[Scintigraphy in the diagnosis of visceral candidiasis]. / Apport de la scintigraphie au diagnostic des candidoses viscérales.

From the features of two cases, the authors stress the usefulness of the scintigraphy as regards to the diagnosis of visceral candida abscesses. Such fungal localisations are not infrequent, especially in immunodeficient patients (haematologic malignancies undergoing chemotherapy, lupus, serious visceral illness...). The positive diagnosis is uneasy because of non-specific clinical features and frequent negative blood cultures. Splenic localisation is the most likely. Citrate Gallium scintigraphy together with splenic labeled RBC scan enables us to give a precise view of the splenic involvement and even of the abdominal extension of the fungal abscess. From the literature review and these two cases, the excellent adequacy of the scintigraphy to the follow-up of systemic candidiasis is underlined and is compared to other usual morphological studies such as US scan and CT examination. In both cases, the diagnosis is fully confirmed by mycological examination.

[Scintigraphy in the evaluation of painful arthroplasties. Simultaneous use of technetium and gallium]. / Scintigraphie dans le bilan des arthroplasties douloureuses. Utilisation simultanée du technetium et du gallium.

Fifty-nine patients with 60 painful hip arthroplasties were assessed by scintigraphy using M.D.P. 99m Te and 67 Ga bone scanning. The M.D.P. 99m Te bone scanning was very reliable with 100 p. 100 of positive results. However, it did not elucidate the cause of the pain. Sixty-seven Ga scanning, when positive, allowed the diagnosis to be orientated towards an infective cause. However in 6 out of 18, the scanning was negative despite a proved infection. The technical details are described by which quicker and safer results can be obtained.

[Results of scintigraphy with m-[123I]iodobenzylguanidine in neuroblastoma in children]. / Resultats de la scintigraphie à la m-[123I]iodobenzylguanidine dans le neuroblastome de l'enfant.

From 46 [123I]m IBG scans performed in 33 children, excellent specificity (96%) and good sensitivity (90%) appeared in the detection of neuroblastoma; less differentiated non catecholamine-excreting tumours remained undetected. As any localization to be seen was clearly visualized on the 24-h scan, the use of the [123I]m IBG (p, 5n) is recommended for the diagnosis, staging and follow-up of neuroblastoma in children.

Use of pertechnetate 99mTc for abdominal scanning in localising an ileal duplication cyst: case report and review of the literature.

A 10-year-old boy presented with periumbilical postprandial pain and some melena. Physical examination was normal. All investigations were negative except a pertechnetate 99mTc abdominal scan which showed a very large and horn-shaped focus of high activity in the right flank. An ileal duplication was resected. It was lined by antral gastric mucosa with a large ulcer. The patient was treated successfully. The abdominal pertechnetate scan is discussed.
