2024年12月28日 · MRI is an accurate modality for the visualization and evaluation of ganglion cysts with a reported sensitivity and specificity of 94.7% and 94.4% 1,5. The typical appearance is that of a well-defined, multiloculated cystic lesion with a stalk. Spontaneous resolution occurs in up to 50% of cases.

2025年1月9日 · muscles: intramuscular ganglion cyst. menisci: intrameniscal ganglion cyst. tendons: intratendinous ganglion cyst 6. bones: intraosseous ganglion cyst. They most commonly (70-80% of cases) occur in relation to the hand or wrist (see ganglion cysts of the hand and wrist). In this location, notable specific subsites include 1:

Several processes can result in a mass, with or without pain, that can clinically mimic a dorsal ganglion cyst. MRI is useful in diagnosing these conditions. Extensor tenosynovitis can be related to overuse or may be a manifestation of a collagen vascular disease or primary arthritis such as rheumatoid arthritis.

2012年11月23日 · MRI is indicated in deep-seated cysts, when cysts show atypical features, or in specific preoperative settings. Fig. 1A — 42-year-old woman with palpable mass over wrist revealed to be typical cyst on ultrasound and MRI.

Ganglion cyst in the volar aspect of the wrist in a 55-year-old woman presenting with pain during volar flexion and paresthesia. Axial FS PD-weighted MRI ( a ) shows a smooth, multiloculated, homogeneously hyperintense lesion located deep and medial to the radial artery (arrow) and lateral to the flexor pollicis longus (dashed arrow) and the ...

Ganglion cysts are common hand masses. This article will answer three questions that the radiologist is often asked: A mass is palpable; is it a cyst? Pain or neurologic symptoms are present; are they related to a cyst? Surgery is being considered; where precisely are the cyst and its origin located? CONCLUSION.

Diagnosis of a ganglion cyst is largely clinical, but sometimes magnetic resonance imaging (MRI) or ultrasound is used for definitive diagnosis, or when the clinician is evaluating wrist pain of unknown etiology.

Magnetic resonance imaging (MRI) scans or ultrasounds. MRI scans and ultrasounds can better show soft tissues, like a ganglion, than X-rays. Sometimes, an MRI or ultrasound is needed to find an occult ganglion that is not visible, or to distinguish the cyst from other tumors. However, further imaging is often not needed prior to treatment.
