CASE STUDY

Dr. Muhammad Umar TauqirMCPS Trainee

Al.Noor Diagnostics

• A man 38 years old presented in Al.Noor diagnostics on 14th Jan 2014 with history of fall 3-4 moths back. He has severe back pain radiating to the leg. Patient also experienced difficulty in standing from sitting position.

• There is history of intermittent fever for last 3-4 months.

• Patient is not diabetic or hypertensive • There is positive family history of tuberculosis as well

• He was advised MRI scan of L/S spine

• MRI reporting of patient reveals that patient Is suffering from tuberculous spondylitis with Psoas abscess

• Potts disease is also known as tuberculous spondylitis usually secondary to extra spinal source of infection. It usually occurs as combination of osteomylitis and arthritis that usually involves more than one vertebrae. The anterior aspect of vertebral body adjacent to the subchondral plate is usally affected. Progressive bone destruction leads to vertebral collapse and kyphosis as well

• T1 weighted images demonstrates difference in t1 relaxation time of tissues

• A t1 weighted image relies upon the longitudnal relaxation of the tissue net magnetization vector

• E.g fat quikly allign itself on t1 weighted image and therefore it appears bright

• T2 weighted images relies upon the tranverse relaxation of net magnetization vector

• The amount of t2 decay a tissue experience depend on multiple factors. Each tissue has its own inherent t2 value but external factor such as magnetic field inhomogenity canincrease the t2 relaxation of tissues as well
