Intracranial Neoplasm

Atypical Teratoid Rhabdoid Tumor (ATRT) is a rare malignant intracranial neoplasm more commonly diagnosed in young children. The authors report the case of an 11-year-old boy with a long standing history of slowly progressive weight loss, fatigue, and weakness over 1.5 years whose magnetic resonance imaging revealed a large heterogeneous enhancing dorsally exophytic lower brainstem mass. Examination revealed extreme cachexia, gaze-evoked nystagmus, dysphagia, dysarthria, bilateral dysmetria, and global weakness without ambulation. The protracted history and neuroimaging features were most suggestive of a low grade glioma. However, pathology revealed a hypercellular tumor with large hyperchromatic nucleoli and loss of INI-1 staining on immunohistochemistry consistent with a diagnosis of an ATRT. The child died shortly after surgery due to complications from his brainstem infiltrative disease. This case illustrates the diverse presentation of ATRT in childhood that can clinically and radiographically mimic that of low grade glioma.

Rule Out

In a recent article, Tefft1 has stated that radioactive brain scans must be used to evaluate each child with a convulsive disorder, including those with a normal neurological examination and a normal or nonspecific electroencephalogram. He states that this should be done to rule out the presence of a low grade intracranial neoplasm or arteriovenous malformation. We would like to present three objections to this blanket policy. First, the yield would be extremely low. Follow up of children with epilepsy detected gliomas in 23 of 10,450 children (0.3%) in the study by Page, et al.2 and in 3 of 1,518 (0.2%) studied by Livingston.3

OBJECTIVE Given its minimally invasive nature and effectiveness, stereotactic radiosurgery (SRS) has become a mainstay for the multimodal treatment of intracranial neoplasm. However, no studies have evaluated recent trends in the use of SRS versus those of open resection for the management of brain tumor or trends in the involvement of neurosurgeons in SRS (which is primarily delivered by radiation oncologists). Here, the authors used publicly available Medicare data from 2009 to 2018 to elucidate trends in the treatment of intracranial neoplasm and to compare reimbursements between these approaches. METHODS By using CPT Professional 2019, the authors identified 10 open resection and 9 SRS codes (4 for neurosurgery and 5 for radiation oncology) for the treatment of intracranial neoplasm. Medicare payments (inflation adjusted) and allowed services (number of reimbursed procedures) for each code were abstracted from the Centers for Medicare and Medicaid Services Part B National Summary Data File (2009–2018). Payments per procedure and procedures per 100,000 Medicare enrollees were analyzed with linear regression and compared with tests for equality of slopes (α = 0.05). The average payment per procedure over the study period was compared by using the 2-tailed Welsh unequal variances t-test, and more granular comparisons were conducted by using ANOVA with post hoc Tukey honestly significant difference (HSD) tests. RESULTS From 2009 to 2018, the number of SRS treatments per 100,000 Medicare enrollees for intracranial neoplasm increased by 3.97 cases/year (R2 = 0.99, p < 0.001), while comparable open resections decreased by 0.34 cases/year (R2 = 0.85, p < 0.001) (t16 = 7.5, p < 0.001). By 2018, 2.6 times more SRS treatments were performed per 100,000 enrollees than open resections (74.9 vs 28.7 procedures). However, neurosurgeon involvement in SRS treatment declined over the study period, from 23.4% to 11.5% of SRS treatments; simultaneously, the number of lesions treated per session increased from 1.46 to 1.84 (R2 = 0.98, p < 0.001). Overall, physician payments from 2013 to 2018 averaged $1816.08 (95% CI $1788.71–$1843.44) per SRS treatment and $1565.59 (95% CI $1535.83–$1595.34) per open resection (t10 = 15.9, p < 0.001). For neurosurgeons specifically, reimbursements averaged $1566 per open resection, but this decreased to $1031–$1198 per SRS session; comparatively, radiation oncologists were reimbursed even less (average $359–$898) per SRS session (p < 0.05 according to the Tukey HSD test for all comparisons). CONCLUSIONS Over a decade, the number of open resections for intracranial neoplasm in Medicare enrollees declined slightly, while the number of SRS procedures increased greatly. This latter expansion is largely attributable to radiation oncologists; meanwhile, neurosurgeons have shifted their involvement in SRS toward sessions for the management of multiple lesions.

Abstract Objectives Intracranial neoplasms have distinct diagnostic histologic features and some are common in certain gender and age groups. The most common intracranial neoplasm worldwide is meningioma, followed by gliomas, most especially astrocytic tumors, and then pituitary adenomas. There are geographical differences in the pattern of occurrence of intracranial neoplasms. Few studies have been done in Nigeria to demonstrate the pattern of occurrence, age, and sex distributions of these neoplasms. The aim for this study is to establish the pattern of occurrence with age and sex distribution of different histologic types of intracranial neoplasm in our environment. This study may help portray the health burden of these tumors and aid in epidemiological studies. Methods A total of 296 patients (165 females, 131 males) diagnosed with intracranial neoplasms between January 2008 and December 2017 at Lagos University Teaching Hospital (LUTH), Idi-Araba, Lagos, Nigeria, were retrospectively analyzed. Patients’ data were retrieved from the archives of the Department of Anatomic and Molecular Pathology, LUTH, Idi-Araba, Lagos. Histologic patterns with age and gender distribution were noted. The data obtained were analyzed with SPSS version 23. Results Majority of the patients diagnosed with intracranial neoplasm were between 41 and 50 years of age. The most frequently diagnosed intracranial neoplasm at LUTH within the study period was meningioma (105 cases, median age of 42 years, male to female ratio of 3:7), followed by pituitary adenoma (78 cases, median age of 47 years, male to female ratio of 3:2), and then gliomas (66 case), most especially the astrocytic and oligodendroglial tumors (median age of 37 years, male to female ratio of 2:3). Conclusion The result of the study shows that the pattern of occurrence of primary intracranial neoplasms in our environment is different from that in Caucasians, with meningiomas being the most common, followed by pituitary adenomas and then gliomas.
