An Unusual Case of Lumbar Hernia through Petit's Triangle

spleen?not palpable. Heart and lungs?nothing abnormal detected. Local?a hemispherical swelling 6 inches in diameter situated in the back of the right lumbar region over the triangle of Petit extruding above to the last rib, below to the upper part of the gluteal region (2 inches below the iliac crest), medially to near the middle line, and laterally to the right anterior axillary line. It has a fairly well-defined outline except anteriorly (figure 1, plate XIII). It increases in size on coughing with expansile impulse and diminishes when the patient lies on the left side, and is fully reduced on pressure. The swelling feels soft and boggy through which coils of intestine can be felt. Margins of the Petit's triangle are very well-felt and the gap admits 3 fingers deep into it. The swelling is tympanitic on percussion.
