45 years Female (DOB:12/1/1970)Reason: Hx pituitary germinoma. Also cavernous malformation. History: HA.PROVIDER/ATTENDING NAME: RIMAS V. LUKAS RIMAS V. LUKAS Since prior exam patient is undergone right frontal craniotomy for right frontal lobe surgery. There is redemonstration of a lesion centered in the right half of the corpus callosum along the genu measuring 16 x 16 mm axial dimensions previously measured similar dimensions. It has a popcorn-like appearance on T2 and T1 imaging. There is a focus of encephalomalacia within the adjacent right frontal lobe.Incidental note is made of partial empty sella.Small foci of signal loss and susceptibility imaging are present along the superior aspect of the vermis and the superior aspect of the right cerebellar hemisphere. One of these is visible on the T2 imaging. On the prior exam these were less conspicuous.There is redemonstration of a focus of low signal on susceptibility imaging along the anterior and left paramedian aspect of the pons. This was present on prior exams and is unchanged.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.
1.Findings are compatible with the cerebral cavernous malformation in the genu of the corpus callosum. This does not appear to be significantly different than the prior exam.2.Since prior exam the patient is undergone right frontal craniotomy. There is encephalomalacia present along the right frontal lobe.3.There is no evidence for germinoma on this exam.4.There is redemonstration of a hemorrhagic focus in the pons which is unchanged prior exam. This is nonspecific given its small size. Differential considerations include include cavernous malformation is also causes of microhemorrhage.5.There is redemonstration of some small hemorrhagic lesions in the cerebellum. These are more conspicuous on the current versus the prior exam. It is possible that these represent small cavernous malformations they are nonspecific and could represent other types of lesions including radiation effect
