1/103. Spontaneous cerebrospinal fluid (CSF) rhinorrhoea in spongiform dysplasia of the cranium: an unusual presentation of neurofibromatosis.

    A 20-year-old woman with neurofibromatosis presented with CSF rhinorrhoea. Spongiform dysplasia of the cranium was found. The dysplastic bone contained CSF. The exact site of the CSF fistula into the calvarium and into the paranasal sinuses could not be detected on investigation but nasal packing of the ethmoid and sphenoid sinuses controlled the rhinorrhoea. The unique features of this case are presented along with a brief review of the literature.

2/103. Spontaneous cerebrospinal fluid leakage detected by magnetic resonance cisternography--case report.

    A 49-year-old male with no history of head trauma suffered cerebrospinal fluid (CSF) discharge from the left nostril for one month. Coronal computed tomography (CT) showed lateral extension of the sphenoid sinus on both sides and CSF collection on the left side. CT cisternography could not identify the site of CSF leakage. Heavily T2-weighted magnetic resonance (MR) imaging (MR cisternography) in the coronal plane clearly delineated a fistulous tract through the sphenoid bone into the sphenoid sinus. Patch graft with muscle fragment completely relieved the CSF rhinorrhea. Postoperative three-dimensional CT showed the two bone defects identified during surgery. Small bony dehiscences in the sphenoid bone and lateral extension of the sphenoid sinus predisposed the present patient to CSF fistula formation. MR cisternography in the coronal and sagittal planes is superior to CT scanning or CT cisternography for detection of the site of active CSF leakage.

3/103. Intracranial mucocele as a complication of endoscopic repair of cerebrospinal fluid rhinorrhea: case report.

    OBJECTIVE AND IMPORTANCE: Endoscopic repair of an anterior cranial fossa cerebrospinal fluid (CSF) fistula has gained widespread acceptance. We report a case of mucocele development at the site of an endoscopic CSF leak repair. CLINICAL PRESENTATION: A 46-year-old woman underwent functional endoscopic sinus surgery for nasal obstructive symptoms. The surgery was complicated by an intraoperative CSF leak from the posterior cribriform plate/anterior sphenoid, which was repaired immediately using bone and mucosa grafts. Two years postoperatively, a 13-mm anterior cranial base mass was found incidentally. This mass increased to 20 mm over the next year. INTERVENTION: The anterior cranial base mass was excised via a right frontal craniotomy and confirmed histologically to be a mucocele. CONCLUSION: Endoscopic repair of an anterior cranial base CSF fistula with mucosal grafts may lead to formation of a mucocele.

4/103. CSF rhinorrhoea following treatment with dopamine agonists for massive invasive prolactinomas.

    OBJECTIVE: The management of CSF rhinorrhoea following dopamine agonist (DA) treatment for invasive prolactinomas is difficult and there is no clear consensus for its treatment. Our objective was therefore to investigate the different treatments for this condition. DESIGN AND patients: We examined the case notes of five patients with invasive prolactinomas and CSF rhinorrhoea following DA treatment. The different ways in which this complication had been managed is detailed along with a review of the literature. RESULTS: Five patients aged 24-67 years (3 male) with massive invasive prolactinomas (serum prolactin 95000-500000 mU/l) eroding the skull base were treated with dopamine agonists (3 bromocriptine, 1 cabergoline and 1 both). CSF rhinorrhoea developed in all patients between 1 week and 4 months after commencing dopamine agonist treatment. In two patients (cases 1 and 4), CSF rhinorrhoea ceased within a few days of stopping bromocriptine but restarted when treatment was resumed. One of these (case 4), a 67-year-old woman had no further treatment and CSF leakage stopped completely. She died of unrelated medical problems 3 years later. In one patient staphylococcus aureus meningitis and pneumocephalus developed as a complication of CSF rhinorrhoea. Three patients had endoscopic nasal surgery to repair the fistula using muscle grafts, and to decompress the pituitary tumour, with success in two. One patient had intracranial surgery and dural repair, which was successful in sealing the leak. CONCLUSIONS: We suggest that surgery as soon as is feasible is the treatment of choice for the repair of a CSF leak following dopamine agonist treatment. An additional strategy is the withdrawal of dopamine agonist to allow tumour re-growth to stop the leak.

5/103. Intrasphenoidal encephalocele and spontaneous CSF rhinorrhoea.

    Intrasphenoidal encephalocele is a rare clinical entity. In the international literature only 16 cases have been reported up today, with female predominance. Clinically they manifest at middle and advanced ages (40-67 years), when spontaneous CSF rhinorrhoea or recurrent meningitis occurs. We present our case, a 46 years old female, who had CSF rhinorrhoea from the right vestibule for 10 months. The diagnosis was based on the history and the high-resolution brain and skull base CT-scanning in conjunction with opaque fluid injection in the subarachnoidal space through a lumbar puncture. She was successfully treated with an operation, through an endonasal trans-ethmoid microendoscopic approach, using the Draf and Stammberger technique. We discuss the pathogenesis of the intrasphenoidal encephalocele, the existence of small occult defects in the skull base, which cause, at the middle and advanced ages, CSF fistula with spontaneous CSF rhinorrhoea and/or recurrent meningitis. Finally we emphasize the advantages of the endonasal surgical approach for the treatment of this condition.

6/103. Bilateral cerebrospinal fluid rhinorrhoea.

    Cerebrospinal fluid (CSF) rhinorrhoea is leakage of fluid from the subarachnoid space to the frontal, sphenoidal or ethmoidal sinuses, and may occur spontaneously. The authors present the first reported case of bilateral spontaneous CSF rhinorrhoea. Bony defects on both sides of the cribriform plate were identified using endoscopic and radiological techniques, and the CSF fistula was closed endoscopically. The aetiology, diagnosis and contemporary surgical treatment of spontaneous CSF leaks is discussed. Endoscopic repair was successful in this case, and in view of the high success and low reported complication rates this surgical approach should be considered for treatment of spontaneous CSF rhinorrhoea.

7/103. Successful closure of recurrent traumatic csf rhinorrhea using the free rectus abdominis muscle flap.

    BACKGROUND: We present two patients in whom a free rectus abdominis muscle flap was used to close recurrent traumatic CSF rhinorrhea. CASE DESCRIPTION: CT scan of both patients showed frontal lobe atrophy and porencephaly after contusional hematoma. In the first patient, because the site of CSF leakage was not identified and the patient underwent three unsuccessful attempts to close the fistula using the fascia lata, we treated the patient by unifying all paranasal sinuses and by filling them with a free rectus abdominis muscle flap. In the second patient, CSF rhinorrhea recurred 6 years after closure of the fistula using the fascia lata. The patient underwent separation of a porencephalic cyst from the paranasal sinus and a free muscle flap was placed extradurally, because the CSF pulse pressure in the enlarged left anterior horn eroded the previously repaired fascia lata, resulting in the recurrence of CSF leakage. CONCLUSION: Although duraplasty is the primary procedure for repairing dural fistulas, the vascularized free muscle flap is an alternative method when the location of the fistula is not identified or the patient with recurrent CSF rhinorrhea has severe frontal lobe atrophy and porencephaly.

8/103. Transnasal endoscopic repair of cerebrospinal fluid rhinorrhoea.

    The complications associated with the employment of neurosurgical techniques for the management of cerebrospinal fluid rhinorrhoea has led to the development of extracranial approaches. The nasal endoscope can be used to improve visualisation of the site of the leak and to facilitate free graft or septal flap placement. This ensures a high rate of dural defect healing with minimal morbidity. This study describes four cases with CSF fistulas that were repaired endoscopically and the specific surgical techniques that were used. The authors believe that, in carefully selected cases, transnasal endoscopic management of CSF leaks can be the initial surgical treatment of choice.

9/103. Subtotal petrosectomy in the treatment of cerebrospinal fluid fistulae of the lateral skull base.

    Cerebrospinal fluid (CSF) fistulae almost invariably lead to meningitis, even in the absence of other clinically obvious sequelae of the fistula such as a CSF fluid leak. The only effective means of reducing the risk of meningitis is surgical closure of the fistula. If surgery is to be recommended to patients with CSF fistulae even if they are currently asymptomatic, the morbidity of the procedure must be a principal determinant of the chosen technique. Recovery after the extracranial approach to a CSF fistula is much more rapid than after an intracranial procedure. The extracranial route is also free of the long-term risk of epilepsy which accompanies a craniotomy. The principal disadvantage of the lateral extracranial approach, failure of treatment, has been largely eliminated following studies into the obliteration of simple bony cavities using free adipose grafts. This paper describes our use of the extracranial approach to closure of CSF fistulae of the lateral skull base.

10/103. Closure of recurrent frontal skull base defects with vascularized flaps -- a technical case report.

    Techniques for vascularized reconstruction of the anterior cranial fossa floor defects causing recurrent cerebrospinal fluid fistula are discussed in this report. The closure employs the use of local random- or axial-pattern vascularized flaps in simple cases. In complicated cases (for instance, status after repeated exploration) the tissue of the cranial base is severely compromised and shows low potential for healing. Non-vascularized grafts only add avital scars to the already present ones leading to recurrent fistulas. Free vascularized flaps show more mechanical strength and less scar contraction, resistance to infections and survive better in a compromised surrounding, thus leading to long term sealing in such cases. The technical issues of vascularized closure of defects of the frontal skull base are discussed in this report.
