However, the recommended follow-up period differs among existing guidelines and consensus is lacking. Thus, this study aimed to suggest follow-up periods for PI based on MRI characteristics.Methods: Between 2007 and 2023, 245 patients who were diagnosed with PI were retrospectively assessed. Their mean clinical and neuroradiological follow-up periods were 74.2 and 27.3 months, respectively. Their baseline clinical and neuroradiological characteristics were analyzed. These 245 patients were divided into two groups: those with PI size progression and those without PI size progression. Additionally, neuroradiological features of each group were analyzed according to presumptive diagnoses of PI.Results: PI size increased in 33 of 245 patients. For the remaining 212 patients, PI size decreased or stayed unchanged. Of the 33 patients with PI size progression, ten underwent surgery. Stalk deviation (p<0.001) and lesion enhancement (p=0.001) were significantly more observed in those with PI size progression than in those without PI size progression. MRI morphological factors were not related to changes in PI size in the presumptive Rathke's cleft cyst group. In the presumptive pituitary adenoma group, absence of tumor enhancement (p<0.001) and stalk deviation (p<0.001) were significantly associated with tumor reduction and progression, respectively.Conclusion: Our findings support an additional guideline for patients with asymptomatic non-functional PI without stalk deviation and enhancement. For these patients, the clinical and neuroradiological follow-up periods could be reduced.","PeriodicalId":72453,"journal":{"name":"Brain tumor research and treatment","volume":null,"pages":null},"PeriodicalIF":0.0,"publicationDate":"2024-01-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"https://www.ncbi.nlm.nih.gov/pmc/articles/PMC10864133/pdf/","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"139693668","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"OA","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

Brain MRI showed a 4.5 cm mass lesion in the right occipital lobe, suggesting either intracranial involvement of HL or a potential meningioma. Despite high-dose methotrexate and steroid treatment, the patient's symptoms persisted, and imaging showed an enlarging mass, leading to surgical intervention. Histopathological examination confirmed central nervous system (CNS) involvement of HL. Postoperatively, the patient underwent whole-brain radiotherapy and demonstrated marked clinical improvement. Our literature review from 1980 to 2023 identified only 46 cases of intracranial HL (IC-HL), underscoring its rarity. Lymphomas represent 2.2% of brain tumors, with 90%-95% being diffuse large B-cell lymphoma (DLBCL). In contrast, the incidence of CNS-HL patients is a mere 0.02%. Notably, IC-HL and intracranial DLBCL have differences in their typical locations and treatment strategies. Unlike DLBCL, which predominantly appears in the supratentorial region (87%), IC-HL is found there in 61.5% of cases. Additionally, 33.3% of IC-HL cases occur in the cerebellum, with 43.5% associated with posterior circulation regions. Furthermore, while biopsy followed by chemotherapy induction is a common strategy for DLBCL, 81.8% of IC-HL cases underwent surgical resection, and only 18.1% had a biopsy alone. The distinct characteristics of IC-HL tumors, including their larger size, attachment to the dura, and fibrotic nature with clear boundaries, might account for the preference for surgical intervention. The unique features of IC-HL compared to DLBCL highlight the need for distinct considerations in diagnosis and management.","PeriodicalId":72453,"journal":{"name":"Brain tumor research and treatment","volume":null,"pages":null},"PeriodicalIF":0.0,"publicationDate":"2024-01-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"https://www.ncbi.nlm.nih.gov/pmc/articles/PMC10864131/pdf/","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"139693665","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"OA","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

Formerly, brainstem gliomas were classified mainly based on MRI features and location. However, since 2016, the World Health Organization's brainstem lesion classification requires tissue biopsy to reveal molecular characteristics. Although modern techniques of stereotactic or navigation-guided biopsy ensure accurate biopsy of the lesion with safety, biopsy of brainstem lesions is still generally not performed. Here, we report a focal brainstem lesion mimicking brainstem glioma in a 9-year-old girl. Initial MRI, MR spectroscopy, and 11C-methionine positron emission tomography (PET) features suggested low-grade glioma or diffuse intrinsic pontine glioma. However, repeated MR spectroscopy, perfusion MRI, and 18fluorodeoxyglucose PET findings suggested that it was more likely a non-tumorous lesion. As the patient presented not with a neurological manifestation but with precocious puberty, the attending oncologist chose to observe with regular follow-up MRI. The pontine lesion with high signal intensity on T2-weighted MRI regressed from the 6-month follow-up and became invisible on the 1.5-year follow-up MRI. We reviewed brainstem glioma-mimicking lesions in the literature and discussed the key points of differential diagnosis.","PeriodicalId":72453,"journal":{"name":"Brain tumor research and treatment","volume":null,"pages":null},"PeriodicalIF":0.0,"publicationDate":"2024-01-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"https://www.ncbi.nlm.nih.gov/pmc/articles/PMC10864136/pdf/","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"139693667","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"OA","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

Basic anatomical sequences such as pre- and post-contrast 3D T1-weighted, T2-weighted, fluid-attenuated inversion recovery, T2*-weighted, and diffusion-weighted imaging (DWI), are fundamental for assessing tumor location, extent, and characteristics. Advanced techniques like DWI, diffusion tensor imaging, perfusion imaging, magnetic resonance spectroscopy, and functional MRI offer insights into cellularity, vascularity, metabolism, and function. To enhance consistency and quality, standardized protocols for pediatric brain tumor imaging have been recommended by expert groups. Special considerations for pediatric patients, including the minimization of anesthesia exposure and gadolinium contrast agent usage, are essential to ensure patient safety and comfort.

We are presenting the first reported case from Pakistan of a 19-year-old woman who underwent awake epilepsy surgery to treat cortical dysplasia. She had a history of generalized tonic-clonic seizures since her childhood and was referred to our clinic due to an increase in seizure frequency. EEG and MRI identified the epileptogenic focus in the right parieto-temporal region. The patient underwent a neuro-navigation guided awake craniotomy and an excision of the epileptogenic focus in the right parieto-temporal region. The procedure was carried out using a scalp block and dexmedetomidine for conscious sedation, enabling the patient to remain awake throughout the surgery. Intraoperative mapping and electrocorticography were used for complex multidisciplinary care. Post-resection corticography showed no spikes along the resected margins. The patient was discharged without any complications and remained free of symptoms a year after the surgery. Awake epilepsy surgery is a viable option for removing epileptogenic foci while preserving vital cognitive functions. However, it is seldom used in low- and middle-income countries such as Pakistan. The successful outcome of this case underscores the need for greater awareness and availability of epilepsy surgery in resource-limited settings.

We performed survival analyses and assessed prognostic factors.Results: The cohort included 10 patients with pineocytoma (PC), 13 with pineal parenchymal tumor of intermediate differentiation (PPTID), and 20 with pineoblastoma (PB). Most patients presented with hydrocephalus at diagnosis. Most patients underwent an endoscopic third ventriculostomy and biopsy, with some undergoing additional resection after diagnosis confirmation. Radiotherapy was administered with a high prevalence of gamma knife radiosurgery for PC and PPTID, and craniospinal irradiation for PB. Chemotherapy was essential in the treatment of grade 3 PPTID and PB. The 5-year progression-free survival rates for PC, grade 2 PPTID, grade 3 PPTID, and PB were 100%, 83.3%, 0%, and 40%, respectively, and the 5-year overall survival rates were 100%, 100%, 40%, and 55%, respectively. High-grade tumor histology was associated with lower survival rates.
