Most frequently, the lung abscess arises as a complication of aspiration pneumonia caused by mouth anaerobes. Univariate and multivariable analyses were performed with the Cox proportional hazards model to determine predictors of risk for recurrent disease. The Gram stain showed Gram positive cocci in clusters. Most often, this occurs between the internal and external sphincters (intersphincteric abscess), where the perianal glands are located. Multiple small abscess formation may occur and is sometimes referred to as necrotising pneumonia. Common sites affected include the armpits and inner thigh (groin), called hidradenitis suppurativa, also known as acne inversa (AI). As a ligament injury was suspected, T2-weighted images (Figure 1) showed extensive intramuscular fluid within the adductor and hamstring muscle groups, and intramuscular edema within the quadriceps muscle.
If your skin abscess needs draining, you will probably have a small operation carried out under
