Comparative evaluation of normal tissue objective functions in robotic radiosurgery planning for solitary brain tumors

Journal of Applied Clinical Medical Physics, Volume 26, Issue 11, November 2025.
Abstract Background The normal tissue objective (NTO) is an inverse planning approach in radiosurgery, also available for the CyberKnife system. By employing a model function, it aims to achieve precise control over the global dose fall‐off in healthy tissue.

Abdominal Wall Schwannoma: A Rare Case of Target Sign on Ultrasonography

Clinical Case Reports, Volume 13, Issue 11, November 2025.
The target sign observed on ultrasonography. ABSTRACT Schwannoma is a benign tumor derived from Schwann cells of peripheral nerves. Schwannomas arising within muscle or fat exhibit characteristic magnetic resonance imaging (MRI) findings called the target sign, split fat sign, or fascicular sign.

The molecular pathogenesis of schwannomatosis, a paradigm for the co-involvement of multiple tumour suppressor genes in tumorigenesis [PDF]

, 2016
Schwannomatosis is characterized by the predisposition to develop multiple schwannomas and, less commonly, meningiomas. Despite the clinical overlap with neurofibromatosis type 2 (NF2), schwannomatosis is not caused by germline NF2 gene mutations ...

Meningeal Solitary Fibrous Tumor: A Cytological Report With Emphasis on the Usefulness of Immunocytochemical Analysis for STAT6

Diagnostic Cytopathology, Volume 53, Issue 11, Page E210-E214, November 2025.
ABSTRACT Solitary fibrous tumors (SFTs) are rare neoplasms characterized by spindle neoplastic cell proliferation within collagenous stroma and prominent dilated vasculature. They present a wide histopathological spectrum, ranging from hypocellular lesions with a rich collagenous stroma to hypercellular lesions with scant stroma.

Case Report—An Unusual Presentation of Cervical Meningioma as a Carotid Body Mass Diagnosed by Fine Needle Aspiration Cytology

Cytopathology, Volume 36, Issue 6, Page 606-609, November 2025.
We describe an unusual case of cervical meningioma presenting as a carotid body tumour. This case emphasises the importance of cytoradiologic correlation in lesions with atypical imaging findings; and the crucial role of fine needle aspiration cytology in accurately diagnosing masses in precarious anatomic sites of the head and neck.
