When Gas Appears Inside the Prostate: 7 Critical CT Findings in Emphysematous Prostatitis What does it mean when gas is visible inside the prostate on CT? In most cases of acute prostatitis, obvious gas within the prostatic parenchyma is not an expected finding. Therefore, intraprostatic gas should be regarded as a major imaging warning sign , particularly when fever, urinary symptoms, diabetes, renal dysfunction, or systemic inflammatory findings are present. One of the most important possibilities is emphysematous prostatitis , a rare but potentially life-threatening infection in which gas-producing microorganisms generate gas within prostatic tissue. The condition may also progress to an emphysematous prostatic abscess , in which an abscess cavity contains gas. The clinical importance is substantial. A previously reported series of 12 patients with emphysematous prostatic abscess reported a mortality rate of 25% , while diabetes mellitus was present in 10 of the 12 patients (83.3%)....

When Rapidly Progressive Dementia Is Not Alzheimer’s Disease A patient in her early sixties develops progressive memory impairment. At first, the symptoms seem compatible with a common neurodegenerative dementia. Several months later, however, the clinical picture becomes increasingly unusual: gait instability, dysphagia, behavioral changes, reduced speech, abnormal eye movements, and rapidly worsening cognitive function. The brain CT may appear almost normal. This is the moment when the diagnostic strategy must change. In a patient with rapidly progressive dementia , the combination of cognitive decline and rapidly accumulating neurological deficits should immediately broaden the differential diagnosis beyond Alzheimer’s disease and vascular dementia. One of the most important diagnoses to consider is sporadic Creutzfeldt–Jakob disease (sCJD) , a rapidly progressive and fatal prion disease. The case presented in the accompanying material illustrates this diagnostic challenge particula...

  Anomalous Right Coronary Artery From the Left Coronary Cusp With Interarterial Course: A Coronary CT Angiography Guide to Diagnosis, Risk Stratification, Treatment, Prognosis, and AI By Dr. SB Lee Abstract A 30-year-old man presented with intermittent chest pain during exercise despite an otherwise unremarkable initial cardiac evaluation. Coronary CT angiography (CCTA) demonstrated an anomalous origin of the right coronary artery (RCA) from the left coronary cusp rather than the normal right coronary sinus. The anomalous RCA subsequently coursed between the great vessels, producing an interarterial course . Importantly, the coronary ostium demonstrated a slit-like morphology and an acute take-off angle , two anatomic features that may increase concern for dynamic coronary flow limitation. This case illustrates why coronary CT angiography should not be interpreted simply as a search for coronary stenosis or calcified plaque. In patients with suspected anomalous aortic origin of a...
