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.

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.

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.

Mucocele arised at the vermiform appendix is uncommon, either benign or malignancy and their clinical presentation is not specific. The preoperative diagnosis is rare,1 and their diagnosis is an incidental event. Mucocele seems to be developed due to chronic obstruction of the lumen of the appendix. Higa and Cowerkers2 classified 73 cases of "mucocele" into three clinicopathologic entities; focal or diffuse mucosal hyperplasia, mucinous cystadenoma, mucinous cystadenocarcinoma. Appendiceal mucoceles are rare lesions of the appendix, characterized by a gross enlargement of the appendix from accumulation of mucoid substance within the lumen. It is encountered in only 0.1-0.4% of all appendectomies with a female predominance and an average age at the time of diagnosis over 50 years. A case of appendiceal mucocle found during total hysterectomy is presented with a brief review of the literatures.

Acute optic neuropathy occurs commonly as a result of ischemia and inflammation, but paranasal sinus disease without infection is generally dismissed. We report a rare case of acute optic neuropathy caused by compression of a mucocele in an Onodi cell, which is an uncommon anatomical variation of the ethmoid sinus. The mucocele was confirmed by imaging and endoscopic sinus surgery. An Onodi-cell lesion should be considered in the differential diagnosis of acute optic neuropathy.

Mucocele of the appendix is a rare disease entity which is infrequently diagnosed prior to a laparotomy. With progress in diagnostic procedures, such as the use of ultrasonography, computed tomography, and colonoscopy, preoperative diagnosis of the appendiceal mucocele has become possible. The case that we have experienced involves an eighty five-year old male. He was admitted with bowel obstruction symptoms such as severe abdominal pain, tenderness, and increased bowel sound sounds. He was diagnosed as having appendiceal mucocele by an abdominal CT and colonoscopy, He was operated on and the surgical specimen revealed appendicea] mucocele.
