A Rare Imaging Diagnosis Behind Persistent Diplopia After Facial Trauma Introduction A 26-year-old man presents to the emergency department after facial trauma. Initially, the injury appears relatively minor. There is no significant neurological deficit, and routine examination reveals only periorbital swelling. However, one symptom raises concern. He complains of persistent diplopia (double vision) . In emergency medicine and radiology, diplopia following facial trauma should never be dismissed. While soft-tissue swelling can temporarily impair ocular movement, persistent symptoms may indicate a much more important diagnosis: Inferior Rectus Muscle Entrapment caused by an Orbital Floor Blowout Fracture. This condition represents one of the most clinically significant orbital trauma findings because delayed diagnosis can result in: Permanent diplopia Extraocular muscle dysfunction Fibrosis of the entrapped muscle Chronic visual disability Reduced quality of life For radiologists, emerg...

Marfan Syndrome and Progressive Vision Loss: A Radiology Case Every Clinician Should Know A 33-year-old woman with a known history of Marfan syndrome presented with progressive bilateral visual loss over several months. Initially, her symptoms appeared to be primarily ophthalmologic. However, advanced medical imaging revealed a striking diagnosis: bilateral posterior lens dislocation (ectopia lentis). This case highlights the critical role of medical imaging, MRI interpretation, and multidisciplinary diagnosis in patients with connective tissue disorders. Although Marfan syndrome is widely recognized for its cardiovascular complications, radiologists frequently encounter imaging manifestations involving the eyes, skeleton, lungs, and vascular system. Understanding these findings is essential because early diagnosis can prevent irreversible visual impairment and life-threatening cardiovascular complications. Clinical Case Presentation A 33-year-old female with known Marfan syndrome pres...

  Introduction Marfan syndrome is one of the most clinically significant hereditary connective tissue disorders, with profound implications across cardiovascular, ocular, and musculoskeletal systems. In modern clinical practice, medical imaging—especially MRI and ophthalmologic imaging—plays a pivotal role in early diagnosis and long-term monitoring. This column presents a case-based, imaging-centered deep dive into Marfan syndrome, optimized for both clinical professionals and advanced blog readers , integrating radiologic interpretation, pathophysiology, and evidence-based management . Case Overview: Progressive Visual Loss in Marfan Syndrome Figure 1. Axial T2-weighted Orbital MRI Bilateral posterior dislocation of the crystalline lenses into the vitreous cavity is observed. The lenses appear as hypointense oval structures displaced posteriorly, confirming ectopia lentis , a hallmark of Marfan syndrome. Figure 2. Normal Orbital MRI Anatomy Normal anatomical positioning of the ...

  Introduction Optic disk swelling and retinal hemorrhages are critical ophthalmologic findings that often signify an underlying neurological or systemic disorder. When both eyes are affected simultaneously, the differential diagnosis must urgently include conditions associated with increased intracranial pressure (ICP), venous obstruction, or systemic vascular disease. In this article, we examine a representative case of a 25-year-old obese female who presented with headache, blurred vision, and transient visual obscurations. Neurological examination revealed bilateral optic disk swelling (papilledema) with retinal hemorrhages , and subsequent MRI/MRV findings demonstrated empty sella, flattened posterior globes, and bilateral transverse sinus stenosis without thrombosis ([Figure 1], [Figure 2]). We will explore the cause, etiology, pathophysiology, epidemiology, clinical presentation, imaging features, treatment, and prognosis of this condition, with emphasis on idiopathic...
