Subcutaneous panniculitis-like T-cell lymphoma (SPTCL) is a very rare type of cutaneous lymphoma that localizes primarily in the subcutaneous adipose tissue without palpable involvement of the lymph nodes. Most often, it presents as multiple, painless, subcutaneous nodules on the extremities and trunk. In this study, we describe an unusual case of SPTCL that mimicked phlegmonous inflammation; PET/CT revealed massive diffuse involvement of the lower legs, low-grade nodal active disease, and occult involvement of the intra-abdominal visceral fat. A repeat PET/CT study after CHOP chemotherapy revealed complete resolution of abnormal FDG uptake in the initially involved sites.

Healthy brain aging involves changes in both brain structure and function, including alterations in cellular composition and microstructure across brain regions. Unlike diffusion-weighted MRI (dMRI), diffusion-weighted MR spectroscopy (dMRS) can assess cell-type specific microstructural changes, providing indirect information on both cell composition and microstructure through the quantification and interpretation of metabolites' diffusion properties. This work investigates age-related changes in the higher-order diffusion properties of total N-Acetyl-aspartate (neuronal biomarker), total choline (glial biomarker), and total creatine (both neuronal and glial biomarker) beyond the classical apparent diffusion coefficient in cerebral and cerebellar gray matter of healthy human brain.

Background: Neurofibromatosis type 1 (NF-1), a rare autosomal dominant disorder, arises from gene mutations affecting neurofibromin, a Ras GTPase regulator. These mutations activate Ras proteins, triggering clinical symptoms such as skin spots, epilepsy, pain, and tumors. Although gastrointestinal stromal tumors are well-known in NF-1, diffuse intestinal ganglioneuromatosis remains an extremely rare complication.

This case involves a 21-year-old male healthcare student with a medical history of HIV-1 infection for two years and anxiety disorder. He presented to the emergency department with hemoptysis and dyspnea of sudden onset. A thoracic CT scan revealed multiple bilateral nodular ground-glass opacities suggestive of diffuse alveolar hemorrhage (DAH).

Background: Neuroimaging studies have shown that hypothalamic/thalamic nuclei and other distant brain regions belonging to complex cerebral networks are involved in cluster headache (CH). However, the exact relationship between these areas, which may be dependent or independent, remains to be understood. We investigated differences in resting-state functional connectivity (FC) between brain networks and its relationship with the microstructure of the hypothalamus and thalamus in patients with episodic CH outside attacks and healthy controls (HCs).

Loud noise exposure is one of the leading causes of permanent hearing loss. Individuals with noise-induced hearing loss (NIHL) suffer from speech comprehension deficits and experience impairments to cognitive functions such as attention and decision-making. Here, we investigate the specific underlying cognitive processes during auditory perceptual decision-making that are impacted by NIHL.
