Pituitary incidentalomas detected with technetium-99m MIBI in patients with suspected parathyroid adenoma: preliminary results.

Tc-99m MIBI (MIBI) is a cationic lipophilic agent, which has traditionally been used for myocardial perfusion scintigraphy, detection and monitoring of different benign and malignant tumors. The objective of this study was to evaluate the frequency of pituitary incidentalomas detected on MIBI scans performed on patients with suspected parathyroid adenomas and to provide semiquantitative analysis of tracer uptake in the pituitary region. Tomographic images of MIBI scans on 56 patients with suspected parathyroid adenomas (2006-2007) were analyzed retrospectively.

Tc-99m methoxyisobutylisonitrile parathyroid scintigraphy: the value of adding a whole-body scan.

Purpose: The aim of this study was to estimate the frequency of incidental findings on Tc-99m-methoxyisobutylisonitrile (MIBI) scan performed for suspected parathyroid adenoma and to evaluate the benefit of additional whole-body scan.

Materials And Methods: A total of 109 patients (37 men and 72 women; age range, 16-96 years; mean, 58.42 years) with clinically suspected parathyroid adenoma underwent Tc-99m MIBI whole-body scans and single-photon emission computed tomography of the base of the skull, the neck, and the thorax.

Unilateral urinothorax due to nephropleural fistula detected on Tc-99m diethylenetriamine pentaacetic acid renal scintigraphy.

Urinothorax or urothorax, the presence of urine in the pleural space, is a rare complication of percutaneous access to the kidney for the management of complex renal and proximal ureteral calculi and ureteropelvic junction obstruction. Other causes such as blunt renal trauma, ureteral instrumentation, or ureteral surgery have also been reported. The authors describe a patient with a massive left pleural effusion with total lung atelectasis.

Intramuscular metastasis of carcinoid tumor: a rare manifestation.

A 43-year-old man presented with a 2-month history of left upper lobectomy due to an atypical lung carcinoid tumor. The patient was referred to our department for further evaluation. An In-111 octreotide (Octreoscan) whole body scan and single photon emission computed tomography were performed.

Leukocyte scintigraphy SPECT/CT software fusion diagnosis of infected gastric band.

The prevalence of morbid obesity is increasing worldwide and presents a significant clinical problem. Laparoscopic adjustable gastric banding has been popularized as an effective, safe, minimally invasive surgical technique for the treatment of morbid obesity. Different diagnostic imaging modalities are crucial for follow-up of "banded" patients and detection of the different postoperative complications.

Unilateral Tc-99m pertechnetate breast uptake: is it always benign?

Although the thyroid gland is the principal organ with the ability to concentrate iodide and take up Tc-99m pertechnetate, other tissues such as choroid plexus, salivary glands, mucoid cells of stomach, and lactating breast tissue also possess this property. The lactating mammary gland can concentrate iodide, which mediated by sodium/iodine symporter (NIS) is actively transported and secreted in the milk, to supply iodide to the newborn for the biosynthesis of thyroid hormones. The authors present an uncommon case of unilateral Tc-99m breast uptake in a breast-feeding woman.

The usefulness of Tc-99m-HMPAO-labeled leukocyte scintigraphy in the diagnosis of multiple intra-abdominal abscesses following in vitro fertilization (IVF) procedure.

Pelvic infection is a rare but well-known complication following IVF procedures with a reported incidence <1%. A case of multiple abdominal abscesses following IVF procedure was established by Tc-99m-HMPAO-labeled leukocyte scintigraphy and confirmed by laparotomy. This imaging technique should be recommended for early and precise diagnosis of pelvic infection following IVF.

Is osteoid osteoma an iodophilic lesion?: pathologically proved osteoid osteoma of nasal bone first seen on whole-body iodine-131 scan.

The authors present a case of pathologically proved osteoid osteoma that was visualized randomly on an I-131 whole-body scan. Search of the medical literature did not reveal any mention of radioactive iodine uptake by osteoid osteomas. Therefore, the authors concluded that this pathology must be included in the differential diagnostic list of positive findings on I-131 scans.
