Malignant neoplasm of cervix uteri, unspecified site Examination of participant in clinical trialClinical question: Evaluate for abnormality; compare to previous scan There is redemonstration of an ill-defined area of enhancement located in the right middle frontal gyrus extending to the right precentral gyrus. Enhancement is located within the sulci and adjacent packing meninges. This includes a precentral sulcus as well as the right superior frontal sulcus. Estimated measurement of the area of enhancement is 21 x 14 mm mm axial dimensions and has not changed substantially since the prior exam. There are surrounding vasogenic edema in an area measuring approximately 43 x 39 mm axial dimensions. Previously vasogenic edema measured 27 x 26 mm axial dimensions. There is some susceptibility artifact associated with the enhancement.There is redemonstration of pachymeningeal thickening associated with underlying perivascular space and parenchymal enhancement at the anterior aspect of the right frontal lobe.Pachymeningeal thickening measures approximately 4 mm on the current examination on the prior exam measured approximately 2 mm. There is associated signal change in the right frontal lobe this involves gray and white matter and measures approximately 16 by this axial dimensions when measured 11 x 16 mm axial dimensionsNormal vascular flow voids are present in the distal carotid and vertebral arteries, the basilar artery and the proximal anterior, middle and posterior cerebral arteries as well as the internal cerebral veins and superior sagittal sinus.The visualized portions of the paranasal sinuses are clear. The visualized portions of the mastoid air cells are clear. The visualized portions of the orbits are intact.
Focal meningeal enhancement and intraparenchymal enhancement along the right middle frontal gyrus is not substantially changed in extent when compared to the prior exam. The associated vasogenic edema however has increased. Right frontal polar enhancing lesion has enlarged since the prior exam. Differential considerations do include metastatic disease. A multifocal infectious process would be less likely. Granulomatous disorder and lymphoma are also differential considerations.
