Pseudopodagra in young women

Acute Calcific Tendinosis of the Flexor Hallucis Brevis

“…Of these 28 reported cases, 22 were women (79%). [2][3][4][7][8][9][12][13][14]21,22,24,25,[27][28][29] The female predominance may be explained by footwear, but underdiagnosis in men who may have been presumptively diagnosed with gout may play a role. 8,9,12,13,22 Clinically, symptoms of acute calcific tendinosis can include severe pain, swelling, erythema, and decreased range of motion, 3,4,7-9,12-14,22,24,29 all of which are nonspecific.…”

“…In these cases, symptoms markedly improved within days and completely resolved within a few weeks. 3,4,8,9,12,13,22,24,25 There has been only one case report of forefoot calcific tendinosis where the patient's symptoms were refractory to anti-inflammatory medication, prompting surgical resection of the calcific deposit with subsequent good clinical recovery. 21 More recently, ultrasound-guided needling of a calcific deposit in the flexor hallucis brevis tendon was performed with immediate resolution of symptoms.…”

“…In the rheumatology literature, the term hydroxyapatite pseudopodagra has been used because the clinical symptoms can mimic gout. A literature search for the variable terms used to describe this entity (also calcifying tendinitis, calcific periarthritis, peritendinitis calcarea, and periarthritis calcarea 24 ) revealed only a few case reports [2][3][4]7,9,[12][13][14]21,22,24,25,27,29 and a few small case series 8,28 describing forefoot calcific tendinosis. There has been only one case report of forefoot calcific tendinosis reported in the foot and ankle orthopedic literature, and it involved the adductor hallucis tendon.…”
