21/494. Bronchial atresia with transient spontaneous disappearance of a mucocele.

    We report the transient spontaneous disappearance of a mucocele due to bronchial atresia. Two years before presentation, a chest radiograph showed a hyperlucent right upper lung and a mucocele near the right hilum. A chest radiograph taken 1 year later showed that the mucocele had disappeared leaving an ovoid outline of a dilated bronchus. A chest radiograph obtained 3 months before presentation showed that the mucocele was present again. Atresia of the B3b bronchus of the right upper lobe was noted on thoracotomy. The "disappearance" of the mucocele probably was due to the clearance of mucoid material through collateral airways. ( info)

22/494. submandibular gland mucocele: diagnosis and management.

    Mucoceles originating from the submandibular gland are extremely rare. A review of the English literature resulted in identification of only 5 such cases. We have diagnosed and treated 2 submandibular mucoceles. Both lesions were removed in continuity with the submandibular and sublingual glands. No complications and no recurrences have occurred to date. The diagnosis of these lesions is complicated because of the lack of specific clinical diagnostic criteria and the similarity between submandibular mucoceles and plunging or cervical ranulas. Computerized tomography and specifically the presence of a so-called "tail" sign is pathognomonic for plunging ranula. This sign is absent in mucoceles originating in the submandibular glands. The treatment strategies vary as well. A diagnostic algorithm and a surgical rationale for treatment of submandibular mucoceles are presented. ( info)

23/494. Management and complications of congenital dacryocele with concurrent intranasal mucocele.

    INTRODUCTION: The association of dacryocele and intranasal mucocele has been previously reported. Its incidence and optimal treatment are unknown. patients and methods: A retrospective review of 22 patients with 30 dacryoceles was performed to determine the mean age at presentation, sex distribution, and prevalence of associated intranasal mucocele, associated dacryocystitis, and respiratory distress. The components of the examination, ancillary tests, treatment modalities, and treatment outcomes were then summarized. RESULTS: Unilateral dacryoceles were seen in 16 (73%) of the infants, and bilateral dacryoceles were seen in 6 (27%) of the infants. Four (25%) of the 16 patients who initially had unilateral dacryoceles later developed bilateral dacryoceles. dacryocystitis, preseptal cellulitis, or both were present on presentation or developed in 18 (60%) of 30 dacryoceles. Nasal endoscopy was performed on 13 (59%) of 22 patients. Nasal examination with nasal speculum and headlight was performed on 7 patients (32%). A concurrent intranasal mucocele was diagnosed in 23 (77%) of 30 dacryoceles. Respiratory distress arose in 5 (71%) of 7 patients with bilateral intranasal mucoceles and in 2 (22%) of 9 patients with a unilateral intranasal mucocele. Thirty-four procedures were performed. Seven dacryoceles (21%) were treated with nasolacrimal duct probing under topical anesthesia. Another one (3%) was treated with needle aspiration with later definitive therapy. All other procedures were managed under general anesthesia. These included 2 nasolacrimal duct probings (6%), 2 probings with silicone tube placement (6%), 10 probings with intranasal mucocele marsupialization and silicone tube placement (29%), and 12 probings with marsupialization alone (35%). Two (29%) of the 7 probings performed under topical anesthesia failed, whereas all other procedures were successful. One dacryocele spontaneously resolved. CONCLUSIONS: Congenital dacryoceles are commonly associated with intranasal mucoceles, dacryocystitis, and preseptal cellulitis. Respiratory distress is common in bilateral cases. Bilateral nasolacrimal duct probing should be considered in unilateral cases because of the high incidence of occult contralateral involvement. ( info)

24/494. Sphenoidal sinus mucocele after transsphenoidal surgery for acromegaly.

    This report concerns one case of a sphenoid sinus mucocele occurring 17 years after transsphenoidal surgery for acromegaly. In 1979, a 51-year-old man was successfully operated by the transnasal transsphenoidal approach for a growth hormone (GH) adenoma 1 cm in diameter. In 1996, the patient was hospitalized for headaches and diplopia. He presented a loss of right visual acuity with paralysis of the right oculomotor nerve. The basal GH level was normal with a satisfactory decrease after oral glucose ingestion. Pituitary sellar radiography showed a disappearance of the posterior clinoid while magnetic resonance imaging revealed the existence of a bilocular, circular, homogeneous lesion of the sphenoid sinus 3 cm in diameter with a posterior and lateral extension. The diagnosis of mucocele was confirmed by surgical treatment, allowing drainage of the mucocele through a transsphenoidal approach. The drained material was composed of sinus epithelium containing many polynuclear and resorptive cells. Postoperatively, the symptoms decreased dramatically, leading to full recovery of visual function and disappearance of the headaches. Apart from the tumor recurrence, the mucocele of the sphenoid sinus can be evoked as a possible long term complication of transsphenoidal surgery for pituitary adenoma. ( info)

25/494. Mucocoeles of the maxillary sinus.

    Mucocoeles of the paranasal sinuses most commonly occur in the frontal or anterior ethmoidal sinuses. We report two rare cases of mucocoele of the maxillary sinus and describe the presentation, investigations and treatment. A review of the literature on this rare clinical entity is included, with specific reference to diagnostic imaging to distinguish mucocoeles from neoplastic sinus disease. ( info)

26/494. Maxillofacial hydatid cysts.

    We report 2 cases of hydatid cysts occurring in the submandibular gland and buccal submucosa, respectively. Our first case occurred in the submandibular salivary gland of a 20-year-old woman and the second involved the buccal submucosa of a 6-year-old boy. Both diagnoses were made after the excision of the lesions. Both patients were evaluated after surgery, and both were followed up, but no other organs were involved. ( info)

27/494. Nasal non-Hodgkin's lymphoma causing mucocele of the maxillary antrum.

    The authors report a case of an antral mucocele secondary to obstruction of the antral ostium by a non-Hodgkin's lymphoma. Antral mucoceles are rare, and this is the first report of one such caused by a nasal lymphoma. ( info)

28/494. A case of optic neuropathy treated by percutaneous trans-coronary angiography.

    There are many risk factors involved in the development of ischemic optic neuropathy such as diabetes mellitus, hypertension, arteriosclerosis, and vascular incompetence. Therefore, the treatment of ischemic optic neuropathy should not be solely based on proper diagnosis but should also involve a thorough and systemic investigation to identify those multifactorial possibilities, which may contribute to the pathogenesis of the disease. We report upon a patient who developed non-arteritic ischemic optic neuropathy following treatment of a sphenoethmoid mucocele, which lead to recovered vision and a satisfactory improvement of visual field defects, after percutaneous trans-coronary angiography with stent insertion of the coronary arteries.

29/494. A giant intracranial mucocele associated with an orbitoethmoidal osteoma. Case report.

    The authors present a rare case of a giant intracranial mucocele associated with an orbitoethmoidal osteoma in a patient suffering from a generalized convulsive disorder. The broad pedicle of the osteoma had penetrated the cribriform plate and extended intracranially to form a nodular mass in the olfactory groove. The intracranial portion of the osteoma was surrounded by a mucocele. Both the cyst wall and multilayered intracystic septations of the mucocele were indented by layers of the osteoma. Although the extracranial portion adhered to the mucosa of the ethmoidal sinus, there were no signs of sinus obstruction. No direct communication other than the osteoma was identified between the mucocele and the ethmoidal mucosa. The large cerebral defect, which the mucocele occupied, communicated directly with the lateral ventricle without any intervening membranous structures. A frontal craniotomy is recommended for exposure of the lesion and plastic repair of the dural defect. ( info)

30/494. Compartmentalized maxillary sinus mucocele.

    A rare case of compartmentalized maxillary sinus mucocele 12 years after a Caldwell-Luc operation is reported. The two separate mucoceles were drained intranasally by endoscopic sinus surgery. The clinical features of this mucocele are presented and the incidence, presentation and theories on formation of post-operative mucoceles are reviewed. ( info)
