Purpose: To report the case of a patient with adrenocorticotropic hormone (ACTH)-producing pituitary adenoma who developed a mental disorder after initial surgery that kept him from undergoing scheduled follow-up visits and who ultimately had a giant recurrent tumor that resulted in blindness. Case Report: A 37-year-old male presented with the primary complaint of decreased visual acuity (VA) in both eyes and visual field defects. Visual field examination revealed bitemporal hemianopia. Magnetic resonance imaging (MRI) showed a pituitary tumor of approximately 4 cm in diameter extending from the intrasellar region to the sphenoid sinus and the suprasellar region. Transnasal transsphenoidal surgery was performed. Immunostaining of tumor tissue collected intraoperatively showed ACTH-positive cells, thus leading to the diagnosis of ACTH-producing pituitary adenoma. Postoperatively, the patient reportedly developed mental disorder that possibly interfered with scheduled appointments or continuous follow-up visits for many years, so we had no postoperative data about the vision/visual filed. Seven years later, he presented with markedly decreased VA (i.e., no light perception) in both eyes. Fundus examination showed bilateral marked optic disc atrophy. MRI showed a larger than 8-cm diameter giant recurrent pituitary adenoma in the suprasellar region, for which craniotomy was performed for partial tumor resection. Preoperatively, his blood cortisol level was low, and the lesion was deemed a nonfunctioning pituitary adenoma. Postoperatively, no significant complications occurred, yet his VA was no light perception OD and light perception OS. Conclusions: Clinicians should be aware that patients with ACTH-producing pituitary adenomas may develop a mental disorder following surgery and possibly be unable to undergo scheduled follow-up, thus illustrating the importance of establishing an adequate patient follow-up system.

Abstract BACKGROUND Compressive optic neuropathy is the most common indication for transsphenoidal surgery for pituitary adenomas. Optical coherence tomography (OCT) is a useful visual assessment tool for predicting postoperative visual field recovery. OBJECTIVE To analyze visual parameters and their association based on long-term follow-up. METHODS Only pituitary adenoma patients with abnormal visual field defects were selected. A total of 188 eyes from 113 patients assessed by visual field index (VFI) and 262 eyes from 155 patients assessed by mean deviation (MD) were enrolled in this study. Postoperative VFI, MD, and retinal nerve fiber layer (RNFL) thickness were evaluated and followed up. After classifying the patients into normal (>5%) and thin (<5%) RNFL groups, we investigated whether preoperative RNFL could predict visual field outcomes. We also observed how RNFL changes after surgery on a long-term basis. RESULTS Both preoperative VFI and MD had a linear proportional relationship with preoperative RNFL thickness. Sustained improvement of the visual field was observed after surgery in both groups, and the degree of improvement over time in each group was similar. RNFL thickness continued to decrease until 36 mo after surgery (80.2 ± 13.3 μm to 66.6 ± 11.9 μm) while visual field continued to improve (VFI, 61.8 ± 24.5 to 84.3 ± 15.4; MD, −12.9 ± 7.3 dB to −6.3 ± 5.9 dB). CONCLUSION Patients with thin preoperative RNFL may experience visual recovery similar to those with normal preoperative RNFL; however, the probability of normalized visual fields was not comparable. RNFL thickness showed a strong correlation with preoperative visual field defect. Long-term follow-up observation revealed a discrepancy between anatomic and functional recovery.

Transsphenoidal Resection

BACKGROUNDAlthough craniopharyngioma and pituitary adenoma are common tumors of the sellar or suprasellar region, the development of papillary craniopharyngioma in the same sellar region after resection of a nonfunctioning pituitary adenoma has not been reported.OBSERVATIONSHere the authors report the first case of craniopharyngioma that developed long after resection of a pituitary adenoma. A 66-year-old male patient underwent endoscopic transsphenoidal resection for a large sellar mass, which histopathologically confirmed the diagnosis of a pituitary adenoma. He had an excellent recovery after surgery. For several years, he had no clinical or imaging evidence of tumor recurrence and then was lost to follow-up. Seven years after the initial surgery, the patient returned with a one-month history of visual field defects, and imaging confirmed a heterogeneous, cystic suprasellar mass. Endoscopic transsphenoidal resection of the tumor was performed, and histological examination showed it to be a papillary craniopharyngioma.LESSONSNeurosurgeons should be aware that after pituitary adenoma resection, a recurrent mass could be a craniopharyngioma, with implications for very different management recommendations.

Background: Pituitary adenoma, which accounts for 17.4% of all brain tumors, is the third most frequently diagnosed brain tumor, following intracranial glioma and meningioma. The visual disturbance in pituitary adenoma ranged from blurring of vision with or without headache to total loss of vision. In patients with visual field defects, bitemporal hemianopia was the commonest visual field defect. Early improvement of visual function is one of the major indication surgery. Objective: The purpose of this study was to comparison between the pre and post-operative visual parameters and to find out the value in assessment of the prognosis of early postoperative visual function and also to find out the factor which influence the early post-operative visual outcome. Methods: A prospective study was done from September 2010 to April 2012 in the department of neurosurgery, Bangabandhu Sheikh Mujib Medical University, 30 cases of pituitary adenoma had been included in this study of those who were presented with visual symptoms. Visual assessment was done before the operation and outcome was analyzed at discharged from hospital. Results: Within 60 eyes, 13 (43.3%) patients presented with blindness of one or both eyes. 10 (33.3%) presented with uniocular and 3 (10.0%) presented with binocular blindness. Duration of the symptoms ranged from 2 months to 48 months. Patients underwent either transcranial or transsphenoidal tumor decompression. At discharge out of 30 patients, 23 (76.7%) showed improvement, 2 (6.6%) patients were deteriorated post-operatively. P value was <0.001, in z ‘test’, Z=91.5, which was highly significant. Post-operative visual status was analyzed with age, sex, duration of symptoms, suprasellar extension, and methods of surgery and extent of tumor resection to find out that any other factor influenced the visual outcome. In bivariate analysis it was shown that only duration of the symptoms only other factor that influenced the visual outcome (statistically significant, p value 0.017). Conclusion: With this study it was statistically proved that pre-operative visual status is the main factor for improvement of early post-operative visual outcome in pituitary adenoma and duration of symptoms had also influence the early post-operative visual outcome. Duration less than 12 months had a favorable outcome. DOI: http://dx.doi.org/10.3329/bjn.v28i2.17182 Bangladesh Journal of Neuroscience 2012; Vol. 28 (2): 108-115

Abstract BACKGROUND As the outcome of pediatric brain tumors improves, late recurrence and radiation-induced tumor cases are more likely to occur, and the number of cases requiring re-irradiation is expected to increase. Here we report two cases performed intracranial re-irradiation after radiotherapy for pediatric brain tumors. CASE 1: 21-year-old male. He was diagnosed with craniopharyngioma at eight years old and underwent a tumor resection. At 10 years old, the local recurrence of suprasellar region was treated with 50.4 Gy/28 fr of stereotactic radiotherapy (SRT). After that, other recurrent lesions appeared in the left cerebellopontine angle, and he received surgery three times. The tumor was gross totally resected and re-irradiation with 40 Gy/20 fr of SRT was performed. We have found no recurrence or late effects during the one year follow-up. CASE 2: 15-year-old female. At three years old, she received 18 Gy/10 fr of craniospinal irradiation and 36 Gy/20 fr of boost to the posterior fossa as postoperative irradiation for anaplastic ependymoma and cured. However, a anaplastic meningioma appeared on the left side of the skull base at the age of 15, and 50 Gy/25 fr of postoperative intensity-modulated radiation therapy was performed. Two years later, another meningioma developed in the right cerebellar tent, and 54 Gy/27 fr of SRT was performed. Thirty-three months after re-irradiation, MRI showed a slight increase of the lesion, but no late toxicities are observed. CONCLUSION The follow-up periods are short, however intracranial re-irradiation after radiotherapy for pediatric brain tumors were feasible and effective.

Abstract Background While bitemporal visual field defects are characteristic in pituitary adenoma cases, it is rare to have complete bitemporal hemianopsia that is symmetrical in both eyes and has absolute scotoma throughout both temporal hemifields. Although several researches have investigated asymmetric visual field defects in patients with pituitary adenoma, no precise investigation with statistical analysis regarding the inter-eye and intra-eye symmetry of visual field defects has yet been reported. In this study, we conducted quantitative analysis to explore the asymmetric properties of visual field defects in pituitary adenoma patients. Methods Preoperative Humphrey 30-2 perimetry results were reviewed retrospectively using the charts of 28 pituitary adenoma patients who underwent surgery. Inter-eye light sensitivity comparisons of the temporal and nasal hemifields between the left and right eyes were conducted in each patient to study left-right asymmetry. Upper-lower asymmetry was investigated by comparing the frequency of severe scotoma (light sensitivity 5 dB or less) in the upper and lower visual field quadrants in the temporal and nasal hemifields. Results Left-right asymmetry was demonstrated in 61% of cases in the temporal hemifield and in 57% of cases in the nasal hemifield. Severe scotoma test points were investigated in the worse eye of each patient and were more frequent in the superotemporal quadrant of the visual field compared with the inferotemporal quadrant (P = 0.00029) and in the inferonasal quadrant compared to the superonasal quadrant (P = 0.00268). Conclusions Asymmetric visual field defects between left and right eyes are common in patients with pituitary adenoma. Severe scotoma is more frequent in the upper quadrant of the temporal hemifield and in the lower quadrant of the nasal hemifield.

ObjectiveTo clarify the outcome of all cases of Rathke's cleft cysts (RCC) treated surgically and followed up in Oxford during a long-term period.Subjects and methodsThe records of all patients with RCC seen in the Department of Endocrinology between January 1978 and June 2009 were reviewed.ResultsA total of 33 patients (20 females, median age 43 years) were identified. At presentation, major visual field defects were detected in 58% of patients and gonadotrophin, ACTH and TSH deficiency in 60, 36 and 36% of patients respectively. Desmopressin treatment was required in 18% of patients. Treatment consisted of cyst evacuation combined with or without biopsy/removal of the wall. Post-operatively, visual fields improved in 83% of patients with impairment, whereas there was no reversal of ACTH or TSH deficiency or of diabetes insipidus. All but one subject had imaging follow-up during a mean period of 48 months (range 2–267). Cyst relapse was detected in 22% of patients at a mean interval of 29 months (range 3–48 months); in 57% of them, the recurrence was symptomatic. Relapse-free rates were 88% at 24-months and 52% at 48-months follow-up. At last assessment, at least quadrantanopia was reported in 19% of patients, gonadotrophin, ACTH and TSH deficiency in 50, 42 and 47% of patients respectively. Desmopressin treatment was required in 39% of patients.ConclusionsIn this study of patients with RCC and long-term follow-up, we showed a considerable relapse rate necessitating long-term monitoring. Surgical intervention is of major importance for the restoration of visual field defects, but it does not improve endocrine morbidity, which in the long-term affects a substantial number of patients.

Object The benefits of treating intracranial aneurysms in the region of the anterior visual pathways are well understood. However, the adverse effects of endovascular stenting across the ophthalmic artery have received little attention. The authors reviewed their experience with patients who had stents deployed across the ophthalmic artery origin. Methods Patients' medical charts and imaging studies were reviewed to identify all patients with a non–flow diverting stent deployed over the ophthalmic artery origin for the treatment of intracranial aneurysms. All patients with neuro-ophthalmic complaints were referred for formal ophthalmological evaluation. Results A total of 104 consecutive patients with 106 aneurysms were identified to meet criteria for inclusion in the study cohort. Preoperatively, 30 patients (29%) described headache symptoms and 32 patients (31%) reported visual complaints. Of the patients with preoperative headaches, 15 (54%) of 28 patients for whom follow-up was available experienced improvement in their symptoms. Of the patients with preoperative visual complaints, improvement was noted in 11 (41%) of the 27 patients for whom follow-up was available, 9 (33%) of 27 patients reported no change in visual symptoms, and 7 (26%) of 27 patients reported progression of symptoms. Visual field defects developing posttreatment were noted to occur in 8 (7.7%) of 104 patients: 3 with immediate postoperative retinal infarcts, 1 with perioperative hemianopia that resolved by the time of discharge, 1 with a subjective visual field defect, 1 with subjective migratory visual field defects, and 2 with nonspecific visual symptoms. Compressive symptoms from aneurysm mass effect were noted in 6 patients preoperatively, with 4 of those patients experiencing persistent worsening, resolution in 1 case, and no change in 1 case. One patient developed a novel cranial nerve palsy from mass effect in the immediate postoperative period. Conclusions Deployment of stents across the ophthalmic artery origin for the treatment of intracranial aneurysms appears to be relatively safe with regard to visual outcomes. Neuro-ophthalmic complaint resolution rates were comparable to endovascular procedures that do not employ stents, with headache resolution rates comparable to coil-only aneurysm obliteration and low rates of retinal ischemic events. For patients presenting with mass effect, stent-assisted coiling appears to be less effective than microsurgery with decompression for relief of compressive symptoms.
