Type IV sacrococcygeal teratoma presenting with complete urinary obstruction

Abstract

Sacrococcygeal teratomas (SCT) are a rare entity, occurring in approximately 1 of every 35,000 to 40,000 births [1]. Although it remains the most common extragonadal germ cell tumor, type IV SCT represents less than 10% of those [1]. The diagnosis is challenging, as the initial presentation has been described as chronic pelvic pain, rectal mass and mild to severe urinary symptoms [2-4]. To our knowledge urinary obstruction is a rare initial presentation, described in the literature only three times [5–7]. Here in, we present a rare case of type IV SCT with a complete urinary obstruction as an initial symptom.
