Headcheese sign refers to a radiological pattern in a chest CT scan that can be associated with several pathological entities, from different etiology such as an infection, an immune response or drugs. The name comes from the juxtaposition of 3 different densities with well-defined margination of hazy ground-glass opacity that looks like a “paté”.
Knowledge to Care
Differential Diagnosis is a key step in Medicine, but it is poorly practiced by young and old doctors. Some of the “reasons” that especially young doctors and residents expose to justify this fact are the following:
An Urinary Bladder Perforation is an uncommon complication but could be useful for a clinical reasoning exercise.
Undiagnosed and Rare Diseases are a group of complex entities usually difficult to categorize in clinical practice.
Parents have a big challenge when they detect some development anomalies in their children because it is usually very difficult to categorize the problem. Health professionals, usually pediatricians, have also big difficulties to frame the anomalies inside a particular syndrome.
A 65-year-old woman went to Medical Oncology with upper left abdominal pain and on the left shoulder. He had been suffering from this pain for about 6 months before a road accident, but had increased in the last month, without nausea or vomiting. Three years earlier she had a diagnosis of colon adenocarcinoma, but there were no data of recurrence in the last visit.
CLINICAL DIAGNOSIS: Lymphedema, cellulitis
FINAL DIAGNOSIS: Thrombosis in the inferior vena cava and right iliac vein
TYPE OF DIAGNOSTIC ERROR: Delayed Diagnosis
