RESUMO
When intestinal obstruction presents with fluid-filled bowel loops instead of air-distended loops, subtle elongated masses representing these bowel loops may be missed on plain abdominal radiographs. In these cases, ultrasound will show sausage-shaped, cystic structures, with uneven margins representing mucosal folds, distributed throughout the abdomen and sometimes accompanied by peristalsis. These features differentiate fluid-filled bowel loops from other cystic structures in the abdomen and help make a diagnosis of bowel obstruction.

A chronic ectopic pregnancy is a form of tubal pregnancy in which there is gradual disintegration of the tubal wall with slow and/or repeated episodes of hemorrhaging leading to the formation of a pelvic mass. A review of 22 pathologically proven cases of this entity revealed the pelvic mass to be a hematocele, or a sealed-off inflammatory mass composed of blood clots, organized hematomas, and surrounding adhesions. Sonographically, the abnormality is manifested by an extrauterine, complex mass in the adnexa(e) and cul-de-sac. The mass may obliterate uterine margins and be confused for pelvic inflammatory disease, endometriosis, or uterine leiomyomas. With an increased awareness of this entity and its mildly symptomatic and protracted clinical course, a preoperative diagnosis should be possible.

A case of diffuse osseous tuberculosis with changes on skeletal Tc-99m methylene diphosphonate (MDP) and indium-111 chloride scintigraphy is presented. Only two other cases of bone scan findings in osseous tuberculosis (TB) were reported in the literature and both show patterns similar to diffuse metastatic disease. In addition, the demonstration of corresponding areas of decreased tracer activity on indium-111 bone marrow scintigraphy is a finding that has not been previously reported for skeletal tuberculosis.
