  6. STIR Sagittal Right Leg 35F. History of right leg mass for 8 years. Increased size of mass after bumping it recently

  7. Tibialis Anterior Herniation • Most common muscle herniation – EDL, PB,PL, and gastrocnemius reported • Result of local blunt trauma, penetrating injury or muscle hypertrophy • Complications rare – muscle necrosis secondary to strangulation • Fascial defect cannot always be seen on imaging

  8. Wendy McCurdy 16 year old girl History-recent onset pain in the region of the first metacarpal joint

  9. CT Left hand/Thumb 16 year old girl. History-recent onset pain in the region of the first metacarpal joint

  10. T1 Axial Left Hand/Thumb 16 year old girl. History-recent onset pain in the region of the first metacarpal joint

  11. T1 Coronal Left Hand/Thumb 16 year old girl. History-recent onset pain in the region of the first metacarpal joint

  12. T2 FS Coronal Left Hand/Thumb 16 year old girl. History-recent onset pain in the region of the first metacarpal joint

  13. Acute Sesamoiditis of the Thumb • In fractures ulnar sesamoid affected 3:1 to radial sesamoid • Degenerative changes more commonly involves the radial sesamoid

  14. Wendy McCurdy • 79 year old male • History of ankle pain

  15. T1 Axial Left Ankle 79 year old male History of ankle pain

  16. T2 FS Left Ankle 79 year old male History of ankle pain

  17. Synovial Chondromatosis • Etiology – proliferative and metaplastic changes in the synovium resulting in multiple cartilaginous nodules - variable calcification/ossification • Presents third to fifth decades M>W • Knee, hip and ankle joints most commonly involved • Treatment - surgery

  19. Glenn Garcia •  21 y/o male tuberous sclerosis : right knee mass.

  20.  21 y/o male tuberous sclerosis : right knee mass. PF: Infrapatellar non-mineralized soft tissue mass.

  21. MR: T1, PD, Post Gd imaging show an infrapatellar lobulated low signal lesion containing mildly enhancing septa and scattered foci of fat.

  22.  21 y/o male tuberous sclerosis : right knee mass. • DDX: • Localized PVNS • Synovial hemangioma • Tophaceous deposit

  23.  21 y/o male tuberous sclerosis : right knee mass. • DIAGNOSIS: • SYNOVIUM, RIGHT KNEE, EXCISION:- BENIGN ANGIOFIBROLIPOMA   NO EVIDENCE OF MALIGNANCY  

  24. This lesion is most likely related to pt’s h/o TS. The prominent expression of the fibrous component of this lesion is represented by the low signal on MRI. Variations of this lesion have been well described in the kidney, heart, spleen, lungs and GI tract of TS patients. Benign Angiofibrolipoma

  25. Glenn Garcia • 54 y/o dx’d with HIV x 3yrs with 1 mos h/o knee pain, no h/o surgery or trauma.

  26. 54 y/o dx’d with HIV x 3yrs with 1 mos h/o knee pain, no h/o surgery or trauma. Current Meds-Lopinavir, Ritonavir

  27. Diffuse PD and T2 signal increase is localized to the infra-patellar fat with no other abnormality identified. 54 y/o dx’d with HIV x 3yrs with 1 mos h/o knee pain, no h/o surgery or trauma.

  28. Inflammation of Hoffa’s fat pad-”Hoffitis” 54 y/o dx’d with HIV x 3yrs with 1 mos h/o knee pain, no h/o surgery or trauma.

  29. MR imaging findings of diffuse inflammation of Hoffa’s fat pad are nonspecific and unclear in etiology, an association with HIV and/or anti-viral meds may exist. 54 y/o dx’d with HIV x 3yrs with 1 mos h/o knee pain, no h/o surgery or trauma.

  39. D: Calcific Retropharyngeal Tendinitis Ring D, Vaccaro AR, Scuderi G, Pathria MN, Garfin SR. Acute calcific retropharyngeal tendinitis.JBJS Am 1994;76:1636–42 • Acute calcific retropharyngeal tendinitis • (Syn: Acute calcific prevertebral tendinitis) • Foreign-body inflammatory response crystals of hydroxyapatite • Insertion of longus colli (Anterior arch of C1) • Symptoms: Severe neck pain, pain on swallowing, reduced range of motion of the neck. • Clinical presentation similar to calcific tendinitis elsewhere. • Self-limiting, (NSAID), symptoms disappear within 1 week. • Calcification slowly resolves after a period of 2–3 months.
