ABSTRACT
PURPOSE: To describe the frequency of head and/or pancreas uncinate process uptake of 99mTc-HYNIC-TOC, to study its nature, and analyze its diagnostic value. MATERIALS AND METHODS: Retrospective evaluation of 47 consecutive 99mTc-HYNIC-TOC examinations was conducted. Head and/or pancreas uncinate process uptake was considered to be physiological in patients with normal CT at the same episode and in follow-up. It was analyzed if age or diabetes mellitus was justifying the existence or not of uptake. RESULTS: 32.5% patients showed uptake; 73% of them were mild. 84.6% patients with uptake have no pathology and 4% had neuroendocrine pancreatic disease at CT. Neither the age nor the diabetes mellitus established differences in patients without lesion. CONCLUSIONS: Near one-third of patients show physiological uptake by head and/or pancreas uncinate process at 99mTc-HYNIC-TOC scintigraphy. It seems that neither the diabetes nor the ages are factors that determine this physiological uptake.

Presentamos el caso de una paciente de 35 años, nuligesta, con antecedentes de quistectomía ovárica bilateral hace 3 años por un teratoma monodérmico tipo struma ovarii en ovario derecho y quiste hemorrágico en ovario izquierdo. En revisiones periódicas se observa crecimiento progresivo de la tumoración anexial izquierda por lo que se le realiza una nueva laparoscopia y ante los hallazgos se le practica una quistectomía de ovario izquierdo, salpinguectomía derecha y exéresis de múltiples implantes peritoneales. El diagnóstico anatomopatológico fue de struma ovarii izquierdo y strumosis peritoneal. Posteriormente se le realiza rastreo corporal total con 99mTc-pertecnetato para detectar otros implantes peritoneales y SPECT-TAC para localizarlos anatómicamente. Esta exploración ayudó a tomar una decisión terapéutica(AU)
We report the case of a 35-year-old nulliparous woman, with a previous history of ovarian cystectomy diagnosed 3 years earlier due a struma ovarii type of monodermal teratoma in the right ovary and a hemorrhagic cyst in the left ovary. Progressive growth of the left adnexal mass was observed in the periodic medical check-ups. Due to this, a second laparoscopy was performed and, based on the findings, a left ovarian cystectomy, right salpingectomy and resection of multiple peritoneal implants were carried out. The pathology diagnosis was left struma ovarii and peritoneal strumosis. A whole body and SPECT/CT scan with 99mTc-pertechnetate was performed to detect possible peritoneal implants. This study helped to make the therapeutic decision(AU)

This study helped to make the therapeutic decision.
