Article Synopsis
- The case report details a rare occurrence of a postpubertal-type teratoma in a 48-year-old male, which appeared as a late recurrence of a previously diagnosed seminoma following testicular surgery six years earlier.
- Imaging tests showed a retroperitoneal tumor with unusual characteristics, leading to a biopsy that indicated a high-grade malignant tumor, prompting neoadjuvant chemotherapy that helped shrink the tumor before surgical removal.
- Further analysis revealed that the original seminoma diagnosis overlooked a mixed germ cell tumor component, underscoring the need for comprehensive histological evaluations in testicular germ cell tumors to better inform prognosis and treatment options.
Mild malformation of cortical development with oligodendroglial hyperplasia (MOGHE) is a recently proposed epileptogenic entity that is difficult to detect on MRI. We present a case of MOGHE that was successfully detected on T1WI-chemical shift-selective saturation (CHESS) MRI. The clinical presentation, MRI including T1WI-CHESS, functional images, and pathology findings of a 14-year-old Japanese girl diagnosed with MOGHE are described.

- Upper respiratory tract villous adenoma (VA) is a rare condition that can lead to muconephrosis and should be considered in cases of pelvic dilation with solid components.
- It has the potential to transform into a malignant form known as mucinous adenocarcinoma.
- When diagnosing, look for signs on CT or MRI, such as contrast enhancement and restricted diffusion, which may indicate the presence of malignancy.
Background And Purpose: Although various neuropsychological problems in Becker muscular dystrophy have attracted attention, there have been few related neuroimaging studies. We investigated brain abnormalities in patients with Becker muscular dystrophy using 3D T1WI and DTI.
Materials And Methods: MR images were obtained for 30 male patients and 30 age-matched healthy male controls.
Background And Purpose: Alternating hemiplegia of childhood (AHC) is a rare neurodevelopmental disease caused by ATP1A3 mutations. Using voxel-based morphometry (VBM) analysis, we compared an AHC patient cohort with controls. Additionally, with single-case VBM analysis, we assessed the associations between clinical severity and brain volume in patients with AHC.

- Subcortical band heterotopia (SBH) is a brain development abnormality diagnosed through MRI, and this study explores its classification and the benefits of using double inversion recovery (DIR) imaging.
- Researchers reviewed MRI findings from 28 SBH patients and found 20 classified as grade 1 and 8 as grade 2 per Di Donato's classification, with 15 patients showing atypical findings on DIR scans.
- The study concludes that DIR imaging effectively highlights subtle abnormalities in white matter, providing better classification and revealing variations of SBH that could indicate underlying pathology.
Background And Purpose: Free-water-corrected diffusion tensor imaging (FW-DTI), a new analysis method for diffusion MRI, can indicate neuroinflammation and degeneration. There is increasing evidence of autoimmune etiology in myalgic encephalomyelitis/chronic fatigue syndrome (ME/CFS). We used FW-DTI and conventional DTI to investigate microstructural brain changes related to autoantibody titers in patients with ME/CFS.

Our study aimed to investigate the effects of age and sex on single-subject gray matter networks using a large sample of healthy participants. We recruited 812 healthy individuals (59.

- I-FP-CIT is an effective tracer for distinguishing between dementia types, specifically dementia with Lewy bodies (DLB) and Alzheimer's disease (AD), but traditional methods sometimes fall short.
- The study used texture analysis on SPECT images from 122 patients to evaluate the heterogeneous depletion of I-FP-CIT and determine its diagnostic usefulness.
- Results showed that texture analysis metrics like skewness and kurtosis had high sensitivity and specificity in differentiating types of dementia, suggesting it’s as effective as conventional binding ratio methods.
Background: Gastrointestinal schwannoma is not a common type of tumor, and lesions originating from the appendix are extremely rare. Herein, we report a patient with appendiceal schwannoma characterized by lymph node swelling.
Case Report: A 67-year-old male patient who had diabetes complained of weight loss.
Mediastinal cavernous hemangioma is a rare lesion requiring diagnosis without invasive procedure due to the risk of hemorrhage, which can be massive and even fatal. Here we describe the successful diagnosis of such a lesion using technetium-99m diethylenetriamine penta-acetic acid human serum albumin (Tc-HSA-D) scintigraphy. A 36-year-old female with a 3-week back pain underwent endoscopic ultrasonography, contrast-enhanced CT, and MRI dynamic study which together revealed a submucosal tumor of the esophagus; likely to be either hemangioma or lymphangioma.
