Giant splenic hemangioma: confirmation of diagnosis with labeled erythrocyte scintigraphy

Licht, M; Goffner, L; Yung, E; Hon, M; Katz, DS
PURPOSE: To assess the use of a Tc-99m erythrocyte-labeled SPECT scan to characterize a giant splenic hemangioma. METHODS: A patient clinically mistaken to have a myelodysplastic disorder underwent a contrast-enhanced CT followed by a Tc-99m erythrocyte-labeled SPECT scan. RESULTS: CT showed a heterogeneous vascular lesion arising in the spleen. Percutaneous biopsy was nondiagnostic. A Tc-99m erythrocyte-labeled SPECT study revealed findings consistent with a giant splenic hemangioma, which was subsequently confirmed at surgery. CONCLUSION: A Tc-99m erythrocyte-labeled SPECT scan may be very useful in confirming the diagnosis of a large or giant splenic hemangioma.

Splenic vein aneurysm: is it a surgical indication? [Case Report]

Torres, G; Hines, G L; Monteleone, F; Hon, M; Diel, J
Splenic vein aneurysms are rare and are usually caused by portal hypertension. Symptoms are unusual, but may include rupture or abdominal pain. Diagnosis can usually be made either by means of duplex ultrasonography or computed tomography scanning. Treatment varies from noninvasive follow-up to aneurysm excision. We report an expanding splenic vein aneurysm in a young woman with abdominal and back pain and no history of portal hypertension. She was treated with aneurysm excision and splenectomy.

Fine-needle aspiration as the initial diagnostic modality in malignant lung disease

Blumenfeld, W; Singer, M; Glanz, S; Hon, M
Cytologic detection of lung cancer is accepted, accurate, and time-honored. Typically, cytologic workup of a radiologic abnormality proceeds sequentially from sputum to bronchoalveolar cytology, and, if necessary, to fine-needle aspiration biopsy (FNA). Initial use of FNA in lung cancer diagnosis is controversial, but increasingly popular. We therefore decided to objectively assess current practice in cytologic lung cancer diagnosis at our institution. All pulmonary cytologic diagnoses for 1993 and the first half of 1994 were retrieved. Positive diagnoses were then used to access all patient data. Patients were stratified according to the specimen from which the first positive diagnosis was obtained. Of 542 pulmonary cytology specimens, 15% were sputa, 65% were bronchoalveolar, and 20% were FNAs. One hundred sixty-one of 172 malignant diagnoses were first diagnoses. Three percent of first malignant diagnoses were made from sputa, 47% were from lavages, and 50% were from FNAs. Although FNAs comprised just 20% of all pulmonary cytologies, 50% of all new malignant cytologic diagnoses were made by FNA. Initial use of FNA is successful, has a high diagnostic yield and low complication rate, and offers the most direct approach to diagnosis.
