Lumbar disc herniation is a common degenerative disease of the lumbar spine with a prevalence of 1%-3% in some population studies. In 10% of patients, there is a fragment migrated cranially in Macnab's "hidden zone." In selected cases, this fragment can be removed with a translaminar approach that was described in 1998. We provide a detailed description of the technical advantages and pitfalls of the translaminar approach in a consecutive series of 32 patients treated at our institution. ⋯ When performed by dedicated spinal neurosurgeons, the translaminar approach is safe and effective in patients with long-term follow-up. Most patients showed an improvement in ODI. Major pitfalls were related to surgical selection and the narrow working space.

To investigate the relationship between epidurographic contrast dispersal patterns and both immediate and short-term clinical effectiveness of lumbar transforaminal epidural steroid injections (TFESIs) in patients with radicular back pain. ⋯ TFSEIs have a beneficial effect in managing lumbar radicular pain regardless of contrast pattern type. Success rates were higher in type 1 and type 2 than type 3.

Ancient Observation of Spinal Cord Injury: The Case of the Assyrian Lion.
The description of paraplegia is considered a milestone in the history of neurology. The Egyptians provided excellent descriptions of spinal cord injuries, the Bible has several references to paraplegia, and, more recently, the pioneers of neurology described the classic syndromes related to spinal injuries and paraplegia. ⋯ The Lion Hunt of Ashurbanipal, a series of Assyrian palace reliefs from the North Palace at Nineveh dating from approximately 645 BCE, which is now in the British Museum in London, UK, shows King Ashurbanipal hunting lions. Applying modern knowledge of mammalian dermatomes to the images, we reveal a detailed and precise observation of paraplegia after spinal cord injury.

Cerebral abscesses are rare, potentially life-threatening entities that result from local spread or hematogenous dissemination to the brain. Prompt diagnosis and initiation of treatment is key in lowering morbidity and preventing mortality associated with cerebral abscesses. Congenital heart diseases with right-to-left intracardiac shunts can be complicated by brain abscesses via paradoxical embolism of infected microthrombi. Hypoplastic left heart syndrome (HLHS) is a rare congenital heart disease characterized by an underdeveloped left heart that uses intracardiac shunting to achieve adequate systemic circulation. We present the first reported case of a cerebral abscess in a patient with HLHS. The pathophysiology of HLHS and how it predisposes patients to development of cerebral abscesses is discussed. ⋯ HLHS is a rare congenital cardiac malformation. The long-term outcome of patients with this condition continues to improve as treatment paradigms evolve. As such, patients with HLHS are living longer, and their potential to develop cerebral abscesses secondary to their unique systemic circulation is increasing with improved life expectancy. Surgeons and physicians should maintain a high index of suspicion for cerebral abscess in the setting of HLHS.

Percutaneous Endoscopic Lumbar Surgery via the Transfacet Approach for Lumbar Synovial Cyst.
There are currently no high-quality studies on the optimal therapeutic approach for juxtafacet cyst, as treatment guidelines have not been developed. Herein, a novel technique in which we used an endoscopic transfacet approach to treat a patient with symptomatic lumbar synovial cyst is presented. ⋯ Percutaneous endoscopic lumbar surgery could be a new option for the management of lumbar synovial cysts, especially when general anesthesia is not appropriate for the patient.
