Thus the distinction between synovial chondromatosis and synovial chondrosarcoma, is a real dilemma. However, this distinction has a major interest in view of the evolutionary and therapeutic modalities are very different. in this work, we report a case of synovial chondrosarcoma, a woman of 62 years old , whose diagnosis was confirmed by histological examination. We will then discuss the contribution of individual authors, and all scientific testing, to establish specific criteria and objectives, that suggest the aggressiveness of chondrosarcoma, hidden behind the benignity of synovial chondromatosis.

We present the case of an 83-year-old patient with typical symptomatology suggesting progressive supranuclear palsy with characteristic imaging.

Fulminant Susac syndrome—a rare cause of coma: The history of the fatal course in a young man

The onset and progression patterns are multiple, mainly of three modes. Fulminant evolution is exceptional, rarely reported across literature. We report through this case a Susac syndrome in a young man in whom evolution was fatal. Magnetic resonance imaging is essential to raise the diagnosis and for follow-up, with almost pathognomonic findings, all the more useful as the clinical triad is usually incomplete and as the encephalopathy is the most limiting of the symptoms.

This condition occurs generally after a severe traumatism or surgical procedure. However, in some rare cases, the herniation can happen spontaneously. Nontraumatic clival meningoceles present an extremely rare entity and correspond to a herniating pachymeningeal collection containing cerebrospinal fluid through a zone of fragility in the clivus. Clinical presentation ranges from simple headache or rhinorrhea to severe complications such as recurrent bacterial meningitis or nerve compression. Computed tomography provides an analysis of the bone and magnetic resonance imaging provides a superior contrast resolution, helping to distinguish among the various types of clival lesions. We report the case of a young woman with a long history of idiopathic intracranial hypertension, who presented with a worsening headache. Magnetic resonance imaging confirmed a clival meningocele without other complications and the patie...
Incidental optic nerve sheath arachnoid cyst: A rare case finding with literature review

They comprise 1% of intracranial masses, and the orbital location is even more rarely reported in history especially in the pediatric population. They might be discovered as an asymptomatic finding on imaging performed for a concomitant condition or, in most reported cases, as a result of ophthalmic impairment. They can be isolated or associated with gliomas, neurofibromas, empty sella syndrome, and frontotemporal porencephalic cysts. Computed tomography scan shows a non-enhancing liquid cystic lesion, and magnetic resonance imaging remains the best assessment tool confirming the similarity of the fluid to cerebrospinal fluid and evaluating the optic nerves. Herein, we report the case of an incidental discovery of an intraorbital arachnoid cyst on magnetic resonance imaging in a 53-year-old woman with a history of epilepsy. No treatment was performed as the cyst...
