Female 55 years old Reason: please rule out abscess on the back of head History: patient with indurated lesion on back of scalp unclear if abscess In the area of the palpable lump there is a small hypoechoic area ill-defined measuring 0.4 x 0.4 x 0.2 cm of uncertain significance. Does not have increased through transmission to suggest a fluid collection. Possibly lymph node. Abscess cannot be excluded but is unlikely.
Small nonspecific irregular hypoechoic focus in the palpable region.
