Endoscopic Clip — Hemoclip Figure 1. A small radiopaque structure is visible beneath the left hemidiaphragm, projecting over the proximal stomach on the chest radiograph 🔍 How should this device be named? An endoscopic clip is a small metallic device placed onto tissue within the gastrointestinal tract using an endoscope. It is also known as a hemoclip. Figure 2. Magnified radiographic view. The yellow arrow indicates the small radiopaque structure consistent with an endosc

Surgical Implants and Medical Devices — Imaging Identification and Reporting 🔍 How should this implant be named? Metallic mesh corpectomy cageAlternative description: Vertebral body replacement cage What is its purpose? Corpectomy involves partial or complete removal of a vertebral body. A corpectomy cage is placed into the defect created by removal of the vertebral body and associated discs. It supports the anterior spinal column, helps maintain the height of the reconstruc

Case: A 50-year-old man undergoes radiography in the emergency department for an ankle sprain and suspected fracture. Does anything catch your attention on the radiograph? The lateral radiograph shows a small contour irregularity that could be overlooked at first glance. Comparison with the MR images makes its relationship to the fracture clearer. A small irregularity is seen along the dorsal contour of the talar neck. This finding, which is not obvious at first glance, becom

System: Musculoskeletal / Chest Wall Exam Focus: High-Yield Imaging Review Key Imaging Pattern: Deep infrascapular mass with interwoven fat streaks and muscle-like soft tissue on CT 1-Clinical Vignette A 54-year-old man presents with swelling beneath the right scapula and a catching or snapping sensation during arm movements. 2. Board-Style Question Which diagnosis best explains the location and internal architecture of this lesion? A. Lipoma B. Desmoid-type fibromatosis C. E

Case Lumbar MRI in a 46-year-old man demonstrates a prominent extruded disc herniation at L4–L5. T1W Sagittal T2W Sagttal The disc material extends approximately 13 mm caudally from the disc space and occupies a substantial portion of the right paracentral epidural space. At this location, the anteroposterior diameter of the residual dural sac measures approximately 6 mm

System: Neuroradiology / Head & Neck Exam Focus: High-Yield Imaging Review Key Imaging Sign: Classic “Salt-and-Pepper” Appearance on MRI 1. Clinical Vignette A 52-year-old woman presents with progressive right-sided pulsatile tinnitus and mild hoarseness for 6 months. Otoscopic examination reveals a bluish-red retrotympanic mass behind an intact tympanic membrane. Neurologic examination demonstrates mild right vocal cord weakness, suggesting lower cranial nerve involvement. M

Clinical Case Presentation Clinical Case: A 72-year-old female patient presented with non-specific headaches. She has no known history of malignancy, and her neurological examination was entirely normal. Incidental Findings: Periventricular/subcortical ischemic-gliotic foci, a small calcified meningioma, and a developmental venous anomaly (DVA). Comment: The headaches are non-specific and unlikely related to the lesion; the finding is most consistent with an incidental subepe

· ​ It is the most common primary brain tumor in adults, originating from the meninges, the membrane layers surrounding the brain and spinal cord. Approximately 80-85% of cases fall into the World Health Organization (WHO) Grade 1 category and are benign (slow-growing). Rather than invading brain tissue, they generally exert pressure by compressing it from the outside. · In daily radiology practice, small asymptomatic meningiomas are frequently encountered as inci

In daily radiological practice, the posterior-anterior (PA) chest radiograph is a fundamental diagnostic tool. While primarily utilized to evaluate the pulmonary parenchyma, a systematic approach to the "bone window" can uncover crucial anatomical variations. In this clinical article, we review a T1 vertebra posterior element fusion defect (Spina Bifida Occulta) incidentally identified during a routine pre-employment / military health board examination. 1. Fundamental Concept

Case: 46-year-old female patient. Figure 1a & 1b Sagittal T1- and T2-weighted MR images demonstrate multilevel central endplate depressions with similar morphology across the imaged vertebral levels. The red arrow indicates a representative depression. Disc spaces are generally preserved, although some discs show reduced T2 signal. No conspicuous surrounding bone marrow edema is evident on the provided images Radiological Findings: Symmetrically located Schmorl’s nodes are ob

On a plain radiograph (X-ray) I reviewed recently, I encountered a classic lesion straight out of a textbook: A broad-based bony outgrowth located at the proximal medial metaphysis of the tibia, demonstrating clear corticomedullary continuity with the parent bone and projecting distally (downward) away from the growth plate. When we first encounter this image, a single term immediately comes to mind: Exostosis. However, right at this juncture, one of the most intriguing debat

Definition and Key Features Emphysematous pyelitis is a condition where gas is confined to the pelvicalyceal system. Importantly, there is no involvement of the renal parenchyma. This condition is most commonly linked with obstructive urinary tract infections, such as those caused by stones. Gas-producing bacteria, particularly E. coli, are often responsible. It's worth noting that this condition frequently occurs in diabetic patients. Radiological Findings Plain Radiograph O

Clinical Profile Patient: 25-year-old female. Presentation: Slow-growing, painless, firm swelling in the left mastoid region. Radiological Findings: 1. CT: The Architecture A well-defined, lytic lesion significantly expanding the outer table of the left mastoid bone. The sclerotic margins indicate a slow-growing, benign process. 2.
