Pedrada syndrome and massive degeneration of the Achilles tendon: a case report

This case report explores “Pedrada syndrome,” a rare vascular condition characterized by spontaneous intramuscular venous hemorrhage of the calf, often mistaken for muscular injuries like tennis leg. The study presents the case of a 65-year-old male with comorbidities, including diabetic polyneuropathy, who developed a massive degeneration of the Achilles tendon (AT) due to complications from Pedrada syndrome. Following an initial unnoticed heel ulcer, the patient experienced sudden pain in the calf, misattributed to muscle strain. Persistent symptoms led to imaging studies revealing a 5 cm AT lesion and soft tissue infection. A two-stage surgical intervention was performed, including debridement and subsequent AT reconstruction with a cadaveric allograft. The patient achieved satisfactory functional recovery after six months. This report highlights the diagnostic challenges of Pedrada syndrome and emphasizes the need for a multidisciplinary approach, especially in patients with peripheral neuropathies, to prevent severe complications.
