Impact of prenatal diagnosis of fetus-in-fetu

Abstract: Fetus in fetu (FIF) is an extremely rare condition (1/500,000 live births) in which a fetiform structure is incorporated into the body of its twin. FIF can be a diagnostic dilemma due to its similarity to a teratoma, but identification of FIF is important for subsequent medical and surgical management. We compare two cases of fetal masses diagnosed on prenatal imaging that were later identified as FIF through further radiological, surgical, and pathologic evaluation. We use these cases to illustrate key pre- a… Show more

“…17,18 Prenatal detection and postnatal follow-up of FIF is very beneficial, as it can be done multidisciplinary follow-up and thus be more successful in the withdrawal. As in the case reported by Sewell et al 6 in which the 27-year-old pregnant woman, at the 28th week of gestation, detected a white mass in the abdomen and then confirmed the FIF by ultrasonography. In our case, one week after birth, the mass was completely excised and the patient had a good evolution and hospital discharge, reinforcing the importance of the diagnosis in the gestation period.…”

“…Establishing the difference is important to establish pre-and post-natal management. 6 The diagnosis made in prenatal care allows for the follow-up of complications that may occur, such as abdominal distension, intestinal obstruction, hydronephrosis, hydrops, jaundice, compression of neighboring tissues and respiratory 2/6…”

“…4 Spencer R, citado por Gómez-Cadena y su grupo, 1 propuso una clasificación para los gemelos siameses de acuerdo con el sitio predominante de unión: toracópagos (tórax), onfalópagos (abdomen), pigópagos (sacro), isquiópagos (pelvis), craneópagos (cráneo), cefalópagos (cara) o raquípagos (espalda). [1][2][3][4] Otra forma de clasificación es gemelos (A,B); órganos herniados a través de la pared abdominal (lóbulo izquierdo del hígado e intestino delgado), comprobado con medio de contraste positivo vía oral; y estructuras óseas de ambos gemelos, independientes (C).…”

“…En estos casos, la evaluación ultrasonográfica prenatal es un estudio importante, como ocurrió en nuestra paciente, por la sospecha durante el embarazo de gastrosquisis, hasta evidenciar los gemelos al momento del parto; no obstante, ante la duda diagnóstica puede indicarse, incluso, resonancia magnética para una mejor caracterización. 1,2,9 El estudio de elección para el diagnóstico prenatal es la resonancia magnética, pues puede evaluar de mejor forma las estructuras anatómicas, y ofrece buena interfase entre los tejidos y mejor campo de visión, sobre todo en el tercer trimestre, cuando el feto es más grande y tiene menor movimiento. La resonancia magnética es útil cuando los hallazgos ecográficos del feto son ambiguos o inciertos.…”
