Cystic craniopharyngioma: trans-sphenoidal surgery and intra-cystic apposition of "bleomycin wax".
No full textAbstract
BACKGROUND: The current therapeutic approach to craniopharyngioma is multidisciplinary. Sub-total removal, followed by adjuvant treatments, especially in large cystic tumours, is an accepted regime reported by many authors.
CASE REPORT: A young patient with an intra- and suprasellar cystic craniopharyngioma was operated on via a microsurgical trans-sphenoidal approach, achieving sub-total removal and bleomycin mixed with bone wax ("bleomycin wax") applied to the capsular remnant.
RESULTS: Pre-operative neurological and endocrinological deficit improved after surgery. There was no evidence of tumour recurrence after a follow-up period of 5.4 years.
CONCLUSIONS: The intra-operative use of "bleomycin-wax" should be limited to those patients in whom intra-operative CSF fistula does not occu
Ethmoidal encephalocele associated with cerebrospinal fluid fistula: indications and results of mini-invasive transnasal approach.
Full text linkAnterior skull base defects with encephalocele in adults are quite rare and can be a cause of spontaneous rhinoliquorrhea; however, cerebrospinal fluid (CSF) fistula can be not rarely misdiagnosed for several months or years. Five adult patients affected by ethmoidal encephalocele with CSF fistula were treated in our institute from 2006 through to 2011. Onset of clinical history was represented by rhinoliquorrhea, which was precociously recognized in only 1 patient; in the other 4, it was misdiagnosed for a period ranging from 11 months to 5 years. After clinical diagnosis of CSF fistula and after brain magnetic resonance imaging, ethmoidal encephalocele was evident in all patients; preoperative study was completed by spiral computed tomography scan, to clearly identify the skull base bone defect. All patients were operated on by transsphenoidal endonasal endoscope-assisted microsurgical approach through 1 nostril. The herniated brain was coagulated and removed, and reconstruction of cranial base was performed. Postoperative rhinoliquorrhea or other complications did not occur in any patient at short and late follow-up. All patients were discharged after a few days. Endonasal endoscope-assisted microsurgical approach was effective in exposing and repairing the ethmoidal bone defect; tridimensional vision and wide lateral and superior exposition of the operative field were possible in each patient, thanks to the use of microscope and angulated endoscope
Validity of percutaneous controlled radiofrequency thermocoagulation in the treatment of isolated third division trigeminal neuralgia
No full textBACKGROUND: Of 756 percutaneous controlled radiofrequency thermocoagulations of gasserian ganglion and/or retrogasserian rootlets for idiopathic trigeminal neuralgia or for trigeminal neuralgia in multiple sclerosis, the results in 158 patients who had isolated third division trigeminal neuralgia were reviewed.
METHODS: In 129 patients, percutaneous thermocoagulation was fluoroscopic guided, whereas in the last 29 the procedure was performed under CT control. In all cases, the goal was to achieve selective anesthesia limited to the third trigeminal division.
RESULTS: Complete pain relief was obtained immediately after the procedure in all patients and selective anesthesia in the third division was achieved in all of them, except for 2 patients in whom unwanted first and second division anesthesia/hypoesthesia also occurred. Other significant complications were transient sixth cranial nerve palsy in 1 patient and masseter muscle dysfunction, which improved during follow-up, in another one. The selected sensory impairment was well tolerated in all patients. During an average follow-up period of 8.8 years, recurrences occurred in 12 patients, together with a partial regression of the anesthesia: in 10 patients the procedure was repeated successfully. In 2 patients with multiple sclerosis, the procedure was repeated twice and 3 times, respectively.
CONCLUSIONS: Percutaneous controlled radiofrequency thermocoagulation is quite easy to perform under fluoroscopic or CT control, and it involves no mortality and very low morbidity; it is an immediately effective procedure and the rate of recurrence is low. Last, but not least, if the anesthesia is limited to the third division, no anesthesia dolorosa occurs and patients are very grateful
Conservative surgical approach and early postoperative radiotherapy in a patient with a huge cystic craniopharyngioma
Full text linkObjective: The treatment of huge craniopharyngiomas represents a therapeutic challenge for neurosurgeons. Some authors prefer to run the high risks of total removal at primary surgery, while others do not despise subtotal removal in accordance with a multidisciplinary treatment. Methods: We report the case of a 17-year-old girl who underwent subtotal removal (tumour remnant with maximum diameter of 2.5 cm) of a huge cystic craniopharyngioma by frontotemporal approach, followed by early external fractionated radiotherapy by linear accelerator. Serial magnetic resonance imaging during a follow-up period of 5 years showed a progressive marked reduction of the tumour remnant, accompanied by a complete recovery of visual deficits and an almost complete regression of diencephalic disturbances. Conclusions: Subtotal removal followed by early fractionated radiotherapy can be an effective treatment for huge craniopharyngiomas. Such a multidisciplinary treatment may favour tumour control and assure a satisfactory quality of life as well
