Intralobar pulmonary sequestration complicating with cryptococcal infection.

INTRODUCTION

Pulmonary sequestration is a rare congenital malformation characterized by accessory lung tissue supplied by an aberrant systemic artery. It often presents with recurrent infections. But fungus infection is exceptional.

OBJECTIVES

To help other clinicians deal with patients with pulmonary sequestration complicating with cryptococcal infection.

METHODS

We reported a case of pulmonary sequestration complicating with pulmonary and eye cryptococcosis and did literature review.

RESULTS

A 20-year-old immunocompetent male patient suffered from eye pain and blurred vision, and received antibiotics and dexamethasone therapy with no improvement. Bacteriology inspection and computerized tomography scan indicated a diagnosis of cryptococcal infection in both eye and lung. Vitrectomy and antifungal agents were administered. Since symptoms fluctuations, lobectomy was operated. The surgery revealed the presence of pulmonary sequestration. Literature review showed that there is no report about pulmonary sequestration complicating with cryptococcal infection so far.

CONCLUSIONS

Pulmonary sequestration is a very important but extremely negligent cause for pulmonary cryptococcal infection.
