“…Unlike typical meningioma, intraparenchymal meningioma does not have a gender preference favoring females. Surprisingly, they occur more in males than females (M: F ratio, 1.9:1), while most meningiomas commonly occur more in females with a male-to-female ratio of 1:2.5 [12][13]. They also present at an unusually early age, with symptoms and signs of increased intracranial pressure, seizures, and focal neurological signs [14].…”

Background: Intraparenchymal meningioma is a rare entity of one of the most common brain tumors. It is challenging to diagnose preoperatively due to the vague clinical presentation and absence of stereotypical radiological features. These atypical features might mislead the differential to favor high-grade gliomas or brain metastasis. Case presentation: We describe a case of a 46-year-old male who presented with vertigo, right-sided sensorineural hearing loss, and bilateral blurred vision. Contrast-enhanced magnetic resonance imaging (MRI) of the brain revealed a large parieto-occipital contrast-enhanced mass with a multi-loculated cystic component and diffusion restriction but without dural attachment. A gross total reaction was achieved, and the histopathological results yielded a WHO grade I meningioma diagnosis. The patient exhibited no signs of recurrence after two years of follow-up. Conclusion: Intraparenchymal meningiomas are difficult to identify without histopathological assessment. We emphasize the importance of considering this diagnosis when outlining an initial differential as it may direct management planning. Total surgical resection is the best treatment modality for such cases; however, radiotherapy is a valuable option. The prognosis of intraparenchymal meningiomas is generally favorable.

“…Gliomas are the most common types of brain tumors, accounting for approximately 80% of all malignant brain tumors. Gliomas rapidly spread to other tissues, they are hard to detect, and they have the highest death ratio among the aforementioned tumor types [ 5 , 6 ]. Gliomas are further classified into low-grade glioma (LGG) and high-grade glioma (HGG) based on their cellular and genetic characteristics.…”

ETISTP: An Enhanced Model for Brain Tumor Identification and Survival Time Prediction

et al. 2023

View full text Add to dashboard Cite

Technology-assisted diagnosis is increasingly important in healthcare systems. Brain tumors are a leading cause of death worldwide, and treatment plans rely heavily on accurate survival predictions. Gliomas, a type of brain tumor, have particularly high mortality rates and can be further classified as low- or high-grade, making survival prediction challenging. Existing literature provides several survival prediction models that use different parameters, such as patient age, gross total resection status, tumor size, or tumor grade. However, accuracy is often lacking in these models. The use of tumor volume instead of size may improve the accuracy of survival prediction. In response to this need, we propose a novel model, the enhanced brain tumor identification and survival time prediction (ETISTP), which computes tumor volume, classifies it into low- or high-grade glioma, and predicts survival time with greater accuracy. The ETISTP model integrates four parameters: patient age, survival days, gross total resection (GTR) status, and tumor volume. Notably, ETISTP is the first model to employ tumor volume for prediction. Furthermore, our model minimizes the computation time by allowing for parallel execution of tumor volume computation and classification. The simulation results demonstrate that ETISTP outperforms prominent survival prediction models.
