Radiology revealed a 3.7 cm enhancing sellar/suprasellar mass with local mass effect, consistent with a pituitary adenoma. On resection, the mass was diagnosed as anaplastic hemangiopericytoma, WHO grade III. The patient experienced residual tumor with two further resections before expiring of a ...
The sellar and suprasellar mass was invisible on the pi- tuitary MRI evaluated after two and four cycles of chemotherapy, and the diameter of the pituitary stalk was 2.2 × 2.1 mm (Fig. 1E, F). The serum IgG4 level dropped to 201 mg/dl one month after the last cycle of chemotherapy...
Craniopharyngioma, a common epithelial neoplasm of the sellar region, is the most frequent suprasellar neoplasm in children(1,2). However, neonatal or congenital tumors are very rare(3–5), as are tumors in the elderly(6). log in via an institution References 1.1.1. Craniopharyngioma Hoffman ...
They typically arise in the suprasellar or hypothalamic region and may extend along the floor of the third ventricle. They often present with “idiopathic” diabetes insipidus, without evidence of a focal mass lesion on MRI (referred to as “occult neurohypophyseal germinoma”). Suprasellar ...
Radiology showedsellar tubercular abscess with suprasellar extension. Microscopic examination of pus collected during surgery showed granulomatous tissues and Acid Fast Bacilli. The response to antitubercular therapy was remarkable.Venkataramana Pamidimukkala...
CT-scan reveals an intra- or suprasellar mass with non-specific features, with calcifications and bone destruction. She underwent transcraneal partial resection of a suprasellar tumor. This lesion was histological diagnosed as epithelioid haemangioendothelioma that showed papillary endothelial hyperplasia....
Computed Tomography Imaging (CT) of the brain showed hyperdense sellar/suprasellar fullness. Magnetic Resonance Imaging (MRI) with and without contrast of the brain showed 2.2 x 1.7 cm enhancing mass in the right cerebellopontine angle with local mass effect concerning for a pituitary tumor. ...
Through a literature review of 8 intrasellar cavernous hemangiomas, we found most lesions are likely to extend into the suprasellar cistern and cavernous sinus, and total resection is difficult. Transsphenoidal approach surgery should be applied for decompression of the optic nerve and biopsy, and ...
Computed tomography and MR imaging demonstrated masses involving inguina, mediastinum and left renal hilum and dumb-bell shaped hyperdense mass, approximately 6.2 x 3.7 mm, that involved pituitary fossa and suprasellar region with adjacent bony destruction. He underwent surgical resection of the tumor....
On follow up imaging studies, lung metastases were shown and the patient died 7 months after the initial diagnosis. Discussion & conclusion Only a few cases of sellar/suprasellar ATRT with lung metastases have been described so far. ATRT should be in the differential diagnosis of fibrous sellar ...
