1/182. Neurosurgical aspects of sphenoid sinus mucocele.

    The aetiological spectrum of sphenoid sinus mucocele includes congenital anomaly, trauma, infection, allergy and surgery of the sphenoid sinus. Enlargement of the mucocele, even with a short history, can result in progressive expansion of the sinus and extension of the lesion into the pituitary fossa, the suprasellar region, nasopharynx, orbits, clivus or ethmoid air cells. It is a benign cystic lesion with an excellent prognosis when treated appropriately. Generally, these lesions are managed by an ear, nose and throat surgeon, but when there is extension into the sellar and parasellar (especially suprasellar) regions they are managed by the neurological surgeon. sphenoid sinus mucocele should be considered in the differential diagnosis when there is suspicion of a cystic lesion in these regions. Three cases of large sphenoid sinus mucocele are presented, with discussion on their neurosurgical management and a review of the literature.

2/182. Reduction of nasal orbital fractures and simultaneous dacryocystorhinostomy.

    A technique for restoration of structure and function in naso-orbital fractures has been described. Three case reports demonstrate a few of the final results. The case reports also indicate that many of these fractures require late definitive surgery in spite of optimal surgical treatment immediately subsequent to injury.

3/182. Laparoscopic treatment of an appendiceal mucocele.

    Appendiceal mucocele is a rare entity with a nonspecific preoperative presentation and is diagnosed intraoperatively in a majority of cases. The emphasis lies in accurate pathologic diagnosis, as the final treatment can differ depending on the malignant potential. The case presented was correctly diagnosed preoperatively. Laparoscopic exploration was both diagnostic and therapeutic. This case demonstrates the utility and safety of laparoscopy in the treatment of appendiceal masses.

4/182. Concha bullosa pyocele--undiagnosed for 3 years.

    We report a rare case of post-traumatic concha bullosa pyocele in a diabetic teenager that has gone undiagnosed for 3 years. The clinical findings, radiological features and management are discussed. The literature is reviewed.

5/182. Clinical significance of magnetic resonance cholangiopancreatography for the diagnosis of cystic tumor of the pancreas compared with endoscopic retrograde cholangiopancreatography and computed tomography.

    BACKGROUND: Cystic tumor of the pancreas has been investigated by a variety of imaging techniques. Magnetic resonance cholangiopancreatography (MRCP) is being widely used as a non-invasive diagnostic modality for investigation of the biliary tree and pancreatic duct system. The purpose of this study was to compare MRCP images with those of endoscopic retrograde cholangiopancreatography (ERCP) and computed tomography (CT) in order to clarify the diagnostic efficacy of MRCP for cystic tumor of the pancreas. methods: We retrospectively studied 15 patients with cystic tumor of the pancreas that had been surgically resected and histopathologically confirmed. There were five cases of intraductal papillary adenocarcinoma, five of intraductal papillary adenoma, two of serous cyst adenoma, two of retention cyst associated with invasive ductal adenocarcinoma and one of solid cystic tumor. RESULTS: In all cases MRCP correctly identified the main pancreatic duct (MPD) and showed the entire cystic tumor and the communication between the tumor and the MPD. On the other hand, the detection rate by ERCP of the cystic tumor and the communication between the cystic tumor and the MPD was only 60%. Although the detection rates by CT for the septum and solid components inside the cystic tumor were 100 and 90.0%, respectively, those of MRCP for each were 58.3 and 20.0%. CONCLUSION: MRCP is capable of providing diagnostic information superior to ERCP for the diagnosis of cystic tumor of the pancreas. Although MRCP may provide complementary information about the whole lesion of interest, the characteristic internal features of cystic tumor of the pancrease should be carefully diagnosed in combination with CT.

6/182. mucocele of the anterior clinoid process: case report.

    OBJECTIVE AND IMPORTANCE: Of the primary intracranial mucoceles, those arising from the optic canal or anterior clinoid process are extremely rare. To our knowledge, only five cases have been reported. The pathogenesis of mucoceles at this unusual site is unclear, but the previously reported cases suggest that these mucoceles may originate from pneumatizing air cells in the anterior clinoid processes. CLINICAL PRESENTATION: A 43-year-old woman presented with diplopia. magnetic resonance imaging showed a small mass, compressing the optic nerve, in the medial portion of the left anterior clinoid process. The medial portion of the anterior clinoid process surrounding the mass was eroded and the bony margins of the mass were well corticated in computed tomographic scans. There was no direct connection between any paranasal sinus and the mass cavity, as assessed in imaging studies and intraoperatively confirmed. The pathological diagnosis after the operation indicated a mucocele. CONCLUSION: Considering the absence of air cells in the anterior clinoid processes, the mucocele in this case might have originated from ectopic mucinous tissue that appeared during the development of the optic canal, rather than from a pneumatizing air cell.

7/182. Isolated intracranial mucocele.

    Intracranial mucoceles have been previously reported as direct extradural extensions of mucoceles of the paranasal sinuses. We describe a patient with 2 silent mucoceles isolated within the parenchyma of the frontal lobe of the brain. The patient had undergone multiple previous intranasal polypectomy and ethmoidectomy procedures, and the unsuspected mucoceles were discovered on a computed tomographic scan obtained to evaluate recurrent rhinosinusitis symptoms. craniotomy was required for removal of the mucoceles.

8/182. mucocele-like formation leading to neurological symptoms in prolactin-secreting pituitary adenomas under dopamine agonist therapy.

    BACKGROUND: mucocele-like formation associated with pituitary adenomas, to the best of our knowledge, has been paid little attention. We report three adult male patients with a mucocele-like formation that developed behind the tumor and led to neurological symptoms in prolactin-secreting pituitary adenomas (prolactinomas) under dopamine agonist therapy. CLINICAL PRESENTATION: Three adult male patients with prolactinomas developed hyperprolactinemia and new neurological symptoms during dopamine agonist treatment. In each case, the pathogenesis of these symptoms was due in part to a mass enlargement with development of a mucocele-like formation behind a prolactinoma. In our patients, a prolactinoma with a suprasellar extension originally filled the sphenoid sinus. When dopamine agonist therapy became ineffective, new symptoms, such as progressive visual impairment other than typical hemianopsia or headache, developed and mass enlargement was found on MRI. MRI demonstrated two different components: an enhancing prolactinoma and a nonenhancing mucocele-like formation behind the tumor. Two patients had compression of the optic nerves by a mass. Transnasal removal of mucoceles and adenomas led to resolution of the neurological symptoms. CONCLUSION: Early suspicion of a mucocele-like formation under dopamine agonist therapy for prolactinomas is important in order to avoid a delay in surgery, because a change in medical treatment will be ineffective.

9/182. Endoscopic marsupialization of bilateral lacrimal sac mucoceles with nasolacrimal duct cysts.

    A lacrimal sac mucocele is an uncommon disease usually treated by ophthalmologists. In rare cases, it is sometimes associated with a nasolacrimal duct cyst presenting as an intranasal cystic mass, which needs the involvement of an otolaryngologist in diagnosis and management. Two cases of lacrimal sac mucoceles with nasolacrimal duct cysts are presented with a brief literature review. Both cases presented with intranasal cystic masses that caused nasal obstruction and were cured with endoscopic marsupialization of the cysts.

10/182. Double gall bladder with two disease processes.

    A double gall bladder is a rare congenital anomaly which is usually diagnosed by preoperative ultrasonography. Either one, or both lobes, of the double gall bladder, may be diseased. We report a patient in whom the two lobes were affected by different disease processes, namely, cholesterosis, and cholelithiasis with mucocele.
