Introduction. Foetal tumours are relatively rare; prenatal diagnosis enables
additional diagnostics, and thus the decision on the continuation of
pregnancy and planning of delivery. The paper presents prenatal ultrasound
diagnostics of foetal head tumour with additionally analyzed magnetic
resonance imaging (MRI). Case Outline. On ultrasound imaging, in a 27-year
old nullipara, a tumour of the foetal head was suspected at the 22nd
gestational week. By consultative ultrasound, a 45x41x50 mm echogenic soft
tissue tumour with hypoechogenic areas was confirmed, which originated from
the left side of the skull spreading towards the neck on the left behind the
ear. On colour Doppler no vascularisation was seen within the tumour but
several vessels were seen along the border-line and on the surface. The scan
showed no associated abnormalities. Karyotype was 46, XY. MRI scan using
triplanar SSFSE and HASTE sequences was done at 26 weeks and confirmed a
84Č45Č71 mm tumour originating from the scalp, spreading along the
endocranium over the entire surface of the fronto-temporal sqama and left
parietal bone. The tumour did not disturb the integrity of the internal
tabula, and did not spread intracranially. Based on these findings, the
diagnosis of haemangioma was made. At 38 weeks gestation, a 3810 g male
infant was delivered by Caesarean section. A bluish, well-defined,
non-pulsatile tumour arising from the left frontoparietal region was seen,
thus confirming the diagnosis of haemangioma. Conclusion. MRI improved
delineation of the tumour facilitating better planning of postnatal
management and mode of delivery, with the information on the postnatal course
and prognosis. In the prenatal period, MRI following an ultrasound diagnosed
foetal tumour, is an additional part of diagnostic examinations, and is not
contraindicated during pregnancy.
