Chylous pericardial effusion is a rarely reported complication of lung cancer surgery. Here, we report a case of an elderly man who suffered chylous pericardial effusion after radical right upper lung resection for cancer. The massive chylous effusion first occurred in the pericardium, drained to the right chest after the drainage of the hydropericardium and subsequently moved back to the pericardium again. Lymphoscintigraphy examination indicated that a chylous fistula was present in the plane of the tracheal carina...

In prostate cancer, reliable information about the lymph node status is of great importance for accurate staging and the optimal planning of treatment. Despite recent advances in imaging, the histological detection of metastases, or pelvic lymphadenectomy (PLND), continues to be the most reliable method for lymph node staging in clinically localised prostate cancer, especially as this procedure enables the detection of small or micrometastases. Radioisotope-guided sentinel PLND (sPLND) demonstrates high sensitivity in the detection of lymph node metastases as well as low morbidity in prostate cancer because of the targeted removal of a relatively small number of lymph nodes...

INTRODUCTION: Aberrant, altered, or blocked lymphatic drainage may contribute to the high recurrence rate of breast cancer. Thus, an efficient evaluation of lymphatic drainage from the breasts and/or upper limbs is essential in the management of lymphedema and in ipsilateral primary or contralateral recurrent breast cancer patients. There are very few reports of lymphatic drainage to the paravertebral lymph nodes in patients with a lymphedema after breast cancer surgery with or without reconstruction...

Chyluria implies an abnormal communication between the lymphatic system and the urinary tract. It is more frequent in endemic areas of lymphatic filariasis, which constitutes the main cause. Chyluria may mimic a nephrotic syndrome. Diagnosis of chyluria is based on urinary cytological and biocheminal analysis. Localization of the fistula needs medical imaging: cystoscopy, retrograde pyelography, lymphoscintigraphy and more recently magnetic resonance lymphography. Due to frequent spontaneous remissions, traitement can require only dietary measures...

We describe the lymphoscintigraphy findings of a 25-year-old female patient who was undergoing presurgical workup for lymphangiomas of the vulva. She had a history of treatment for disseminated tuberculosis 6 years back and presented with herpetiform oozing vesicles in the external genitalia. Single-photon emission computed tomography/computed tomography (SPECT/CT) confirmed cutaneous tracer accumulation in the vulval lesions and demonstrated the presence of densely calcified inguinal nodes secondary to healed tuberculosis as the etiology of secondary lymphangioma...

OBJECTIVE: Currently, lymphedema (LED) is typically diagnosed clinically on the basis of a patient's history and characteristic physical findings. Whereas the diagnosis of LED is sometimes confirmed by lymphoscintigraphy (LSG), the technique is limited in both its ability to identify disease and to guide therapy. Recent advancements provide opportunities for new imaging techniques not only to assist in the diagnosis of LED, based on anatomic changes, but also to assess contractile function and to guide therapeutic intervention...

PURPOSE: Currently, most centres use 2-D planar lymphoscintigraphy when performing dynamic sentinel lymph node biopsy in penile cancer patients with clinically impalpable inguinal nodes. This study aimed to investigate the role of SPECT/CT following 2-D planar lymphoscintigraphy (dynamic and static) in the detection and localization of sentinel lymph nodes in the groin. METHODS: A qualitative (visual) review was performed on planar followed by SPECT/CT lymphoscintigraphy in 115 consecutive patients (age 28-86 years) who underwent injection of (99m)Tc-nanocolloid followed by immediate acquisition of dynamic (20 min) and early static scans (5 min) initially and further delayed static (5 min) images at 120 min followed by SPECT/CT imaging...

Over the past 2 decades, lymphoscintigraphy and sentinel node biopsy have become widely accepted and are used by surgeons to stage many solid cancers, especially breast cancer. However, despite growing experience, there are a number of unresolved issues. In addition, the impact of a new radiopharmaceutical remains to be determined. The present article addresses some of these issues (either unresolved, recurrent, or newly emerged), with a focus on the properties of radiopharmaceuticals used for sentinel node mapping in breast cancer...

PURPOSE: To assess the role of single-photon emission computed tomography with computed tomography (SPECT-CT) for the identification of sentinel lymph nodes (SLNs) in patients with early stage (T1-T2) oral cancer and a clinically negative neck (cN0). METHODS: In addition to planar lymphoscintigraphy, SPECT-CT was performed in 66 consecutive patients with early stage oral cancer and a clinically negative neck. The addition of SPECT-CT to planar images was retrospectively analyzed for the number of additional SLNs, more precise localization of SLNs, and importance of anatomical information by a team consisting of a nuclear physician, surgeon, and investigator...

Secondary lymphedema is still a worldwide problem. Symptomatic approaches to lymphedema therapy have been mainly used, with complete decongestive therapy as the cornerstone. Due to a lack of regenerative therapy, researchers have established various animal models to obtain insights into pathomechanisms and to reveal the best therapeutic option. Since the first reproducible and reliable animal model of lymphedema was reported in dogs, the technique of circumferential excision of lymphatic tissue has been translated mainly to rodents to induce secondary lymphedema...

The aim of this study was to review the outcomes of a series of breast cancer patients who underwent sentinel node biopsy inclusive of lymphoscintigraphy, and to assess the incidence of internal mammary node (IMN) metastatic positivity at exploration and whether these findings influenced treatment. Between April 2001 and December 2012, 581 breast cancer patients at Princess Alexandra Hospital underwent preoperative lymphoscintigraphy in the course of the performance of sentinel node biopsy. Analysis was performed of those patients who demonstrated radio-isotope uptake to the IMN chain, and who had sentinel node biopsy of the IMN's and were found to have metastatic involvement...

BACKGROUND: The presence of nodal metastases is the single most important prognostic factor in penile cancer. However, reliable assessment of nodal status in clinically node-negative (cN0) patients poses a challenge. Approximately 20% of these patients harbour occult nodal metastases. Currently available non-invasive radiological investigations are unreliable in excluding micrometastatic disease. AIM: Dynamic sentinel node biopsy (DSNB) is a minimally invasive procedure for assessing lymph node involvement...

A 58-year-old woman with previous right breast carcinoma treated with lumpectomy, right axillary clearance, chemo-radiotherapy, and adjuvant hormonal therapy underwent a lymphoscintigraphy for a new right breast lesion. On planar images, an alternate route of lymphatic drainage was observed to the right internal mammary chain and the left axilla. A chest SPECT/CT was performed to confirm the location of the sentinel nodes. The patient underwent a right mastectomy and left axillary sentinel lymph node biopsy, which showed no evidence of lymphovascular invasion...

Lymphoscintigraphy has introduced with the great advantage for diagnostic imaging of the lymphatic flow disorders. Lymphoscintigraphy can be performed in patients of any age, including neonates, and even in patient in critical conditions. The procedure is quite simple, and it needs only subcutaneous injection of small amounts of radiotracers. From subcutaneous tissue the radiotracer is taken by the lymphatic vessels and gives off energy in the form of gamma radiation detected by a gamma camera. Radiotracers rarely cause the allergic reaction and can be administered to the patients with allergy to iodine contrast media...
