[False diagnosis of para-esophageal hernia--a case report].

Circular foci with a fluid accumulation in the lower right thorax, seen paracardially on a-p films, are primarily indicative of a pulmonary cyst or pulmonary abscess, especially if - as in the case described in this paper - the patient suffers from repeated attacks of coughing accompanied by fever. However, when associated with recurrent vomiting and poor growth in children, the very rare right paraesophageal hernia may be the cause.
