“Ultrasound results interpretation?”

I have the following two ultrasound reports taken four months apart for groin inflammation. I understand the first one, but the second is vague to me:

1st one:

Indication: Generalized enlarged lymph nodes.

Comparison exams: None.

Findings: Grayscale and color flow imaging of the right inguinal region provided. Within the right inguinal region is a lymph node measuring 12 mm in length with homogeneous echotexture of the cortex.
There is also suggestion of a small lipoma versus a second lymph node measuring 9 x 7 mm.

IMPRESSION:

Single lymph node and a possible second lymph node versus lipoma of the right inguinal region as described above. Otherwise, echotexture within the right inguinal region is unremarkable in appearance.

2nd one:

HISTORY: 43-year-old male with planes of pain in the right groin.

EXAM: Real-time and duplex sonography of the arterial flow in the right inguinal region including spectral analysis and color-flow Doppler.

FINDINGS: Sonographic evaluation was performed and demonstrates venous flow, no evidence of thrombus in either the right or left common femoral vein is present.

Bilateral lymph nodes are identified. The exam is otherwise unremarkable.

IMPRESSION:
1. The common femoral veins are patent.
2. Note is made of bilateral lymph nodes.

Specifically, I do t understand what it means about the bilateral lymph nodes. The person doing the ultrasound was very quick and even said that the 12mm lymph node was now 11mm. I have no other symptoms except for slight discomfort (no pain) in the right groin area.
