Transient intussusception without a lead point in adults — a rare condition or a silent cause of common symptoms?

Streszczenie

Bowel intussusception is a rare condition in adults. Two types of intussusception determine its cause —
with and without a lead point. The former, resulting from an organic cause is more common in adults
and usually requires surgical treatment. The symptoms of intussusception include abdominal pain, nausea,
vomiting and gastrointestinal obstruction. Additional symptoms may be due to the presence of the
pathology that constitutes the lead point of intussusception, such as a tumour or inflammatory intestinal
disease. On diagnostic imaging, intussusception appears as a target-sign or sausage-shaped mass. Due
to the rare occurrence of intussusception in adults, special attention should be paid to detecting the underlying
organic causes of its occurrence. Transient intussusception is generally a non-lead point, occurs
incidentally and is not life-threatening. Non-diagnosed periodic abdominal pains in adults can be caused
by a transient intussusception of the small bowel. The article presents and discusses two cases of a rare
transient non-lead point intussusception that was diagnosed during a CT which subsided or occurred
during the consecutive phases of this examination.
