Background: Neurofibromatosis 1 (NF1) has a broad spectrum of clinical manifestations, most typically involving café-au-lait spots and skin neurofibromas. Only 2% of patients with NF1 have symptomatic spinal tumors.
Case Description: A patient with a previous diagnosis of NF1 presented with cervicalgia, dysphagia/mild dysphonia, gait alteration, and progressive hypoesthesia involving all four limbs. The magnetic resonance documented a giant dumbbell neurofibroma arising between the C2 and C3 levels which extended toward the foramen magnum, causing medullary and bulbar compression. The major challenge of surgical management was the enormous size and location this C2-C3 (5 cm × 4 cm × 5.1 cm) lesion.
Conclusions: Compression of the foramen magnum attributed to a dumbbell giant spinal neurofibroma at the C2C3 level resulting in prebulbar cisterns should be among the differential diagnostic considerations for patients presenting with tetraparesis and underlying NF1.

Morphometric Analysis of Radiological Features of Pituitary Tumors and Optic Pathway Distortion Associated with Visual Impairment in Pituitary Macroadenomas with Suprasellar Extension.

Article Synopsis
- The study aimed to assess the relationship between visual impairment and suprasellar extension in pituitary macroadenomas using preoperative MRI to identify patients at risk of preoperative visual deficits.
- Analyzed data from 97 patients revealed that factors like the duration of visual symptoms, specific measurements of suprasellar extension, and the anatomical distortion of the optic nerves were significant predictors of visual impairment.
- The findings indicate that understanding tumor shape and optic pathway changes can help predict visual impairment risks, which may inform better surgical planning and timing for affected patients.

The surgical management of extensive jugular foramen schwannomas presents a formidable challenge, aiming for gross total resection while minimizing complications. Here, we present a case with giant triple dumbbell-shaped jugular Foramen Schwannoma. A 45-year-old male with a one-year history of a left neck mass underwent surgery.

Objective: Trigeminal schwannoma (TS), though a rare and benign tumor, becomes a significant surgical challenge due to its intricate location. This study aims to detail the long-term functional outcomes and tumor control post-surgical resection.
Method: We analyzed a multicentric retrospective cohort of 39 patients operated on for a TS in five tertiary centers between January 1993 and July 2022.

Article Synopsis
- A cardiac lipoma is a rare, non-cancerous tumor found in the heart that can affect how the heart works.
- In this case, a 35-year-old man had a tumor that grew both inside and outside his right atrium, which was discovered through imaging tests.
- He had surgery to remove the tumor, and doctors confirmed it was a lipoma, with no problems found during a check-up three months later.
