Coccidioidal pericarditis: a case presentation and review of the literature.
BACKGROUND
Pericardial involvement with Coccidioides immitis is an infrequent occurrence with a relatively unfavorable prognosis.


METHODS
A case of coccidioidal pericarditis is presented along with a review of the medical literature on coccidioidal pericarditis to give the clinician a better understanding of the various presentations, complications and outcomes of this disease. Medline (National Library of Medicine, Bethesda) was electronically searched covering the years 1966-2003 using search words coccidioidomycosis and pericarditis.


RESULTS
Sixteen patients were identified from the literature review and one new patient was added. All the patients were males with a mean age of 37.5 years. Chest pain, dyspnea and cough were the most common presenting symptoms. Five patients had evidence of pericardial tamponade, pulsus paradoxus was noted in three patients and three patients presented with pericardial constriction. One patient had Kussmaul's sign, one patient had pericardial frictional rub and another had pericardial knock. Cardiomegaly on chest x-ray was present in ten patients; EKG was noted to have low voltage in five and ST segment elevation in four patients. Delayed hypersensitivity to coccidioidal antigen was reported in nine patients and positive in eight patients. Complement fixation titers were positive in all 11 patients in whom it was assayed. Fifty-three percent of the patients with coccidioidal pericarditis died.


CONCLUSIONS
Coccidioidal pericarditis is a rare disease entity that has a relatively unfavorable prognosis, yet many patients present with diagnostic clues to this disorder. An enhanced understanding of the clinical features of coccidioidal pericarditis may lead to improved outcomes.
