Snowballs and Icicles in Susac's Syndrome.

Teaching Point: Snowball-like and icicle-like lesions in the corpus callosum suggest Susac Syndrome.

Idiopathic Tumoral Calcinosis.

Teaching Point: The imaging clues to differentiate idiopathic tumoral calcinosis from other calcified soft tissue lesions include: pseudotumoral appearance with mass effect, bone erosion with intra-osseous protrusion of calcification, lobulated morphology, and peri-articular location on the extensor side.

Idiopathic Granulomatous Mastitis Presenting as Bilateral Breast Abscesses.

Teaching point: Idiopathic granulomatous mastitis is a rare disease that may present as breast abscesses and may mimic other inflammatory, infectious, or neoplastic disorders on imaging.

Muscle Herniation: An Often-Missed Pseudotumor.

Teaching Point: Dynamic ultrasound and knowledge of a clinical history of a soft-tissue lump that increases in volume upon muscle contraction or weight-bearing are crucial in the diagnosis of muscle herniation.

The Co-occurrence of Gender Dysphoria and Autism Spectrum Disorder in Adults: An Analysis of Cross-Sectional and Clinical Chart Data.

Quantitative studies indicate an overrepresentation of ASD in individuals with GD. This study aims to determine the prevalence of autistic traits or ASD in adults with GD using two different data collection methods: (1) cross-sectional data using the social responsiveness scale-adults (SRS-A) and the autism quotient (AQ) (n = 63). (2) Clinical chart data (n = 532). Mean SRS-A scores were significantly higher compared to a norm population. Almost 5% of the patients with GD scored above the cut-off as measured by the AQ. In 32 patients (6%), a certain ASD diagnosis was found in the patient files, which is sixfold higher compared to the general population. Significantly more "birth assigned male" were affected compared to "birth assigned female".
