Epstein-Barr virus (EBV) encephalitis is a rare complication of EBV infection, with most cases described in children. Although some cases of EBV encephalitis have been reported in adults, they have occurred in the presence of other central nervous system infections, superimposed on an underlying neurocognitive disorder, or in immunocompromised states. We present herein a rare case of rapidly progressive EBV encephalitis in an adult male with HIV infection on highly active antiretroviral therapy (HAART) with no pre-existing neurocognitive symptoms...

Hemophilia A and B are one of the most common hereditary bleeding disorders. Patients are predisposed to bleeding spontaneously or after minor trauma in different areas such as the skin, gastrointestinal, or joints. COVID-19 infection has been associated with various clinical manifestations and complications including rarely triggering IgA vasculitis. We report a 23-year-old man who was previously diagnosed with severe hereditary hemophilia A. He presented to our hospital with classic symptoms of IgA vasculitis, complaining of petechiae and purpura in his limbs, fatigue, body aches, poor oral intake, abdominal pain, and watery non-bloody diarrhea...

This study aimed to identify CT-based imaging biomarkers for locoregional recurrence (LR) in Oral Cavity Squamous Cell Carcinoma (OSCC) patients. Our study involved a retrospective review of 78 patients with OSCC who underwent surgical treatment at a single medical center. An approach involving feature selection and statistical model diagnostics was utilized to identify biomarkers. Two radiomics biomarkers, Large Dependence Emphasis (LDE) of the Gray Level Dependence Matrix (GLDM) and Long Run Emphasis (LRE) of the Gray Level Run Length Matrix (GLRLM) of the 3D Laplacian of Gaussian (LoG σ = 3), have demonstrated the capability to preoperatively distinguish patients with and without LR, exhibiting exceptional testing specificity (1...

Bradypus variegatus has unique anatomical characteristics, and many of its vascular and digestive tract aspects have yet to be clearly understood. This lack of information makes clinical diagnoses and surgical procedures difficult. The aim of this study was to evaluate the anatomical aspects of frozen and glycerinated corpses of B. variegatus using computed tomography (CT), emphasizing vascular and digestive contrast studies. Nine corpses that died during routine hospital were examined via CT in the supine position with scanning in the craniocaudal direction...

The patient was a 72-year-old female. She had been taking rivaroxaban for chronic atrial fibrillation; however, she stopped taking it due to anemia and was hospitalized urgently. A contrast-enhanced computed tomography(CT)scan showed a 30 mm mass in the ascending colon, and a colonoscopy revealed ascending colon cancer(cT3, cN0, cM0, cStage Ⅱa). The tumor was hemorrhagic and was thought to have caused the anemia. On day 6 of hospitalization, another contrast- enhanced CT scan showed a poorly contrast-enhanced area in the left atrium, and transesophageal echocardiography revealed 2 left atrial thrombi(27 mm and 17 mm)...

Ovarian mature teratomas are benign, but malignant transformation can occur infrequently, especially in women of advanced age. The tissue that undergoes malignant change is mostly squamous cell carcinoma, although adenocarcinoma has been reported in a small number of cases. The immunostaining results of adenocarcinoma usually show a cytokeratin (CK)7-/CK20+ expression profile, corresponding to lower gastrointestinal tract origin. In this report, we describe a case of mucinous carcinoma arising from an ovarian mature teratoma showing a CK7+/CK20+ profile and discuss its imaging features...

Small bowel internal hernias (IHs), a rare cause of small bowel occlusion (SBO) and small bowel strangulation, while more commonly seen in young adults, can also affect elderly patients and pose a significant diagnostic challenge due to their nonspecific symptoms. In most cases, laparotomy was used to diagnose IHs. However, multidetector computed tomography (MDCT) is usually the best imaging tool to use in the emergency setting for the diagnosis of IHs. An 83-year-old man was admitted to emergency with acute abdominal pain and a coffee-ground vomitus...

Diabetes mellitus type 3c (DM3c) is a diabetes caused by pancreatic pathology. It occurs due to the destruction of the endocrine islet cells. Diabetes diagnosed at the age of 20-30 years share a common dilemma in segregating between the type of diabetes the patient has, as its management varies depending on the type of diabetes the patient is harboring. However, insulin remains the treatment of choice in later decades as the pancreatic reserves of beta cells exhaust, although it takes decades to happen...

Using diffusible iodine-based contrast-enhanced computed tomography (diceCT), we examined the morphology of the oral glands of 12 species of the family Homalopsidae. Snakes of this family exhibit substantial interspecific morphological variation in their oral glands. Particular variables are the venom glands, ranging from large (e.g., Subsessor bocourti) to small (e.g., Erpeton tentaculatum). The supra- and infralabial glands are more uniform in morphology, being the second most developed in almost all the sampled species...
