Management of Craniopharyngioma.

J Craniofac Surg 2019 Mar/Apr;30(2):e178-e183

Department of Pathology, Şişli Hamidiye Etfal Training and Research Hospital, University of Health Sciences, Istanbul, Turkey.

Objective: Craniopharyngiomas are one of the most challenging problems for neurosurgeons because of the high recurrence rates due to their localization and associated endocrinological disorders. This study reports the outcomes of surgeries and recurrence rates of 45 craniopharyngioma cases.

Method: Patients who were diagnosed with craniopharyngioma in the authors' clinic between 1998 and 2016 evaluated retrospectively.

Results: A total of 45 patients (25 males and 20 females; age, 3-56 years) who had previously undergone surgery for craniopharyngioma were enrolled and followed up for 12 to 222 months (mean follow-up duration, 73.5 ± 55.2 months). Among these, 25 were children (55.5%) with a mean age of 9.5 ± 4.6 years and 20 were adults (45.5%) with a mean age of 37.2 ± 12.7 years. A total of 39 (86.6%) patients underwent total tumor resection, while 6 (13.4%) underwent subtotal tumor removal. During 12 to 30 months of follow-up, the progression of residual tumor was recorded in 4 patients, 3 of whom underwent surgery and postoperative radiotherapy. Despite the total resection of tumor in their first surgery, 3 patients showed tumor recurrence during 15 to 34 months of the follow-up.

Conclusion: Our findings suggest that the total resection of craniopharyngiomas, when possible, results in a favorable quality of life, with acceptable mortality and morbidity rates.

A Rare Tumor in Childhood Desmoplastic Infantile Astrocytoma: Two Case Reports.

Sisli Etfal Hastan Tip Bul 2018 28;52(3):224-228. Epub 2018 Sep 28.

Department of Pathology, Sisli Hamidiye Etfal Training and Research Hospital, Istanbul, Turkey.

Desmoplastic infantile astrocytomas (DIAs), are rare supratentorial tumors, usually observed in the first 24 months of life. Despite their aggressive appearance, they tend to follow a favorable clinical course. Total or near total resection of tumor is usually the treatment option. Desmoplastic Infantile Ganglioglioma (DIG) and DIA are WHO grade I tumors that have similar clinical and morphological findings. The only criterion in differential diagnosis is the neural component of DIG. These tumors both have dense fibroblastic stroma and positive staining with glial fibrillar acidic protein (GFAP) and CD34. A rare case of desmoplastic infantile astrocytoma presenting with right side partial seizures presented in a 1-year-old child. A rare case of desmoplastic infantile astrocytoma presenting with focal onset generalized seizures presented in a 1-year-old child. Despite their radiological and histological properties, these tumors have a benign course. After 3-year follow-up for the first case and 1-year follow-up for the second case, there was no recurrence.

Chronic subdural hematoma associated with arachnoid cyst of the middle fossa : Surgical treatment and mid-term results in fifteen patients.

Turk Neurosurg 2017 Oct 18. Epub 2017 Oct 18.

University of Health Sciences, Hamidiye Sisli Etfal SUAM, Department of Neurosurgery, Istanbul, Turkey.

Aim: We report the neurological and radiological features, surgical management and Mid-term outcome in a series of patients with chronic subdural hematoma (CSDH) and associated ipsilateral arachnoid cyst (AC) of the middle fossa.

Material And Methods: Between August 2004 and August 2012, 453 patients were treated with diagnosis of CSDH in our clinic. Of those, 15 patients had ipsilateral arachnoid cyst in the middle fossa. A single burr hole craniostomy was performed to drain the hematoma and the AC left intact at first in 14 patients, one patient had no surgical intervention. Follow-up period ranged from 13 months to 88 months (mean 43.07 ± 23.23 months).

Results: The patients having CSDH with AC were found to be younger than the patients with CSDH alone, the mean age was 13.93 ±12.37 years Eleven patients had head trauma 21 to 50 days before admission. Hematoma evacuation through a single burr hole and closed system subdural drainage 2 to 4 days after surgery improved the symptoms in all patients. Two patients developed subdural fluid collection which is treated by subduroperitoneal shunt placement.

Conclusion: Greater prevalence of ACs in patients with CSDHs has been reported in the literature. We recommend the drainage of the hematoma via a single craniostomy and to leave the AC intact as the first choice of treatment if the associated AC is a Galassi type I or II. Additional subduroperitoneal shunting may be performed in patients with Galassi type III cyst.

Computerized Tomography-Guided Stereotactic Biopsy of Intracranial Lesions: Report of 500 Consecutive Cases.

Turk Neurosurg 2017 ;27(3):395-400

Sisli Hamidiye Etfal Research and Training Hospital, Clinic of Neurosurgery, Istanbul, Turkey.

Aim: Computed tomography (CT)-guided stereotactic brain biopsy has been performed in our clinic since March 1998. In this prospective study, we examined the patient data undergoing stereotactic biopsy and the results of biopsies in 500 consecutive patients.

Material And Methods: Between the dates of March 1998 and January 2015, CT-guided stereotactic biopsies were performed by using the Leksell stereotactic frame system (Elekta Instruments EU, Sweden) in 500 patients. A total of 512 procedures were performed in patients consisting of 184 females (36.8%) and 316 males (63.2%), ages ranging from 3 to 81 years (mean 50.40±16.67).

Results: Conclusive histopathological diagnosis was not achieved in 17(3.3%) of 512 procedures. Of the others, 173 (33.8%) were high-grade gliomas, 103 (20.1%) were low-grade gliomas, 36 (7%) were malignant lymphomas, 34 (6.6%) were other types of brain tumors, 82 (16%) were metastasis and 67 (13.1%) were non-tumoral lesions. Complications were occurred in ten cases: 3 tumoral bleedings, 2 hypertensive cerebral hematomas, 2 peroperative convulsions, 1 epidural hematoma, 1 myocardial infarction and 1 brain edema. The patients who developed myocardial infarction and hypertensive thalamic hematoma died. The mortality was 0.4% and morbidity was 1.6% in 512 procedures.

Conclusion: CT-guided stereotactic biopsy is a reliable and a safe procedure in cases with intracranial lesions when histopathological diagnosis is required for the appropriate treatment.

Clip ligation of unruptured intracranial aneurysms: a prospective midterm outcome study.

Acta Neurochir (Wien) 2012 Jul 29;154(7):1135-44. Epub 2012 May 29.

Clinic of Neurosurgery, Şişli Etfal Education and Research Hospital, Istanbul, 34077, Turkey.

Background: We conducted a prospective study to investigate the clinical and radiological outcome in a surgical case series of 176 patients with 203 unruptured intracranial aneurysms (UIA).

Methods: The success of aneurysm obliteration was assessed within 2 weeks after surgery by digital subtraction angiography (DSA). Patients also underwent angiography 5 years after surgery. Clinical outcomes were assessed using the modified Rankin Scale (mRS). All predictors of poor surgical outcomes were assessed using an exact logistic regression.

Results: Overall, 83 % of the patients had a good outcome (mRS score 0 or 1); 10.8 % of the patients had a slight disability (mRS score 2), and 6.2 % of the patients had a moderate or moderate-severe disability (mRS score 3 or 4). The mortality rate was 0 % overall. The most important predictors of outcome were presence of history of ischemic cerebrovascular disease and postoperative stroke. Complete aneurysm occlusion was achieved in 93.5 % of all aneurysms. Sixty percent of treated aneurysms were checked with late follow-up DSA. No cases of hemorrhage from a surgically obliterated UIA were documented in this series during the 7.3 ± 1.4 (SD)-year follow-up period.

Conclusions: If patients are carefully selected and individually assigned to their optimum treatment modality, IUAs can be obliterated by surgery with a low percentage of unfavorable outcomes.

Effects of anterior contralateral cervical microdiskectomy on radiological and clinical outcome.

Surg Neurol 2006 May;65(5):446-52; discussion 453

Clinic of Neurosurgery, Sisli Etfal State Hospital, Istanbul 34077, Turkey.

Background: We have conducted a prospective study to investigate the relationship between cervical spine alignment and clinical outcome in 102 patients undergoing anterior contralateral microdiskectomy without interbody graft or cage.

Methods: Preoperative and postoperative lateral cervical radiographs were obtained, and curvature of the surgically treated spinal segments and the overall curvature of the cervical spine were evaluated in all patients. Clinical outcomes were assessed using the NDI and SF-36.

Results: There was no significant change in the mean overall cervical curvature (C2-C7) angles postoperatively in late follow-up findings (P = .72). It represented a statistically significant mean loss of 2.73 degrees of segmental lordosis (P < .0001). The NDI scores decreased significantly in both early and late follow-up evaluations, and the SF-36 scores demonstrated significant improvement in late follow-up results in our series. Analysis of clinical outcome showed no statistical differences between patients with segmental lordosis or kyphosis.

Conclusion: Despite the kyphosis seen at the treated levels, the overall alignment between C2 and C7 did not change significantly, indicating that the untreated segments of the cervical spine were compensating for focal kyphosis.
