Sellar Region Tumor

MRI is a complex, rapidly evolving modality which has assumed an increasingly important role in the diagnosis of Sellar region tumors. It is now the preferred modality for the definitive evaluation and follow-up of the most sellar region tumors. Using different pulse sequence small lesion can be detected even without contrast. Gd-DTPA provides valuable information in MR imaging sellar region tumors, particularly in pre-operative evaluation. This study was conducted to elucidate the accuracy of MRI in pre-operative evaluation of sellar region tumors and its validity by determining sensitivity, specificity, positive and negative predictive value with histopathological correlation. This cross sectional observational study was carried out in the department of radiology and imaging in collaboration with department of Neurosurgery, Dhaka Medical college Hospital, Dhaka during the period of January 2008 to April 2009. MRI of brain was done on 42 patients referred for evaluation of sellar region tumors. The following result and observation were obtained. The age range of the patient was 20 to 80 years. The mean age (HSE) was 34.31(+2.80). Maximum patients were in age group 20-30 years and male-female ratio was 1.8:1. Most sellar region tumor located in the intrasellar with suprasellar extension. Out of 42 patients 37 (88%) patients were truly diagnosed by MRI as sellar region tumors. The sensitivity of MRI to diagnosed macro adenoma was 81.25%, specificity 80.76%, positive predictive value 72.2%, negative predictive value 87.5%, accuracy 80.95%. This study finds that MRI is a valid imaging modality in the diagnosis of pituitary adenoma and sellar region tumor. Bangladesh Med J. 2020 Sept; 49(3) : 1-10

<b><i>Introduction:</i></b> Xanthogranuloma of the sellar region is a rare benign lesion, and there are few cases reported in children. Its histogenesis is controversial, and it is difficult to strictly differentiate it from craniopharyngioma (CP), Rathke’s cleft cyst, or pituitary adenoma. <b><i>Case Presentation:</i></b> A 16-year-old boy presented with a rare xanthogranuloma of the sellar region after complaining of retardation of growth 5 years previously. The ophthalmologic evaluation revealed no visual field disturbance. Endocrinological examination revealed hypopituitarism. Magnetic resonance imaging showed an intrasellar mass extending into the suprasellar region and compressing the optic chiasma, which appeared mixed signals on T1-weighted images. Endonasal transsphenoidal resection of the tumor was performed. Histological analysis of the tumor sections demonstrated granulomatous tissue with cholesterol clefts, hemosiderin deposits, fibrous tissues, multinucleated giant cells, and lymphocyte. Thus, the tumor was pathologically diagnosed as xanthogranuloma of the sellar region, which is different from adamantinomatous CP. There was no epithelial tissue in any part of the tumor including tumor capsule but have focal necrosis and calcification. His endocrinological dysfunction did not recover, so a hormonal replacement was continuously required. <b><i>Conclusion:</i></b> Xanthogranuloma of the sellar region is a rare entity but must be considered in the differential diagnosis of lesions of the sellar region, even in pediatric population. We should think about this disease when dealing with children with stunted growth accompanied by a long medical history. Our case demonstrates the natural progression of the disease, suggesting that xanthogranuloma of the sellar region without epithelial components may be an independent disease.

✓ The authors report the uncomplicated removal of an intrasellar epidermoid cyst that on presentation mimicked a pituitary adenoma. Current controversies regarding the differentiation of this cyst from other cystic lesions of the sellar region are reviewed.
