Background: Chorionic carcinoma is a highly malignant gynecological tumor, frequently originating from trophoblastic cells in the uterus after fertilization. Early erosion releases cancerous cells into the circulation to invade surrounding organs without primary symptoms and signs. Methods: One case of choriocarcinoma sellar region metastasis was analyzed, utilizing clinical data, MRI and patho...

BACKGROUND A sellar spine is a bony spur protruding anteriorly from the central portion of the dorsum sellae. Its etiology is an ossified notochordal remnant of the cephalic end of the notochord. It is presumed to be a congenital malformation based on magnetic resonance imaging (MRI) findings of sellar spine in a 4-year-old boy. A sellar spine should therefore be detectable at birth with or wit...

BACKGROUND Endonasal transsphenoidal microsurgery is often adopted in the resection of pituitary adenoma, and has showed satisfactory treatment and minor injuries. It is important to accurately localize sellar floor and properly incise the bone and dura matter. METHODS Fifty-one patients with pituitary adenoma undergoing endonasal transsphenoidal microsurgery were included in the present stud...

Background and Importance. Sellar tuberculomas are extremely rare lesions with nonspecific clinical manifestations. The tuberculous infection of the pituitary gland and sellar region is characterized by the presence of an acute or chronic inflammatory reaction and may occur in the absence of systemic tuberculosis. The diagnosis is difficult prior to the surgery. An adequate diagnostic and antit...

Primary sarcomas of the sellar region are uncommon, although a wide variety have been reported. To date, no cases of primary synovial sarcoma have been described as occurring at this site. We report an immunohistochemically and molecular genetically confirmed primary synovial sarcoma involving the sellar/parasellar region and cavernous sinus in an adult male. Subtotal resection and radiosurgery...

chondrosarcoma is a mesenchymal tumor composed of tumor cells producing cartilage. it is more common in older age and often affects the axial skeleton. we report a rare case of chondrosarcoma mimicking a sellar and suprasellar mass with parasellar extension. a 40 yr woman presented with decreasing visual acuity and headache. magnetic resonance (mr) image revealed a cystic sellar and suprasellar...

A 67-year-old female patient presented with visual field impairment and hyperprolactinemia. Imaging revealed a sellar and suprasellar mass and during the evaluation of the sellar lesion, papillary thyroid carcinoma (PTC) was diagnosed by fine-needle aspiration biopsy in a long-standing euthyroid multinodular goiter. The patient did not have a previous history of PTC. Total thyroidectomy confirm...

Clinically significant sellar cysts unrelated to pituitary adenomas are uncommon. Intracranial cholesteatomas are also rare and are most common in the middle ear and mastoid region. We report an even rarer case of cholesteatoma in the sellar region-a challenging diagnosis guided by clinical presentations, radiological signs, and biopsy, aiming at emphasize the importance of considering choleste...
