abstract meningeal melanocytoma is a primary melanocytic neoplasm with certain mr and immunohistochemical characteristics worthy to note. in a 38-year-old man with a complaint of headache for a couple of years and recently added nausea, vomiting, diplopia, progressive visual blurring and hearing loss, magnetic resonance imaging (mri) was remarkable for t1 shortening of leptomeninges and certain...

background & aim: lumbosacral pain is extremely common as age increases. spinal instrumentation is sometimes recommended for lumbar canal stenosis and disk herniation surgery. this study aimed at studying the frequency of instrumentation in patients referring to our center. methods & materials/patients: this retrospective cross-sectional study included 1200 patients with low back and/or radicul...

Spinal epidural arachnoid cyst (EAC) is a rare, usually asymptomatic condition of unknown origin, which typically involves the lower thoracic spine. We report a case of posttraumatic symptomatic EAC with lumbar disc herniation. A 22-year-old man experienced back pain and sciatica after a traffic accident. Neurological examination revealed a right L5 radiculopathy. Magnetic resonance imaging dem...

The vast majority of dogs with cervical disk herniation experience cervical pain and only mild motor deficits; therefore, not much is known about the factors that predict recovery in dogs with nonambulatory tetraparesis (NAT) secondary to cervical disk herniation. In this retrospective study, we tested the hypothesis that two previously reported prognostic factors, site of disk herniation and s...

Introduction Lung herniation is a rare condition defined as a protrusion of the pleural-covered lung parenchyma through an abnormal defect or weakness in the thoracic wall. Postoperative lung herniation is reported to result from a preceding operation with inadequate closure of the chest wall. Presentation of case A 77-year-old woman was admitted to our hospital for treatment of hemoptysis an...

[Purpose] To present the outcome of a patient, having sciatica and MRI-verified disc herniation/sequestration who underwent Chiropractic BioPhysics® (CBP®) protocol designed to improve the lumbar lordosis. [Subject and Methods] A 56-year-old male suffered from chronic low back pain and recent sciatica due to lumbar disc herniation despite being under continuous care from three previous chiropra...

We report a rare case of anterior cervical disc herniation associated with dysphagia. A 32-year-old man presented with complaints of dysphagia and concomitant pain in the right arm resistant to conservative therapy. On physical examination with respect to the muscle strength, the right shoulder abduction and flexion of the forearm were 3/5. Lateral X-ray revealed calcified osteophytes at the an...

Vascular compromise is a well-known consequence of brain herniation syndromes. Transtentorial brain herniation most often involves posterior cerebral arteries. However, isolated involvement of contralateral superior cerebellar artery (SCA) during unilateral impending brain herniation is reported only once and we present another case of this exceedingly rare entity. A 24-year-old man was referre...

Spinal cord herniation (SCH) is a rare disease characterized by herniation of the thoracic spinal cord through an anterior dural defect, presenting with progressive myelopathy. A case of a 69-year-old woman who presented with Brown-Sequard syndrome and a bone defect, in which an osteophyte created a hemisphere-like cavity with spinal cord herniation, is presented. The strangled spinal cord was ...

Spinal cord herniation is a rare condition that has become increasingly recognised in the last few years. The authors report a case of idiopathic spinal cord herniation in a 33 year old woman performed with progressive Brown-Sequard syndrome. The diagnosis was made on MR imaging. After repairing the herniation, the patient made a gradual improvement. Potential causes are discussed, including a ...
