Isolated sphenoid sinus opacification is often asymptomatic and is not referred for otolaryngology consultation.

Isolated sphenoid sinus opacifications (ISSOs) are clinically important because they can lead to serious complications. However, some patients with ISSOs are asymptomatic, and not all patients are properly referred to the otolaryngology department. Because past studies of ISSOs focused only on patients who received treatment, in this study we selected ISSO cases based on radiology reports, then determined whether these patients had symptoms and were appropriately referred for specialty care.

Therapeutic sclerosis of a small liver cyst that caused obstructive jaundice.

The authors describe the case of a small liver cyst (2 cm in diameter) causing obstructive jaundice that was treated with aspiration and therapeutic sclerosis. The procedure was performed with use of a microcatheter and wire system to access the cyst, which was injected with minocycline hydrochloride. At present, 9 months after treatment, the levels of hepatobiliary enzymes are within normal ranges, and no sign of cyst regrowth has been detected on imaging.
