Signal

Relationship between tumor and its surrounding tissue

1

5 × 9

T1WI showed isointense and slight hypointense, T2WI showed slight hyperintense, and the degree of enhancement after dynamic enhancement was weaker than that of normal pituitary.

There was no obvious deviation of the pituitary stalk, and the bone of the sellar floor collapsed slightly. There was no obvious abnormality in the optic chiasm. There was no obvious abnormal signal in the bilateral cavernous sinus.

2

6 × 8

T1WI showed isointense and hypointense, T2WI showed isointense, and dynamic enhancement showed enhancement and less uniform, weaker than normal pituitary enhancement.

The pituitary stalk shifted to the right, and the bone of the sellar floor collapsed slightly. The left cavernous sinus was involved.

3

20 × 13

Patchy short T1, slightly long T2 signal, and enhanced lesions showed mild enhancement.

The pituitary stalk is not clearly displayed. There was no abnormal signal in the bilateral cavernous sinus, and the optic chiasm was slightly compressed and raised.

4

5.8 × 7

T1WI showed slightly low signal, T2WI showed uneven slightly high signal, and the lesions showed mild enhancement after enhancement.

The pituitary stalk was in the middle, no obvious elevation of the dorsal sella, no obvious collapse of the sellar floor, and no obvious abnormal enhancement of the bilateral cavernous sinus structure.

5

38 × 30

The signal intensity was similar to that of white matter and enhanced significantly after enhancement.

There was a gourd-shaped isosignal shadow in the pituitary area with a clear boundary and no abnormal widening of the ventricular system. No displacement of midline structure.

6

25 × 30

T1WI showed isointense and slightly hypointense, T2WI showed mixed hyperintense, cystic changes were seen in some lesions, and the parenchyma showed obvious homogeneous enhancement after dynamic enhancement.

The pituitary stalk shifted to the right, and the bone of the sellar floor collapsed. The visual chiasm is not clear. The boundary between the lesion and bilateral cavernous sinus was not clear.

7

3.3 × 8.3

The boundary was clear, isointense and hypointense on T1WI, isointense on T2WI, and enhanced after dynamic enhancement, which was less homogeneous than normal pituitary.

The pituitary stalk shifted to the right, and the bone of the sellar floor did not collapse.

8

33 × 28

T1WI showed equal low mixed signal, T2WI showed equal high mixed signal, and enhanced scan showed uneven enhancement.

The tumor invaded the bilateral cavernous sinus, protruded to the parasellar and suprasellar, extended into the suprasellar cistern and sphenoid sinus, destroyed the bone at the sellar floor, and compressed the bilateral optic chiasm.

9

13 × 14

On the contrast-enhanced scan, the lesions showed relatively low signal intensity.

Partial filling defect of the left cavernous sinus, mild enlargement of the sella turcica, partial loss of the anterior and inferior bone, and mild right deviation of the pituitary stalk.

10

12.3 × 14.1

T1WI sequence showed edge isointensity and internal patchy hyperintensity. T2WI sequence showed mixed isointensity. After contrast enhancement, the lesions were peripheral enhancement, and the middle part of the hyperintensity had no obvious enhancement, and the signal was uneven.

The sella turcica was enlarged, the bone of the sellar floor was slightly compressed, and the optic chiasm was compressed and moved up.
