Summary: The purpose of this study was to assess the value of perfusion-weighted imaging (PWI) in differentiating sellar and parasellar tumors using magnetic resonance imaging (MRI). Analysis of 124 brain and pituitary MRI examinations showed that meningiomas had significantly higher values of relative cerebral blood volume (rCBV) compared to non-functional and hormone-secreting pituitary adenomas (PitNET). Additionally, meningiomas showed higher relative peak height (rPH) values compared to adenomas. DSC PWI imaging adds significant value to conventional MRI examinations and can aid in differentiating equivocal pituitary tumors.

Summary: This review provides a brief overview of pituitary and parasellar anatomy, focusing on the imaging features of common and rare pituitary pathologies with clinical management implications. Imaging and basic clinical history often lead to a specific diagnosis or narrowed differential, potentially eliminating the need for surgical intervention in certain cases. Localization of abnormalities and recognition of characteristic imaging features are crucial for diagnosing pathologies in the pituitary region, guiding treatment planning for biopsy or resection.

Summary: Compression of the anterior visual pathways by sellar and parasellar masses can lead to irreversible and devastating visual loss. Optical coherence tomography (OCT) is a noninvasive imaging technique that can be used to analyze the optic nerve and retinal structures, providing a valuable tool for detection and monitoring of compressive optic neuropathies and chiasmopathies. OCT parameters can also predict visual outcomes and guide treatment decisions.

Summary: The aim of this study was to analyze the global trends in the use of minimally invasive approaches in managing sellar, suprasellar, and parasellar diseases. The results showed geographic and demographic variations in the use of endonasal endoscopic approach (EEA), with developing countries lagging behind in its utilization. The findings suggest a need for further promotion and education on EEA in these regions.

Summary: The study conducted endoscopic endonasal approach on 153 patients with sellar and parasellar lesions, mainly pituitary adenomas, craniopharyngiomas, and other rare lesions. The main surgical complications were cerebral spinal fluid leak, bleeding, and endocrinological complications such as diabete insipidus and panhypopituitarism.

Summary: Sellar/parasellar tumors (SPTs) rarely present symptoms during pregnancy, making their management challenging due to risks to both mother and fetus. A retrospective study of 6 cases in Italy showed that monitoring and multidisciplinary management is crucial for pregnant patients with symptomatic SPTs. A pragmatic algorithm was proposed, suggesting a wait-and-see approach and surgery for severe cases.

Summary: This study investigated the epidemiology, clinical manifestations, management, and treatment outcomes of sellar/parasellar lesions during the transition age. The results showed that managing these lesions in adolescents requires an integrated and multidisciplinary approach. Hormone and metabolic disorders may occur many years after treatment, highlighting the importance of long-term follow-up.

Summary: This study presents the clinical implementation of an MR simulation program for radiotherapy planning. Over the past 5 years, a total of 8798 MR planning sessions were carried out, accounting for 25% of all CT simulations performed in the same period. The report provides detailed information on clinical workflow, optimized MR acquisition protocols, patient setup, and strategies to overcome challenges, which can be used by institutions interested in implementing an MR planning program.

Summary: This retrospective study aimed to determine the necessity of intraoperative MRI scans following endoscopic endonasal pituitary adenoma surgery. The results show that for adenomas limited in the sellae and not invading the cavernous sinus, an IO-MRI scan is not necessary, but it is strongly recommended if there is any suprasellar and parasellar extension and/or cavernous sinus invasion.

Summary: This study retrospectively analyzed a 10-year experience of renal tumor cryoablation on a 1.5 T MRI unit, showing acceptable morbidity and high survival estimates. Further studies are needed to evaluate whether the potential reduced incidence of adverse events justifies large-scale implementation of this interventional modality.

Summary: Hematological neoplastic mass lesions in the sellar region are rare, with a higher prevalence in females. Clinical presentation includes ophthalmoplegia and diabetes insipidus. Chemotherapy is the primary treatment, emphasizing the importance of early diagnosis for timely intervention and pituitary function recovery.
