Foix-Alajouanine syndrome is an extremely rare yet important differential diagnosis for subacute lower limb weakness in middle-aged to elderly adults. Current understanding of the pathophysiology of this disease, along with recent publications on successful endovascular interventions, has shifted the perspective and clinical approach for its management. Nonetheless, neurosurgical pathways for clinical treatment are still preferred over endovascular embolization.

Article Synopsis
- Early treatment of intracranial lesions is crucial but challenging to differentiate, as each type requires different treatment strategies; Cerebral computed tomography perfusion (CTP) imaging is effective in visualizing and quantifying brain lesions' vascularity.
- This study evaluated the effectiveness of Hounsfield units (HU) and CTP in distinguishing various intracranial space-occupying lesions over a five-year period, involving 244 patients with conditions including glioblastomas, primary central nervous system lymphoma, metastases, and abscesses.
- Results indicated that combining rCBV and HU measurements enhances diagnostic accuracy for differentiating lesions, and the simplicity and availability of CTP make it a valuable tool for diagnosing and managing brain tumors.
Background: Postsurgical spinal infections are a severe complication and a challenge to the neurosurgeon due to their complex management. Revision surgeries and the removal of hardware are usually necessary. Recently, advances in nuclear medicine have made it possible to employ radiotracers to identify infections.
