Characteristics of Rosai-Dorfman Syndrome Primarily Involved in the Central Nervous System: A Three-Case Report and Review of Literature.
This study aimed to summarize the clinical characteristics of Rosai-Dorfman disease primarily involving the central nervous system and to explore diagnosis and treatment. ⋯ Rosai-Dorfman disease with multiple lesions primarily involving the central nervous system is rare. Imaging characteristics are similar to meningiomas, and the pathological features include lymphocytes and plasma cells reaching tissue cells with large volume and abundant cytoplasm. Surgery is the preferred treatment, as the effects of steroid administration and radiotherapy are not apparent.

The precise mechanism of nucleus pulposus proliferation in the degeneration of the intervertebral disk pathogenesis remains to be implicated. MicroRNAs (MiRNAs) are a class of 18-22 nucleotides, which are small, noncoding RNAs that inhibit protein translation by binding to the 3'-UTR of target gene. Recent studies have shown that miRNAs play a crucial role in various cell biologies such as cell proliferation, invasion, migration, and cell cycle. However, the role of miR-184 in nucleus pulposus proliferation is still unknown. ⋯ These results demonstrated that miR-184 and the GAS1/Akt pathway may be a potential therapeutic target for intervertebral disc degeneration.

Review Case Reports
Intracranial neurenteric cyst with an enhanced mural nodule and melanin pigmentation: radiological-pathological correlation.
An intracranial neurenteric cyst (NC) is a rare congenital benign lesion that usually has a well-demarcated cystic appearance without contrast enhancement on magnetic resonance imaging (MRI). In particular, an intracranial NC with an enhanced mural nodule is extremely rare. ⋯ We present this rare case and emphasize that an NC should be considered in the differential diagnosis of intracranial cystic lesions with an enhanced mural nodule.
