Introduction. Teratomas are tumours derived from pluripotent germ cells. They
appear most frequently on ovaries. However, other locations are also
possible: testicles, retroperitoneum, stomach, neck, and bottom of the mouth
cavity. It is not very common to find teratomas in two different body
cavities. Case report. A 51-year-old patient visited her doctor complaining
of an intensive pain which suddenly appeared in her low back. The computed
tomography scan of the abdomen was performed, which revealed cystic
formation, 12.5 x 18 cm in size, with remarkable capsule visualization. It
had paraaortic, subdiaphragmatic, retropancreatic and suprarenal left
localisation with signs of compression and pancreatic dislocation. The cystic
formation had a septated appearance filled with clear fluid in all its parts
except at the bottom, where it was dense. The intra-operative finding was
left retroperitoneal mass placed above the left kidney, dislocating
surrounding structures and their infiltration could not be excluded for sure.
A tumour mass passed through the diaphragmatic hiatus and continued in the
left thoracic space. The cyst was only drained and the fenestration was
performed. Three months later, the second operation was
performed-splenectomy, left suprarenaladenectomy, left nephrectomy, aortic
deliberalisation, the left diaphragmatic crus was opened and tumour mass was
completely removed from the thoracic space. The histological examination
showed mature teratoma with morphological characterisations of the skin, so
the definite diagnosis was dermoid cyst. Conclusion. The patient presented
with thoracoabdominal teratoma. Although without malignant transformation,
the teratoma required splenectomy, supraadrenalectomy and nefrectomy due to
its position and size.
