These are images on a 31 year old woman who is presenting with
0:05
palpable abnormality along the dorsal aspect of the wrist.
0:10
On Axi T one weighted images,
0:12
we see a focal fluid collection that is extending between the second
0:17
and the third extensor compartment tendons emanating
0:22
from the dorsal mid carpal risk capsule and
0:27
extending into the subcutaneous tissues on fluid sensitive
0:31
sequence. This is a fat suppressed T two weighted image.
0:34
We can see the mass having very homogeneous fluid like signal
0:39
intensity with a very thin,
0:41
almost imperceptible peripheral capsule.
0:45
This is compatible with a ganglion cyst. Longitudinal images,
0:50
particularly the axial plane,
0:53
allow us to better describe the location of these, um,
0:57
ganglion pseudocyst. Uh,
0:59
it's a pseudocyst because there is no synovial lining.
1:02
What we have is connective tissue that has been created surrounding
1:07
these, um, focal fluid collection, uh,
1:11
which we can see now emanating from the dorsal, uh,
1:14
mid carpal region along the, uh,
1:17
capitated bone and extending between the extensor compartments to reach
1:22
the subcutaneous fat.

Report
Patient History
31-year-old female with possible mass or ganglion pseudocyst.
Findings
ALIGNMENT:
Ulnar Variance: Neutral.
Distal Radioulnar Joint: Normal.
Carpal Instability: Stable.
ARTICULATIONS:
Thumb Carpometacarpal Joint: Normal.
Scaphotrapeziotrapezoidal Joint: Normal.
Pisiform-Triquetral Joint: Normal.
Radiocarpal Joint: Normal.
Distal Radioulnar Joint: Normal.
Fluid: None.
Carpal Effusion: None.
Distal Radioulnar Joint Effusion: None.
INTRINSIC LIGAMENTS:
Scapholunate Ligament: Intact.
Lunotriquetral Ligament: Intact.
Triangular Fibrocartilage: The disc proper of the TFCC is intact. A small, lobulated cystic structure likely representing a capsulosynovial cyst is seen at the level of the meniscus homologous. The triangular ligament/ligamentum subcruentum is intact.
Lunate Facet: Normal.
Hamate-Lunate Facet: Normal.
Extensor Compartment: A well-circumscribed, dumbbell-shaped cystic structure measuring about 1.7cm x 1cm (transverse and CC diameters) is seen in the dorsal aspect of the wrist protruding through the extensor carpi radialis brevis and extensor pollicis longus tendon sheaths. No evidence of tendon tears or tenosynovitis.
Flexor Compartment: No flexor tendinopathy.
Carpal Tunnel: Normal.
Median Nerve: Normal diameter and signal intensity.
Flexor Retinaculum: Without thickening.
Guyon's Canal: No space-occupying lesions.
Impressions
1. A 1.7cm x 1cm dumbbell-shaped cystic structure in the dorsal aspect of the wrist protruding between the 2nd and 3rd extensor compartments in keeping with a ganglion pseudocyst.
2. Small, lobulated capsulosynovial cyst at the level of the meniscus homologous. The TFCC is otherwise intact.
