A 10-year-old girl with no nasal or respiratory symptoms developed a headache lasting a few hours. The next day she became totally blind in the right eye and over 5 days vision in the left eye deteriorated to bare light perception. The diagnosis of a sphenoid sinus mucocele was made radiologically and drainage via an endonasal sphenoidectomy produced 12 ml of brownish fluid. Endoscopic biopsy o...

Surgical exclusion of the thoracic esophagus can result in the accumulation of secretions and dilatation of the esophageal remnant, a clinical picture known as esophageal mucocele. Although it is usually asymptomatic, if it increases in size it can produce a variety of compressive symptoms such as coughing, chest pain and respiratory distress. We present two cases of symptomatic mucocele after ...

Appendicular mucoceles are rare clinical findings characterized by dilation and distention of the appendicular lumen by the accumulation of mucus. Their discovery is often incidental from abdominal imaging or more commonly as a secondary surgical finding. In this case study we report the first known recorded case of a cadaveric mucocele appendix discovered during routine dissection of the gastr...

A 31-year-old lady presented to the otorhinolaryngology clinic complaining of right exophtalmus. Imaging studies revealed a right frontal sinus mass, suggestive of a mucocele, and fronto-ethmoidal ground glass opacification. In the operating room, the frontal sinuses were exposed through an osteoplastic flap, and connected to the nasal cavity through a Lothrop-like drainage pathway. The patholo...

Mucinous cystadenoma of the appendix is a type of appendiceal mucocele and a rather rare condition usually found incidentally in the course of other abdominal surgery. A previous evaluation of 73 appendiceal mucoceles showed that this disease was often associated with adenocarcinoma and other epithelial atypia. This observation suggested that patients with mucinous cystadenoma of the appendix a...

Mucocele of the appendix is a descriptive term for an abnormal mucous accumulation distending the appendiceal lumen. Pseudomyxoma peritonei is characterized by mucinous ascites and implants throughout the abdominal cavity. Thirty-four cases of appendiceal mucocele and seven cases of pseudomyxoma peritonei of appendiceal origin on file at the Armed Forces Institute of Pathology were reviewed for...

Mucoceles of the appendix are very rare lesions and are occasionally associated with pseudomyxoma peritonei, a gelatinous ascites that arises from intraperitoneal rupture or degeneration of the mucocele. Rupture of a retroperitoneal mucocele of the appendix is extremely rare; pseudomyxoma extraperitonei has been previously reported in only five patients. We report a new case of pseudomyxoma ext...
