of a mucocele present in this unusual location. Mucocele of the nasal septum should be considered in the differential diagnosis of a mass of the nasal septum and/or median canthal region. Nasal septal mucocele can be effectively treated with endoscopic marsupialization or complete excision.

The authors analyse the ultrasonographic findings of 10 cases of appendiceal mucocele retrospectively. In atotal of 10 cases, 6 cases showed only cystic masses with posterior reinforcement. The remaining 4 cases showedinternal echoes in the cystic masses. Differential diagnosis of mucocele from periappendiceal abscess is notpossible in ultrasound. The possibility of mucocele shold be considered if cystic mass in right lower quadrantabdomen is observed in ultrasound.

A mucocele of the sphenoid sinus is relatively rare, and it has nonspecific clinical features. Hence, it is hard to diagnose it with the history of the illness alone. However, if the sphenoid mucocele is not detected and treated in early stage, its sequalae could be very serious or permanent, such as intracranial complication or blindness. Recently, the authors experienced a case of a sphenoid mucocele with unilateral visual disturbance for a period of one year. The patient underwent endoscopic sinus surgery-marsupialization successfully, but remnant visual disturbance as a sequalae did not fully recover. Thus high index of suspicion, prompt diagnosis using imaging studies, and urgent surgical intervention are crucial for promising of complete recovery from the disease.

The appendiceal mucocele is a rare disease and very difficult to get the diagnosis preoperatively because of the rartity of classical symptoms. With progress in diagnostic procedures such as colonofiberscopy, preoperative diagnosis of appendiceal mucocele has become possible. We experienced a case of appendiceal mucocele in 50 years old male who was admitted due to vague RLQ discomfort, and was diagnosed by colonofiberscopy and surgical specimen obtained by right hemicolectomy. So we present this case with a review of literatures.

Frontal sinus outflow tract (FSOT) injury may occur in cases of frontal sinus fractures and nasoethmoid orbital fractures. Since the FSOT is lined with mucosa that is responsible for the path from the frontal sinus to the nasal cavity, an untreated injury may lead to complications such as mucocele formation or chronic frontal sinusitis. Therefore, evaluation of FSOT is of clinical significance, with FSOT being diagnosed mostly by computed tomography or intraoperative dye. Several options are available to surgeons when treating FSOT injury, and they need to be familiar with these options to take the proper treatment measures in order to follow the treatment principle for FSOT, which is a safe sinus, and to reduce complications. This paper aimed to examine the surrounding anatomy, diagnosis, and treatment of FSOT.

PURPOSE: We report two cases of mucocele formation after medial orbital wall fracture repair with an alloplastic implant. CASE SUMMARY: A 61-year-old man with a history of a medial orbital wall fracture repaired with an alloplastic implant five years earlier presented with a several-month history of left proptosis without diplopia, pain, or lid edema. A 55-year-old man with a history of a medial orbital wall fracture repaired with an alloplastic implant seven years prior, presented with a five.year history of left proptosis with diplopia. Computed tomography (CT) scans revealed a large cyst on the orbital medial wall, which surrounded the alloplastic implant and had no definite enhancement. The patients underwent orbital surgery to remove both the cyst and implant. Histologic examination of the cyst revealed a capsule lined with ciliated pseudostratified columnar epithelium. Both patients had an uncomplicated postoperative course with resolution of the proptosis. CONCLUSIONS: For cases that present with late proptosis after orbital fracture repair, mucocele formation should be included in the differential diagnosis.

Appendiceal mucocele is a cystic dilatation of the appendiceal lumen with mucus, which may be caused by either benign or malignant diseases. In this report, five cases of appendiceal mucocele are reported, three of which had a preoperative diagnosis of mucocele, whereas the others were found incidentally during the operation under the diagnosis of intussusception and periappendiceal abscess. All five patients underwent surgical resections, including one ileocecal resection and four right hemicolectomies. Histopathology revealed a mucinous cystadenoma in four cases, and a mucinous cystadenocarcinoma in one. There was no disease-related death during 18 months of follow-up.
