Onodi cells have been defined as posterior ethmoid cells that have pneumatized laterally and superiorly to the sphenoid sinus. They are often close to the optic nerve or the internal carotid artery. A patient complained of a sudden decrease in left eye visual acuity and left eye pain due to formation of a primary mucocele in an Onodi cell. A coronal computed tomography scan and magnetic resonan...

Appendiceal mucocele (AM) is an obstructive dilatation of the appendix by the intraluminal accumulation of mucoid material which has been recognized by Rokitansky in 1842 and was formally defined by Feren in 1876 [1]. Its clinical presentation can vary from the patient being asymptomatic in 50% cases of the patient exhibiting symptoms that mimic those in acute appendicitis or appendicular mass....

OBJECTIVES We present the clinical and radiological features, treatment protocols, and medium-long-term results of our patients following surgery for paranasal sinus mucocele, along with a review of the relevant literature. MATERIALS AND METHODS A total of 18 patients (11 women and 7 men) who underwent surgery for paranasal sinus mucocele at Kocaeli University Faculty of Medicine, Department ...

This study evaluated the efficacy of the modified endoscopic Lothrop procedure (MELP) for complicated frontal mucoceles and endoscopic marsupialization for other paranasal sinus mucoceles. It was a retrospective, consecutive case review of sinus mucoceles treated endoscopically by a single surgeon over a four-year period (1998-2002). There were 41 mucoceles in 28 patients, including 24 frontal,...

Introduction: The mucocele is one of the most common benign soft tissue masses that occur in the oral cavity. Mucoceles (mucus and coele cavity), by definition, are cavities filled with mucus. Two types of mucoceles can appear – extravasation type and retention type. Diagnosis is mostly based on clinical findings. The common location of the extravasation mucocele is the lower lip and the treatm...

Frontal mucocele is not commonly masked as upper lid abscess.A 72-year-old Chinese man with underlying hyperthyroidism complained of left upper eyelid swelling of 6 months duration. The swelling had persisted and worsen when intravenous antibiotic was changed oral type. Visual acuity on presentation was hand motion and reverse relative afferent pupillary defect was present. Because the swelling...

We report a case of appendiceal mucinous cystadenoma that was successfully diagnosed preoperatively and treated by laparoscopic resection. We could find volcano sign on colonoscopy and cystic lesion without any nodules at the appendix on computed tomography (CT). Without any malignant factors in preoperative examinations, we performed laparoscopic appendectomy including the cecal wall. We could...

HIV-salivary gland associated disease is a well accepted concept in the HIV-related literature. Parotid swellings, especially in its cystic benign lymphoepithelial form, have been largely reported. Oral mucoceles (ranulas) were also associated with HIV in some publications. The exact nature of this link between mucoceles and HIV is still to be clarified. The mainstream treatment of most of paro...

A 66 year old Indian gentleman presented with a 3 days history of headache and gradual progressive loss of vision in his eft eye, ophthalmological assessment showed no light perception in his left eye with papilledema and afferent papillary defect. Computed tomography (CT) and Magnetic Resonance Imaging (MRI) were done and showed an expanding lesion in the left anterior clinoid process encroach...

Mucocele of the appendix due to mucinous cystadenoma is a rare clinical finding. Approximately half of the patients are asymptomatic. It's defined as the dilatation of the appendiceal lumen due to abnormal accumulation of mucus in to it. The pseudomyxoma peritonei, as a result of rupture of the appendix, is the most dangerous complication. We present two case reports of patients that were prese...
