A systemic workup led us to conclude that our patient had a fluoroquinolone-associated tendon injury. Such a disease condition has been recognized as a serious adverse event resulting from the receipt of fluoroquinolones in various clinical settings. Fluoroquinolones have received focus as standard therapeutic agents for liver and/or renal cyst infection because of their lipophilic properties that lead to good penetration into infected cysts. However, reports on fluoroquinolone-associated tendinopathy in patients with ADPKD associated with cyst infection are sparse. We believe the current report illustrates the pitfalls associated with managing patients with ADPKD who are subjected to the administration of fluoroquinolones due to infectious complications.Keywords: ADPKD, renal failure, cyst, infection, fluoroquinolone-associated tendon injuries
