Background: Because of the shared origin of limited dorsal myeloschisis (LDM) and congenital dermal sinus (CDS), CDS elements may be found within the fibroneural LDM stalk. When part of the CDS invested in the intradural stalk is left during untethering surgery, inclusion tumors such as dermoid cysts may develop. However, the most appropriate surgical strategy for LDM with CDS is still under debate. Read More

The high contrast resolution provided by magnetic resonance imaging (MRI) compared to all other modalities allows the interpreting radiologist to make a specific diagnosis for many common and uncommon findings. In some cases, the diagnosis can be so certain that there is no differential diagnosis. In this article, we review the most classically recognized findings when interpreting MRI of the pelvis including the following: Ovaries: Simple cyst, hemorrhagic cyst, corpus luteum, dermoid, fibroma/fibrothecoma.

A 51-year-old man developed a sudden headache during golf practice, followed by a high fever. He was admitted with suspected neutrophilic meningitis and was diagnosed with chemical meningitis caused by a dermoid cyst rupture based on the characteristic magnetic resonance imaging (MRI) findings, which showed multiple lipid droplets in his ventricle and cistern. His repetitive golf-swing motion was suggested to be the cause of his dermoid cyst rupture. Read More

This case series showed the sonographic and magnetic resonance imaging findings of two patients with dermal sinuses in the lateral buttocks. According to the 2 present cases, and 8 cases previously reported, the distal sides of the sinuses may be connected to internal tissues, such as the subarachnoid, gluteal fissure, peritoneal cavity, or pelvic bone. Since it is difficult to predict the involvement of the distal side of a dermal sinus based on the dermal pit location, ultrasound and magnetic resonance imaging were postulated as a useful modality to aid evaluation.

The skull vault, formed by the flat bones of the skull, has a limited spectrum of disease that lies between the fields of neuro- and musculoskeletal radiology. Its unique abnormalities, as well as other ubiquitous ones, present particular features in this location. Moreover, some benign entities in this region may mimic malignancy if analyzed using classical bone-tumor criteria, and proper patient management requires being familiar with these presentations.
