Psoas Abscess Secondary to Appendicitis Complicated by Pleural Effusion

Psoas abscess (PA) is a rare presentation and even more so where appendicitis is the cause. PA often presents with non-specific symptoms resulting in significant mortality, therefore requiring a high index of suspicion requiring timely imaging and diagnosis. PA can be further complicated by pathologies such as pleural effusion which can significantly increase morbidity. This report details a case of psoas abscess secondary to appendicitis which was complicated by right sided pleural effusion.
