Question

question b (mandatory) (2 points)
a 70 - year old woman is referred to an ophthalmologist because of difficulty with her right eye. she also has pain in the right upper chest. the findings on physical exam include enophthalmos, miosis, anhidrosis, and ptosis. a chest radiograph shows right upper lobe lesion with bony destruction of the right first rib. which of the following conditions is most likely to be present?
bronchogenic carcinoma
bronchiectasis
pneumoconiosis
sarcoidosis

Explanation:

The patient has Horner's syndrome (enophthalmos, miosis, anhidrosis, ptosis) and a right upper lobe lesion with bony destruction. Bronchogenic carcinoma (lung cancer) can invade the sympathetic chain (causing Horner's) and destroy bones. Bronchiectasis is abnormal bronchial dilation, pneumoconiosis is dust - related lung disease, and sarcoidosis is a granulomatous disease; neither typically causes bony destruction with Horner's syndrome.

Answer:

A. Bronchogenic carcinoma
