RESUMEN
We report herein the case of a ruptured liver abscess that resulted in pneumoperitoneum. A patient with diabetes mellitus presented with symptoms of acute abdomen. The plain abdominal radiograph and computed tomography findings revealed abdominal free air and a gas-containing liver abscess, whereby a diagnosis of a ruptured liver abscess was made. An emergency operation was performed, and the abscess was drained followed by peritoneal lavage and the administration of appropriate antibiotics. To the best of our knowledge, very few cases of spontaneous pneumoperitoneum occurring secondary to the rupture of a gas-containing liver abscess have been encountered in Japan.

We presented three patients with bilateral breast tumors (one with breast cancers, one with breast cancer and fibroadenoma, and one with fibroadenomas) examined by 99mTc-hexakis 2-methoxy-isobutylisonitrile (MIBI) scintimammography. In all cases 99mTc-MIBI uptake was recognized only in the breast cancers. 99mTc-MIBI scintimammography was useful in evaluating bilateral breast tumors since preoperative diagnosis is valuable in determining correct surgical treatment.

We presented two cases of phyllodes tumor of the breast examined by 99mTc-sestamibi (MIBI) two-phase scintimammography. In the case with malignant phyllodes tumor, 99mTc-MIBI accumulation was recognized on both early and delayed images. In the case with benign phyllodes tumor, however, 99mTc-MIBI accumulation was recognized on only the early image. 99mTc-MIBI delayed imaging may have the potential to distinguish between benign and malignant phyllodes tumors.

We report a case of a giant malignant phyllodes tumor examined by(99m)Tc-ses-tamibi (MIBI) mammoscintigraphy. The patient was a 51 year-old woman who complained of bleeding from a large mass in her right breast. The tumor was well circumscribed, with an ulcerized surface. The accumulation of(99m)Tc-MIBI in the tumor was recognized on(99m)Tc-MIBI scintigraphy. A standard radical mastectomy was performed with a wide margin of skin. The resected specimen measured 20 X 17 X 13 cm, weighed 2100 g and was histologically diagnosed as a malignant phyllodes tumor. The skin defect was reconstructed by a rectus abdominis musculocutaneous flap, with good cosmetic results.(99m)Tc-MIBI scintigraphy may have the potential to distinguish a malignant from benign phyllodes tumors.

RESUMEN
Primary splenic tumors are very rare. The authors present a case of splenic hamartoma in which positive 99mTc-DTPA-HSA uptake was recognized with ultrasound, CT, MR and angiographic images. This case showed the need to consider hamartoma as well as hemangioma in the differential diagnosis of 99mTc-DTPA-HSA uptake in splenic tumors.

We report a case of sigmoid colon cancer in which visualization of an appendiceal mucocele was unexpectedly found during 67Ga scintigraphy, and discuss a proposed mechanism of uptake.
