To determine the association between Modic changes (MC) with other MRI parameters and clinical symptoms of cervical degenerative disc disease (DDD). ⋯ The factor predicting MC type 2 at the C3-C7 cervical levels is submaximal damage to the endplate. The MC rate is increased due to MC type 1 and MC type 2. MC types at the cervical levels may not represent consecutive stages of the same process.

This case report describes an 84-year-old female patient with a growing chronic subdural hematoma (CSDH) that showed an enhanced subdural hyperintense band (SHB) on magnetic resonance (MR) diffusion-weighted imaging over time, indicating that it reflects fresh bleeding from the outer membrane covering the hematoma. The presence of SHB on MR diffusion-weighted imaging of CSDH, possibly reflecting hemorrhagic diathesis of the outer membrane, might be a predictor of enlargement of CSDH.

To assess the overall survival (OS) of internal cerebrospinal fluid shunt (ICSFS) in the adult population. ⋯ On contrary to what one might think, there are few available studies assessing adult ICSFS OS. We used a novel technique to meta-analyse adult ICSFS OS. ICSFS failure rate is maximal within the 3 to 6 post-operative months. Afterwards, the risk slowly decrease over time. At 5 years, less than three quarters of the patients still have a naïve functional ICSFS never revised.

The subsidence of vertebral body replacement may occur after anterior cervical corpectomy and fusion (ACCF) , which may lead to cervical kyphosis, spinal cord compression and neurological dysfunction. The authors aim to investigate the risk factors for early subsidence of 3D printed artificial vertebral (3D-PAVB) after ACCF surgery and to provide guidance for clinical practice. ⋯ The occurrence of early subsidence of 3D-PAVB post ACCF surgery is influenced by two independent risk factors - smoking and low HU. To predict the likelihood of this outcome, it is advisable to consider smoking history and measure CT HU value prior to surgery. A lower CT HU value is indicative of a greater risk of subsidence.

The middle meningeal artery (MMA) is a major dural vessel that plays a significant role in developing chronic subdural hematomas (cSDHs). Understanding its variable anatomy is essential for the effective management of cSDH and the prevention of complications. ⋯ The most common configuration of MMA was Adachi-type IC. The MMA most often originated from the maxillary artery. The posterior branch of the MMA was typically dominant and most frequently originated from the distal segment. There was no significant impact of Adachi type on treatment results or fluoroscopy time.
