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,...

Ethmoid sinus mucoceles are benign, expansile and cyst-like lesions, when sufficiently large, may causing compression of the optic nerve and nearby structures. We report an extremely rare case of ethmoid sinus mucocele causing orbital apex syndrome. A 59-year-old female presented with over one month history of left-side headache that worsened with left-side ophthalmodynia for six days, accompan...

Mucocele is a benign lesion characterized by an extravasation or retention of mucous in submucosal tissue from minor salivary glands. Mucoceles are known to occur most commonly on the lower lip, followed by the floor of mouth and buccal mucosa being the next most frequent sites. Trauma and lip biting habits are the main cause for these types of lesions. Mucocele is a common oral mucosal lesion ...

BACKGROUND Mucinous cystadenocarcinoma is the second most common etiology of appendiceal mucocele. We report a relatively rare case of a giant appendiceal mucocele caused by mucinous cystadenocarcinoma, which occupied the entire abdomen of an adult woman. CASE PRESENTATION A 63-year-old woman presented with a chief complaint of abdominal distention. Imaging studies showed a giant cystic mass ...

We present the first ever report on a colonic mucocele observed at the distal stump of a transverse loop colostomy caused by neoplasia. A 37-year-old female consulted us because of abdominal pain and vomiting caused by cystic lesions in the upper left abdominal quadrant. A preoperative checkup revealed no sign of neoplastic lesions; however, tumor resection was performed because of the symptoms...

We found a case of salivary mucocele that originated in the minor salivary gland (palatine gland) of the soft palate in a dog. At first admission, the soft palate swelled remarkably. Computed tomography (CT) revealed cystic radiolucency inside a large quantity of liquid in the soft palate, and most of the airway was occupied. Marsupialization was performed, but since a recurrence was observed o...

An 8-year-old, neutered male Yorkshire Terrier dog presented with left ventromedial canthus swelling over a one-month period, refractory to pharmacological therapy. There was no history of trauma. On ultrasonography, the lesion had cystic character filled anechoic fluid and hyperechoic sedimenting debris. The computed tomography (CT) CT-dacryocystography showed protruding from lacrimal sac foss...

Background: Mucocele of the appendix is a clinical term for a pseudocyst that is associated with mucus extravasation into the surrounding medium. This may be the result of neoplastic causes. Case Presentation: Two cases of the mucocele of the appendix at Golestan hospital of Ahwaz were found. The first case was a 70 years lady who complained of the pain in lower part of her abdomen since 1 yea...

Salivary mucocele is a common lesion derived from minor salivary glands with various surgical or non-surgical treatment modalities. To evaluate the effect of a highly potent corticosteroid (dexamethasone) in the management of salivary mucocele, we performed intralesional injection of dexamethasone in nine patients with labial mucocele. Complete healing of lesions observed in seven of nine patie...
