A 45yo female presents to ED with niggling chest and epigastric discomfort.

A CXR is performed which yields an unexpected finding.

CT Scan 007 CXR 01

Describe and interpret the CXR

CXR INTERPRETATION

There is right upper lobe collapse as well as a round opacity in the right hilum.

This is an X-ray finding known as the ‘Golden S Sign’ (actually a reverse S), named after radiologist Ross Golden (1889-1975).

Admittedly you have to use your eye of faith to really see the S shape here.

As the right upper lobe collapses completely the horizontal fissure becomes more concave, the edge produced by the elevated horizontal fissure and the hilar mass forms the reverse S shape.

When we see this sign, it raises suspicion for a hilar mass (usually a bronchial carcinoma) causing obstructive atelectasis of the right upper lobe. When the bronchus is obstructed, there will be variable air resorption and fluid retention leading to varying degrees of volume loss.

CT INTERPRETATION

There is incomplete atelectasis of RUL (drowned) due to RUL bronchus obstruction (as suspected on the CXR).

There is bulky confluent right hilar, mediastinal and supraclavicular lymphadenopathy.

There is NO pulmonary mass seen.

There are small pericardial and right pleural effusions.

A CT abdomen (not shown here) also shows extensive bulky lymphadenopathy.

CLINICAL CORRELATION

This CT scan shows a less common cause of the ‘Golden S Sign

The appearance of extensive lymphadenopathy above and below the diaphragm is highly suspicious for lymphoma.

Our patient subsequently had a biopsy of supraclavicular lymph nodes, this confirmed the diagnosis of high-grade B cell lymphoma, and she is currently undergoing chemotherapy.
