Knee pain is a very common clinical complaint, especially among active individuals. 2. 4 (3): 257-72. MRI helps in treatment decision making, as was demonstrated in our case, in which the ganglion cyst was large and was located outside the synovium but within the fat pad. 4. reported a ganglion cyst arising from the infra-patellar fat pad of a 10-year-old boy . Draghi F, Ferrozzi G, Urciuoli L, Bortolotto C, Bianchi S. Hoffa's fat pad abnormalities, knee pain and magnetic resonance imaging in daily practice. (1997) AJR. It measures 3.1 x 2.5 x 1.5 cm in its maximal diameter. The fat pad has abundant nerve innervation, which makes it one of the most pain-sensitive structures in the knee. Perdikakis E, Skiadas V. MRI characteristics of cysts and "cyst-like" lesions in and around the knee: what the radiologist needs to know. Hoffa’s fat pad contains residual synovial tissue, meaning that primary neoplastic conditions of synovium may originate and be confined to the fat pad. Miljko M, Markotić V, Huseinbegović A, Kapur E, Marijanović I, Jurić I. 6. The medial fat pad shows normal signal intensity. Krudwiget and al. Due to non-specific symptoms, 2,7 proper management is usually delayed. Management options depend vastly on clinical symptoms and include conservative measures, image-guided percutaneous aspiration as well as arthroscopic or surgical excision 2,4-6. This patient”s findings suggest it is probably the largest Hoffa's fat pad ever to be published in the literature. Giant infrapatellar ganglion cyst of Hoffa's fat pad. Purpose: To investigate efficacy and safety of ultrasonography-guided local corticosteroid and anesthetic injection followed by physical therapy for the management of quadriceps fat pad (QFP) edema.

Numerous traumatic and non-traumatic processes may be encountered, many occurring relative to the anterior compartment, including impingement or friction syndromes. Ganglia within Hoffa’s fat pad can be asymptomatic or can cause pain and swelling or present as a palpable mass 1,2. Most of them originated from the anterior or posterior cruciate ligament. 13 Issue 1, p1 . One study showed that areas of signal change in the fat pad on T1-weighted spin-echo or T2-weighted gradient-echo unenhanced images correlate histologically with mild chronic synovitis in the same location [ 2 ]. Kager's fat pad, also known as the pre-Achilles fat pad, is a lipomatous structure located in the posterior ankle joint, anterior to the Achilles tendon. 5, 6, 7 It is more commonly noticed in young age group and male patient. Ganglion cysts within Hoffa’s fat pad are usually well-defined, smooth-walled, uni- or multilocular, lobulated cystic masses surrounded by dense connective tissue and filled with viscous, mucinous material like other ganglion cysts. Hoffas fat pad contains residual synovial tissue, meaning that primary neoplastic conditions of synovium may originate and be confined to the fat pad. In contrast, only three cases originated from the infra-patellar fat pad . In addition, the infrapatellar fat pad may be involved secondarily from extrinsic processes, including articular disorders (eg, joint effusion, intraarticular bodies, meniscal cyst, ganglion cyst, cyclops lesion), synovial abnormalities (eg, …
