“…Two articles were written in Persian [8, 12], whereas the remaining 33 were written in English. Most studies (n = 27) took place in Tehran province [4–5, 8, 11–13, 15–23, 25–29, 31–37] in hospitals and centers affiliated with the three main medical universities in Tehran: Tehran University of Medical Sciences (n = 16) [4–5, 11, 13, 16–17, 19–22, 26, 28–29, 31–32, 37], Shahid Beheshti University of Medical Sciences (n = 6) [12, 15, 18, 25, 27, 34,], Iran University of Medical Sciences (n = 4) [8, 23, 35, 36], and Army University of Medical Science (n = 1) [33]. Only four articles [18, 23, 26, 34] stated that approval by an ethics committee had been obtained.…”

“…The study objectives were categorized as clinical (n = 18 articles, 173 patients), epidemiologic (n = 9 articles [5, 8, 12–13, 16, 26, 28, 33–34], 1,881 patients), pathologic (n = 4 articles [11, 14, 15, 18], 1,160 patients), genetic (n = 2 articles [7, 30], 75 patients), surgical (n = 1 article [21], 172 patients), or radiologic (n = 1 article [29], 23 patients). Study designs were primarily single case reports (n = 16 articles [2–4, 9, 16–17, 19–22, 24, 29, 31–32, 36–37], 19 patients) and cross-sectional studies (n = 15 articles [7–8, 10–14, 15, 18, 25–26, 28, 30, 33–34], 3,271 patients).…”

Purpose Iran lacks a national registry reporting the data of central nervous system (CNS) tumors in children. Consequently, treatment success and failure rates are unknown, and a centralized system for disease-management recommendations does not exist. Methods To critically evaluate the current state of pediatric CNS tumor studies and reporting in Iran, we performed an extensive retrospective analysis of all known reports identified with multiple search engines. Results Of 409 initially retrieved articles, we evaluated 123 matching our inclusion criteria. We further narrowed these reports to 74 by excluding studies pertaining to adult patients only, non-CNS tumors, or brain metastases. We also excluded studies that were performed outside of Iran or that did not contain relevant data from our analysis. We divided the remaining studies into those describing exclusively pediatric patients (3,484 patients) and those describing mixed populations of adults and children (18,641 patients). In total, our analysis included 22,125 patients. Conclusions We identified many limitations in the reporting of studies describing the treatment or prevalence of CNS tumors in children in Iran. Our results may guide future efforts in Iran to improve the care for children with CNS tumors and may provide a valuable template for other comprehensive country- and disease-specific retrospective analyses.

“…Pilomyxoid astrocytoma is a rare glial neoplasm that generally affects young patients up to 4 years old (median age, 10 months), although a few adolescent and adult cases have been reported 2–9 . Typical presentation involves focal neurological or endocrine symptoms, including headaches, visual disturbance, or numbness.…”

A previously healthy 14-year-old boy presented to our facility with a 2-month history of headaches. His headaches were progressively worsening in intensity and though not positional, were reportedly worse in the morning. He developed nausea and vomiting multiple times per week and was given antiemetics and migraine medications on several previous visits to outside hospitals. His symptoms progressed over 48 h to severe headaches with multiple episodes of emesis prompting MRI and subsequent referral. On presentation, his neurological examination was normal, except for grade I bilateral papilledema. Past medical history and family history were unremarkable.MRI of the brain revealed a well-circumscribed, contrast-enhancing mass adherent to the septum pellucidum in the frontal horn of the right lateral ventricle, measuring 1.7 ¥ 2.0 ¥ 1.8 cm, extending into the left foramen of Monro and into the third ventricle ( Fig. 1a-f). The left lateral ventricle was dilated with shift of the septum from left to right, and transependymal flow of CSF was noted. There was no evidence of hypothalamic or parenchymal extension. The lesion was hypointense on T1-and hyperintense on T2-weighted images (Fig. 1a,d). Diffusionweighted MRI (Fig. 1b) and apparent diffusion coefficient map (Fig. 1c) showed restricted diffusion, indicative of a hypercellular neoplasm. 1 MR spectroscopy demonstrated elevated choline and reduced N-actylyaspartate, consistent with a neoplastic process (Fig. 2). A glial neoplasm was considered unlikely since there was no demonstrated connection to the extraventricular brain parenchyma. However, on MR spectroscopy, the elevated choline and reduced N-actylyaspartate were indicative of a glial neoplasm. Pilocytic astrocytoma typically has relatively normal MR spectroscopy. An external ventricular drain was placed into the left lateral ventricle and was followed by craniotomy for gross total resection. Intraoperatively, the tumor was found to be adherent to the medial and anterior portions of the foramen of Monro where it was in close proximity to limbic structures. It was intimately associated with the choroid plexus posteriorly, from which the tumor was tediously dissected free. The more superior and lateral aspects of the tumor were not attached to any structures and were in the body of the ventricle.Postoperatively, the patient experienced improvement in his headaches, allowing the external ventricular drain to be clamped. On postoperative day 6, he was found to have a CSF collection under his operative flap. He underwent placement of a left parieto-occipital ventriculoperitoneal shunt with resolution of this collection. Postoperative MRI revealed a small 1.7 ¥ 0.7 cm area of heterogeneous tissue in the foramen of Monro felt to be a surgically inaccessible residual tumor. The patient later received proton beam radiation therapy. The most recent noncontrasted head CT scan performed 15 months after surgery demonstrated decrease in the size of the ventricles without evidence of tumor growth. PATHOLOGICAL FINDINGSLight...
