Can you name this eponymous condition on this sagittal STIR❓❔ Answer 👇  Dias disease (talar avascular necrosis). Mild flattening of the talar dome with diffuse altered MR signal of the talus with relative sparing of the anterior aspect of the talar head. Low signal on T1, heterogeneous high signal on T2 & STIR weighted images. A serpiginous line is seen in the talar dome immediately below the superior articular surface being of low signal on T1, T2 & STIR.

Can you spot the abnormality? 🤔... 👉Swipe for answer  Always check the fat pads on a lateral elbow radiograph.  The anterior fat pad is normally present. This is the black stripe you see at the anterior cortex of the humerus. It is a normal finding UNLESS elevated as in this case (outlined in red). This is also known as the "sail sign" ⛵ and indicates a joint effusion & probable fracture.  The posterior fat pad should NEVER be seen on a normal study. So if you see it, as in this case (blue) ➡️ abnormal. Think joint effusion and fracture even if you don't see a fracture ‼️ Source: Accident and Emergency Radiology: a survival guide  #radiology #radiologycafe #medical #medicaleducation #learningradiology #learnradiology #teachmeradiology #radiopaedia #statdx #xrayoftheday #xrays #radiography #radio #radiologist #radtech #radtechstudent #radiologyresident #radiologyregistrar #ultrasound #mri #ct #scan #medical #interventionalradiology #neuroradiology #frcr #exams #usmle
How to interpret the AP shoulder radiograph 👇  Always ask these 5 questions:  1. Is the humeral head lying directly below the coracoid process❓Yes 👉anterior dislocation.  2. Does the humeral head have a walking stick shape (or a light bulb shape 💡), and does its articular surface parallel the glenoid margin❓No 👉 use other views to rule out a posterior dislocation.  3. Is the acromioclavicular joint normal i.e. do the inferior cortices of the clavicle and acromion process align❓No 👉 subluxation or dislocation at the acromioclavicular joint.  4. Is the coracoclavicular distance more than 1.3 cm❓Yes 👉 stretching or rupture of the coracoclavicular ligaments  5. Is there a fracture of the head or neck of the humerus, the glenoid margin, the clavicle, the body or neck of the scapula, or a rib fracture⁉️ It's that easy!

How well do you know your liver segments⁉️ The liver is subdivided anatomically into 8 segments in an anticlockwise fashion.  The horizontal left and right portal veins separate the superior segments (II, IVa VIII, VII) from the inferior segments (II, IVb, V, VI)  The three vertical hepatic vein branches further subdivide the segments 👉Right branch: this separates segments VII, VI from VIII, V 👉Middle branch: this separates segments VIII, V from IVa, IVb 👉Left branch: this separates segments IVa, IVb from II, III  The caudate lobe (segment I): this is autonomous, receiving vessels from both the left and right portal vein branches and the hepatic artery 👉 it has an independent venous drainage directly into the IVC  Source: Grainger & Allison's Diagnostic Radiology Essentials  #radiology #radiologycafe #medical #medicaleducation #learningradiology #learnradiology #teachmeradiology #radiopaedia #statdx #xrayoftheday #xrays #radiography #radio #radiologist #radtech #radtechstudent #radiologyresident #radiologyregistrar #ultrasound #mri #ct #scan #medical #interventionalradiology #neuroradiology #frcr #exams #usmle
What's going on here⁉️ 🤔 Answer 👇  Bilateral lower lobe collapse.  Bilateral triangular opacities are seen with obscuration of the medial portions of the hemidiaphragms. The cause was mucous plugging.

Where is the abnormality⁉️ 🤔  Answer 👇  An inhaled peanut in the right main bronchus.  Inspiration film (left): the right lung is hypertransradiant (ie blacker) compared with the left. Following rapid expiration (right), air trapping on the right is now obvious. Mediastinal displacement to the left is evident. Note: food (including peanuts) will not be visible on a radiograph.

Inspect the occipitomental (OM) views as follows 👇  Concentrate on the stool's legs. For each leg, compare the injured side with the normal side. Look for asymmetry.  1. Leg 1 = zygomatic arch  2. Leg 2 = frontal process of zygoma  3. Leg 3 = orbital floor  4. Leg 4 = lateral wall of maxillary antrum  5. Look for #fractures and a fluid level (blood) in the maxillary antrum, sinus air on the soft tissues or in the orbit  Apply this rule 👉 if any one of the legs is #fractured then always, always double check whether the other 3 legs are intact #tripodfracture  Source: Accident & Emergency Radiology: A survival guide  #radiology #radiologycafe #medical #medicaleducation #learningradiology #learnradiology #teachmeradiology #radiopaedia #statdx #tripodfracture #xrays #radiography #radio #radiologist #radtech #radtechstudent #radiologyresident #radiologyregistrar #ultrasound #mri #ct #scan #medical #interventionalradiology #neuroradiology #frcr #exams #usmle

🇺🇸Case 12, Slide 4. Final Thoughts. 👉Right frontal lobe area of FLAIR/T2 - hyperintensity without restricted diffusion may indicate vasogenic oedema. Vasogenic oedema, local patchy gyre-form enhancement and white matter cyst formation are not highly specific findings. 🗝Final differential: 1️⃣vasculitis (inc. Wegener’s), 2️⃣leukoencephalopathy (inc. iPML, cystic leuko-y), 3️⃣lymphoma, 4️⃣glioma (inc. low grade - astrocytoma), 5️⃣encephalitis (inc. viral) 🔎Further tactics: continuous followup, excluding autoimmune factors, spinal tap PCR. Preffered additional noninvasive method: MRS. 🇷🇺Случать 12, Слайд 4. Заключительные мысли. 👉Повышение сигнала FLAIR/Т2ВИ белого вещества правой лобной доли и мозолистого тела без ограничения диффузии указывают на вазогенную природу отёка. Как вазогенный отёк, так и локальное гириформное усиление серого вещества, сами по себе или вместе не обладают высокой специфичностью. 🗝Дифференциальный ряд: 1️⃣васкулит (в т.ч. Вегенера), 2️⃣лейкоэнцефалопатия (в т.ч. воспалительная прогрессирующующая мультифокальная лейко-я, кистозная лейко-я), 3️⃣лимфома ЦНС,  4️⃣глиома (в т.ч. высоко -дифференцированная астроцитома), 5️⃣энцефалит (в т.ч. инфекционный) 🔎Тактика: наблюдение, исключение аутоиммунной природы заболевания, ПЦР ЦСЖ. Неинвазивными методом углубленного изучения может послужить МР

Calcaneal compression fracture: Calcaneal fractures are serious but uncommon injuries; they account for only 1 to 2% of all fractures. However, if not diagnosed and treated promptly, they can result in long-term disability. Up to 10% of these fractures are missed at initial presentation in an emergency department.  Typically, these fractures result from a high-energy axial load to the foot (eg, a fall from a height onto the heels). Because these fractures require great force, they are often accompanied by other serious injuries; 10% of patients with a calcaneal fracture have a thoracolumbar compression fracture. . . . #radiology #learnradiology #letsstudy #letsstudyhard #calcaneus #calcanealfracture #radiologictechnologist #radiograf #studyhard #studymotivation #radiologia #medicalstudent #medicine #doctorstrange #doctors #xray #ctscan #studytogether
Case 17: 31-year-old otherwise healthy male presents to the ED with left upper extremity swelling and redness after weightlifting.

chisel fracture: An incomplete fracture of the head of the radius, in which the fracture line extends distally from the centre of the articular Surface.  The Mason classification is used to classify radial head fractures and is useful when assessing further treatment  type I: non-displaced radial head fractures (or small marginal fractures), also known as a "chisel" fracture type II: partial articular fractures with displacement (>2 mm) type III: comminuted fractures involving the entire radial head IIIa: fracture of the entire radial neck, with the head, completely displaced from the shaft IIIb: articular fracture involving the entire head, consisting of more than two large fragments IIIc: fracture with a tilted and impacted articular segment type IV: fracture of the radial head with dislocation of the elbow joint In general type I injuries can be treated conservatively whereas type II injuries require open reduction and internal fixation (ORIF). Type III and IV injuries often require early complete excision of the radial head. #learnradiology #medstudent #letsstudyhard #letsstudytogether #radiology #xrayoftheday #xray #rontgen #radiologyforlife #medicine
Giant Bullae  What are Giant Bullae? A giant bulla is a complication of emphysema. In areas of the lung completely damaged by the disease, air pockets can develop. These areas threaten the patient’s health not only because of the underlying emphysema. As an air pocket—a bulla—grows, it takes up space in the chest cavity and can encroach on the lungs. Severe disruption of normal lung function due to the crowding and pressure is a common result.  Bullous emphysema is also known as vanishing lung syndrome. It is most often treated by surgical removal of the bulla, which can grow to 20 centimeters—more than a foot—in diameter. A bulla that takes up a third or more of the space in and around the affected lung is called a giant bulla. Because of its close association with emphysema, giant bullae are most often found in older patients who smoke or used to smoke. A giant bulla is classified as a chronic obstructive pulmonary disease (COPD), along with chronic bronchitis and asthma.  #radiologyforlife #learnradiology #radiologists #itssimplyamazing #studytogether
