Anal gland infections most commonly lead to perianal fistulas. With advances in techniques, MR imaging has proven to play an important role in perianal fistula evaluation and is currently considered to be the gold standard. This was a hospital based prospective observational study in which around 100 patients who were diagnosed to have perianal fistula clinically and referred for MR fistulogram to the Department of Radio diagnosis & Imaging, Government Medical College, Srinagar, J&K, India and were included in the study. In this study we concluded that about 26% patients (26 out of 100) had secondary tracks and 31% (31 out of 100) had associated abscesses which showed 86% concordance with surgical findings.

Common variable immunodeficiency is characterized by decreased levels of immunoglobulins leading to repeated infections of chest, gastrointestinal tract, etc., Radiological findings and clinical suspicion could be helpful in diagnosing common variable immunodeficiency thereby decreasing mortality and morbidity associated with disease. We present radiological findings in a 20-year-old patient with laboratory findings supporting the diagnosis of common variable immunodeficiency.

Contrast-enhanced magnetic resonance angiography is a valuable technique in the assessment of vascular anomalies of the lower limb. This is an ideal investigation in children and young adults as it is non-invasive and poses no radiation risk. We present a series of cases to highlight this.
