Overview
Other Imaging Findings
- Fibreoptic bronchoscopy with bronchoalveolar lavage (BAL) and transbronchial lung biopsies are usually needed to substantiate the diagnosis of alveolar hemorrhage.
- In patients who represent with esophagitis due to SLE, upper gastrointestinal barium study can be performed. Possible investigations include mucosal granularity from reflux esophagitis, and, in severe cases, ulceration.
- If the patients presents with the symptoms of gastritis or peptic ulcers, the stomach and duodenum should also be evaluated using a double-contrast technique.
- If the patients presents with the symptoms of acute cholecystitis, scintigraphy imaging findings can be done. The findings include gallbladder wall thickening at US and a nonfunctioning gallbladder at hepatobiliary.
- Osteonecrosis:
- Bone scintigraphy can be non specific or shows hyperemia of the affected bone and osteogenesis due to avascular necrosis (AVN)
- On echnetium-99m methylene diphosphonate bone scans, photopenic areas will be seen primarily that will eventually progress to osteoblasts activity and increased radiotracer uptake at the margins of the infarction
- An abnormal intraosseous phlebogram may be diagnostic as well and by the demonstration of an elevated intramedullary pressure
