Incidental ⁶⁸Ga-DOTATATE uptake in uterine leiomyoma

Excerpt

A 41-year-old woman with a history of neuroendocrine carcinoma of the lung underwent successful resection 1 year before (small cell lung carcinoma, G3, Ki-67 65%). The patient underwent a ⁶⁸Ga-DOTATATE PET/CT scan for postsurgical follow-up (PHILIPS; Gemini TF; 16-slice CT, 100 mA, 120 kV; 3.0 min/bed; 512 × 512 matrix, 60-cm field of view). The images (Fig. 1) from the ⁶⁸Ga-DOTATATE PET/CT scan showed focal increased radiotracer activity in the pelvic cavity that was located in the uterus (SUVmax of 5.0). However, no significant anatomical changes were found by CT in the area of focal uptake. Subsequently, transvaginal ultrasonography revealed a soft tissue mass with a diameter of 2.3 cm in the myometrium, and color Doppler flow imaging showed abundant blood flow signals within the lesion. A detailed history revealed that the patient had dysmenorrhea, abnormal vaginal bleeding for 3 years, gradually aggravated in the last 8 months. These findings were suggestive of uterine leiomyoma. Minor surgery was performed and the lesion was resected. The pathological examination confirmed that the lesion was consistent with uterine leiomyoma.
