A case of a small-bowel schwannoma with diffuse familiar lipomatosis is described. This case underlines the rarity of the neoplasm and its probably chance association with subcutaneous lipomatosis. The intestinal neoplasm was diagnosed preoperatively by upper gastrointestinal endoscopy and a small-bowel enema; computed tomography scan confirmed the intestinal lesion. Attention is focused on the morphological features of intestinal schwannomas and their biological behaviour.

Skull base tumors such as meningiomas and schwannomas are often pathologically benign. However, surgery for these tumors poses significant challenges because of their proximity to critical structures such as the brainstem, cerebral arteries, veins, and cranial nerves. These structures are compressed or encased by the tumor as they grow, increasing the risk of unintended injury to these structures, which can potentially lead to severe neurological deficits.

Objective: Predicting treatment response in patients with vestibular schwannomas (VSs) remains challenging. This study aimed to evaluate the use of pre-treatment normalized apparent diffusion coefficient (nADC) values and magnetic resonance (MR) imaging characteristics in predicting treatment outcomes in patients with VSs undergoing radiosurgery.
Methods: The MR images of 44 patients with VSs who underwent radiosurgery at our institution were retrospectively reviewed, and the patients were categorized into tumor control ( = 28) and progression ( = 16) groups based on treatment response after treatment initiation, with a median follow-up duration of 29.

Purpose: Objective information about the central auditory pathways in vestibular schwannoma can guide strategies for hearing rehabilitation and prognostication. This study aims to generate this information using diffusion tensor imaging (DTI).
Methods: This is a prospective observational single center study including 35 patients with vestibular schwannoma and 40 controls.

Background: Intracerebral schwannomas are rare tumors resembling their peripheral nerve sheath counterparts but localized in the CNS. They are not classified as a separate tumor type in the 2021 WHO classification. This study aimed to compile and characterize these rare neoplasms morphologically and molecularly.
