Up-To-Date Magnetic Resonance Imaging Findings for the Diagnosis of Hypothalamic and Pituitary Tumors.

Yonago Acta Med 2021 May 16;64(2):155-161. Epub 2021 Apr 16.

Division of Neurosurgery, Department of Brain and Neurosciences, School of Medicine, Faculty of Medicine, Tottori University, Yonago 683-8504, Japan.

Magnetic resonance imaging (MRI) is the preferred imaging technique for the sellar and parasellar regions. In this review article, we report our clinical experience with MRI for hypothalamic and pituitary lesions, such as pituitary adenomas, craniopharyngiomas, Rathke cleft cysts, germinoma, and hypophysitis with reference to the histopathological findings through a review of the literature. Our previous study indicated that three dimensional-spoiled gradient echo sequence is a more suitable sequence for evaluating sellar lesions on postcontrast T1 weighted image (WI). Read More

Petrosal Approach for Giant Retrochiasmatic Craniopharyngioma: 2-Dimensional Operative Video.

Oper Neurosurg (Hagerstown) 2021 05;20(6):E420-E421

Department of Neurosurgery, Brigham and Women's Hospital, Harvard Medical School, Boston, Massachusetts, USA.

Microsurgical resection of craniopharyngiomas poses significant challenges, which are amplified with tumors in the retrochiasmatic location and larger size. Traditional pterional trans-sylvian, subfrontal translamia terminalis, or interhemispheric approaches provide narrow surgical corridors with obstructed visualization of the tumor by the prefixed chiasm and slit optic carotid window.1-5 The superior extension of the tumor compressing the hypothalamus and third ventricle are likewise inaccessible.

Predicting the location of the preoptic and anterior hypothalamic region by visualizing the thermoregulatory center on fMRI in craniopharyngioma using cold and warm stimuli.

Aging (Albany NY) 2021 03 26;13(7):10087-10098. Epub 2021 Mar 26.

Department of Neurosurgery, Beijing Tiantan Hospital, Capital Medical University, Beijing, China.

Hypothalamic nuclei in the preoptic and anterior hypothalamic region (POAH) are critically involved in thermoregulation and neuroendocrine regulation and can be displaced by craniopharyngiomas (CPs). We aimed to locate the POAH by visualizing hypothalamic thermoregulation through task-related functional magnetic resonance imaging (fMRI) to guide hypothalamus protection intraoperatively. Nine adult healthy volunteers (HVs) and thirty-two adult primary CP patients underwent task-related fMRI for POAH localization by warm (60° C) and cold (0° C) cutaneous thermoreceptor stimulation.

Intrinsic Third Ventricular Papillary Craniopharyngioma: A Report of Five Cases and Literature Review.

Int Med Case Rep J 2021 15;14:83-87. Epub 2021 Feb 15.

Department of Radiology, Pham Ngoc Thach University of Medicine, Ho Chi Minh City, Vietnam.

Background: Craniopharyngiomas are common lesions that occur in the suprasellar region; however, strictly intrinsic third ventricular craniopharyngiomas are rare.

Case Series: We aimed to describe the magnetic resonance imaging features observed in five cases of strictly intrinsic third ventricular papillary craniopharyngiomas, including two cases of mixed cystic and solid tumors and three cases of pure solid masses.

Conclusion: Among the adult population, intrinsic third ventricular papillary craniopharyngiomas should be considered when either solid or mixed cystic and solid masses are observed, in which the solid component shows heterogeneous intensity, heterogeneous and strong enhancement, and is strictly located in the third ventricle.

Medicine (Baltimore) 2020 Dec;99(50):e23183

Department of Radiology.

Most of the craniopharyngioma is considered to derive from residual epithelial cells during the craniopharyngeal canal degeneration. Meningioma accounting for the primary intracranial neoplasm is considered to be mainly derived from cells of arachnoid granulations. Nevertheless, rare cases show coexistence of craniopharyngioma and meningioma. Read More

ESTRO ACROP guideline for target volume delineation of skull base tumors.

Radiother Oncol 2021 03 10;156:80-94. Epub 2020 Dec 10.

Department of Medicine, Surgery and Neuroscience, University of Siena, Siena, Italy; IRCCS Neuromed, Pozzilli, Italy. Electronic address:

Background And Purpose: For skull base tumors, target definition is the key to safe high-dose treatments because surrounding normal tissues are very sensitive to radiation. In the present work we established a joint ESTRO ACROP guideline for the target volume definition of skull base tumors.

Material And Methods: A comprehensive literature search was conducted in PubMed using various combinations of the following medical subjects headings (MeSH) and free-text words: "radiation therapy" or "stereotactic radiosurgery" or "proton therapy" or "particle beam therapy" and "skull base neoplasms" "pituitary neoplasms", "meningioma", "craniopharyngioma", "chordoma", "chondrosarcoma", "acoustic neuroma/vestibular schwannoma", "organs at risk", "gross tumor volume", "clinical tumor volume", "planning tumor volume", "target volume", "target delineation", "dose constraints".
