Abdominal imaging

Chronic anoperineal pain without any apparent etiology may be caused by compression of the pudendal nerve. This presentation illustrates the course of the pudendal nerve and the technique of computed tomography-guided infiltration of the nerve.

To describe the spectrum of imaging findings and clinical presentations produced after rupture and hemorrhage of an ovarian cyst. ⋯ A ruptured ovarian cyst can produce massive hemoperitoneum, with clinical symptomatology and sonographic features that closely mimic those of other disorders, in particular ectopic pregnancy. Considering the likelihood of both clinical and radiologic misdiagnosis, the radiologist should consider and pursue the diagnosis of a ruptured hemorrhagic ovarian cyst in a woman of child-bearing age who presents with pelvic pain and a large amount of complicated intraperitoneal fluid.

Epiploic appendagitis is a self-limiting disease. Depending on its location, it may simulate nearly any acute abdominal condition. ⋯ We describe a patient with acute abdominal pain in the right lower quadrant, in whom the combination of an old and fresh infarction of an epiploic appendage simulated appendicitis on ultrasound. Subsequent CT examination made the correct diagnosis.

Comparative Study
T2-weighted MR imaging for hepatic hemangiomas: comparison of breath-hold and non-breath-hold turbo spin-echo pulse sequences with phased-array multicoil.
We compared T2-weighted and heavily T2-weighted breath-hold turbo spin-echo (TSE) sequences with T2-weighted non-breath-hold TSE sequence to evaluate hepatic hemangiomas on magnetic resonance (MR) with a phased-array multicoil. ⋯ T2-weighted breath-hold TSE sequence is superior to T2-weighted non-breath-hold TSE sequence in the evaluation of hepatic hemangiomas on MR with a phased-array multicoil.

We report the case of a 29-year-old man with a long-standing history of abdominal pain related to an intermittent colocolic intussusception caused by pneumatosis cystoides coli. To our knowledge, only one similar case has been reported in the English-language literature.
