The case of a patient with severe fever in the puerperium is presented
. Ultrasound, CT, and MRI revealed multiple myomas; all the myomas, ev
en the smallest ones, were hypodense on pre- and postcontrast enhanced
CT and presented with high signal intensities on T2-weighted MRI. Aft
er hysterectomy, histology demonstrated necrosis of all leiomyomas wit
hout hemorrhage or inflammatory reaction. Therefore, fever was caused
solely by extensive necrotic degeneration of the fibroids, probably du
e to hypoperfusion related to delivery or hormonal changes during preg
nancy and puerperium.
