title: An atypical case of arising of some parietal branches of the Arteria iliaca interna in man.
abstract: In the pelvis of a 78 year old man there have been observed deviations in the origin and course os some parietal branches of the A. iliaca interna dextra. Apart from this typically arising and passing branches (the A. glutaea superior dextra, the A. glutaea inferior dextra, the A. umbilicalis dextra) an atypical stem--the Truncus pudendo-obturatorius--comes out of the A. iliaca interna dextra. This stem divides into the A. obturatoria dextra and the A. pudenda accessoria. The A. pudenda accessoria goes through the pelvis and through the fissure between Symphysis and the Diaphragma urogenitale on the Radix penis as the A. dorsalis penis dextra. The A. pudenda interna dextra comes out of the A. pudenda accessoria in a quite atypical way. It enters the fossa ischiorectalis through the fissure in the hind part of the Arcus tendineus m. levatoris ani ventrally from the Spina ischiadica. Its terminal part goes to the right Corpus cavernosum penis as the A. profunda penis dextra. The parietal branches of the A. iliaca interna sinistra arise and go in a typical way. The A. pudenda accessoria is not formed on the left side of the pelvis.
