Anatomic correlations in radiogallium imaging of the peritoneum and retroperitoneum.

Radiogallium (67Ga) imaging of the abdomen and pelvis has been useful not only in detecting inflammations in these regions, but in pointing out their precise anatomic localization. Once the anatomic site is determined, it is often possible to infer the source of origin of the problem (such as ruptured viscus or pancreatitis). Interpretation of the images depends on recognition of patterns that define known anatomic boundaries such as the transverse mesocolon, root of the small mesentery, perirenal space, and pararenal space, or else show diffuse peritoneal uptake. The anatomic patterns may have continued usefulness in future studies, such as when radiolabeled leukocytes are employed to localize inflammations.

67Ga-citrate identification of inflammation in the perirenal space.

Two patients are presented who had radiogallium (67Ga-citrate) studies which revealed focal abdominal accumulations identified as the perirenal space. These localizations, to a specific anatomical site, were confirmed surgically. The distinguishing features of the perirenal space on radiogallium scans include the relatively vertical axis, downward conical extension, and sharp cut-off ("sparing") medially to the midline.

Colonic lymphangioma.

Eleven cases of colonic lymphangioma, including 3 that have not been reported previously, are reviewed. Radiologic analysis reveals that 9 presented as polypoidal mucosal lesions and only 2 had characteristic features at a submucosal lesion. A predominant occurence in females (70%) and during the sixth and seventh decades are noted.

Drowning: another plunge.

Hypoxia, pulmonary edema, acidosis, and aspiration compose the syndrome of near drowning. A review of 20 cases of near drowning indicated that the initial chest roentgenogram bears little weight in assessing the present or future clinical status. In some cases a 24 to 48 hour delay occurred before roentgenographic evidence for pulmonary edema was noted. The composition of fluid aspirated does not affect the outcome. The results of this report suggest that patients with a history of near drowning should be followed closely for at least 48 hours despite an initial normal chest roentgenogram.

Antral infracolic volvulus of the stomach.

Two cases of antral infracolic volvulus of the stomach are presented. The etiology of gastric volvulus and the difference between the organo-axial and mesentero-axial volvulus are discussed. Further subdivision into partial or complete volvulus and the relationship between the transverse colon and the stomach during gastric volvulus is emphasized. Awareness and understanding of gastric volvulus may allow roentgen diagnosis.
