When a Subtle Cortical Abnormality Explains Years of Seizures A patient in her 30s with a history of drug-resistant seizures undergoes a non-contrast brain MRI. The images reveal a subtle abnormality involving the right frontal cortical region. There is no dramatic mass. No major edema. No obvious contrast-enhancing tumor. Yet this apparently modest MRI abnormality may represent the structural substrate of years of disabling epilepsy. The diagnosis is focal cortical dysplasia (FCD) . Focal cortical dysplasia is one of the most important structural causes of drug-resistant focal epilepsy. It is particularly important in epilepsy imaging because the abnormality can be extremely subtle, sometimes approaching the limits of conventional MRI detection. The uploaded case demonstrates this diagnostic challenge. MRI shows loss of the normal cortical architecture over the right frontal cortical surface, with an adjacent linear cortical/subcortical abnormality demonstrating T2 and FLAIR h...

  Keywords: Fungal Liver Abscess, Hepatosplenic Candidiasis, Liver Abscess CT, Liver MRI, Hepatic Infection, Candida Infection, Hepatic Microabscess, CT Scan Diagnosis, MRI Diagnosis, Medical Imaging AI, Radiology AI, Liver Lesion Differential Diagnosis Abstract A patient presenting with right upper quadrant abdominal pain, fever, and chills may initially appear to have an uncomplicated hepatobiliary infection. However, when CT or MRI demonstrates multiple small hepatic lesions , particularly in an immunocompromised patient, the diagnostic problem becomes substantially more complex. Fungal liver abscess and hepatosplenic candidiasis (HSC) must be considered alongside bacterial liver abscess, metastatic disease, hepatocellular carcinoma, lymphoma, and other infectious lesions. The attached case describes a 48-year-old man with right upper quadrant pain, fever, and chills , with imaging demonstrating multiple hepatic abnormalities. The source material emphasizes that fungal hepat...
