Apical hypertrophic cardiomyopathy (ApHCM) is a subtype of HCM. This variant is more common in the Asian population when compared to North American patients. Patients may present with arrhythmias, heart failure, myocardial infarction, chest discomfort, fatigue, and presyncope or syncope. Initial evaluation requires electrocardiogram and two-dimensional echocardiogram. T-wave inversion in the precordial leads as well as hypertrophy of the left ventricle is hallmarks of the disease. Cardiac magnetic resonance (CMR) imaging is the most specific and sensitive imaging modality...

Nuclear protein in testis (NUT) midline carcinoma (NMC) is a rare, aggressive, lethal, epithelioid, poorly differentiated cancer first described in Japan in 1991, unique in that is defined genetically rather than by histological tissue of origin. It usually arises in the body midline and presents as a mass with metastasis. An infant presenting with pneumonia was found to have a pericardial mass, NMC resected, and subsequent staging positron emission tomography (PET) showing residual mediastinal tumor and midline abdominal metastases...

We report two patients referred to 2 day stress-rest single photon emission computed tomography for diagnosis of ischemia who elicited a transient left bundle branch block during dipyridamole intravenous infusion. The conduction disturbance disappeared after aminophyline infusion and became permanent during follow-up. Possible mechanisms underlying this unusual phenomenon in the absence of myocardial ischemia are discussed.

Tracheal metastases from renal cell carcinoma (RCC) are extremely rare. Most common primary malignancy metastasizing to this unusual location usually comes from lung region while it is rare to have tracheal metastases from nonpulmonary malignancies such as breast, thyroid, colorectal carcinoma, and melanoma. The lesions detected on fluorine-18 fluorodeoxyglucose (F-18 FDG) positron emission tomography/computed tomography (PET/CT) scan, especially in the head and neck region, soft tissue, and muscular compartment during follow-up of RCC patients raise the possibility of metastatic lesions in these regions, though rarely encountered...

Sarcomas are a heterogeneous group of rare tumors and arise either from soft tissue or from bone. Soft-tissue sarcomas (STSs) initially metastasize to the lungs. Metastases to extrapulmonary sites such as liver, brain, and soft tissue distant from primary tumor usually develop later. However, cases with isolated adrenal metastasis without disseminated disease have been reported in literature. We present a case of primary myxoid liposarcoma of the lower limb, in which staging (18)-F fluorodeoxyglucose positron emission tomography-computed tomography (FDG PET-CT) scan detected a suspicious FDG avid adrenal lesion which eventually on resection was diagnosed as asymptomatic pheochromocytoma...

We evaluated the association between serum prostate specific antigen (PSA) level and kinetics to predict (18)F-sodium fluoride positron emission tomography-computed tomography ((18)F-NaF PET-CT) positivity for first bone metastases in men with biochemical recurrence after radical prostatectomy. All (18)F-NaF PET-CT scans that were performed at our institution during 2010-2014 were queried to find patients who demonstrated biochemical recurrence after radical prostatectomy. Records were reviewed to obtain data on PSA levels and kinetics at the time of (18)F-NaF PET-CT and pathologic features of the prostatectomy specimen, which were then used for receiver operating characteristic (ROC) analysis to determine predictability for (18)F-NaF PET positivity...

The present study aimed at exploring the patient and imaging characteristics of primary neuroendocrine tumors (NETs) of rare sites who presented with metastatic and/or advanced inoperable stages and therefore was considered for peptide receptor radionuclide therapy (PRRT) with (177)Lu-DOTATATE. A retrospective analysis was undertaken of these patients focusing on the aforementioned aspects. All patients underwent dual-tracer molecular functional imaging with somatostatin receptor (SSTR)-based imaging (with either (99m)Tc-HYNIC-TOC or (68)Ga-DOTATATE) and (18)fluorine fludeoxyglucose positron emission tomography-computed tomography as the pretherapy assessment...

Single isotope 99mTc single-photon emission computed tomography-myocardial perfusion imaging (SPECT-MPI) is the most commonly used protocol for nuclear stress testing. Transient ischemic dilation of the left ventricle (TID) has been considered a specific marker of severe coronary artery disease (CAD). Recent publications have questioned the clinical utility of TID, specifically with regadenoson as a stressor and 4DM-SPECT software for TID analysis. These findings have not been demonstrated using other imaging packages...

In this study, we compared the patients who underwent coronary angiography (CAG), followed by revascularization by coronary artery stent implantation according to the CAG results without any evidence of ischemia with myocardial perfusion scintigraphy (MPS), and the patients who underwent revascularization by coronary artery stent implantation following the detection of ischemia in MPS before CAG in terms of the mortality and hospitalization due to acute coronary syndrome (ACS). Between January 2009 and January 2016, a total of 407 patients (52% males, 48% females; mean age: 66 ± 9 years; range: 40-85 years) who underwent CAG following diagnosis of stable angina and underwent coronary artery stenting were retrospectively analyzed...

Early identification of diastolic dysfunction of patients with diabetes is important in preventing cardiac events. In this study, we aimed to show that both myocardial perfusion and diastolic function parameters can be evaluated in diabetic patients with possible silent cardiac symptoms using gated single-photon emission computed tomography (G-SPECT). We examined eighty patients: Forty with and forty without diabetes. The patients were compared in terms of systolic and diastolic parameters obtained using G-SPECT...

To evaluate the accuracy of fluorodeoxyglucose positron emission tomography/computed tomography (PET/CT) in staging and restaging of patients with mucosal melanomas (MM) of head and neck. Patients who underwent PET/CT at our institution, with a biopsy proven diagnosis of MM of the head and neck between March 2006 and December 2013 were included in the study. Nineteen patients with MM of the nasal cavity, paranasal sinuses, and oral cavity were included, of which 12 were for staging and seven for restaging. PET/CT had 100% sensitivity (SN), specificity (SP), positive predictive value (PPV), and negative predictive value (NPV) for detection of the primary...

Distant metastases change the prognosis of patients with nasopharyngeal carcinoma (NPC) which most commonly metastasizes to the bone. (18)F-fluorodeoxyglucose ((18)F-FDG) positron emission tomography/computed tomography (PET/CT) is reported as useful in imaging NPC metastases. Our study assesses the incidence and distribution of bone metastases detected by (18)F-FDG PET/CT in NPC. 717 (18)F-FDG PET/CT scan reports of histologically proven NPC patients imaged in Singapore General Hospital, Singapore, between 2003 and 2009 were reviewed for the total number of metastases (scanned from vertex to mid-thigh) and analyzed for distribution...

Lymph node staging plays an important role in planning initial management in nonmetastatic prostate cancer. This article compares the role of (68)Gallium ((68)Ga)-prostate specific membrane antigen (PSMA) positron emission tomography-computed tomography (PET-CT) with magnetic resonance imaging (MRI), which is considered the standard staging modality. Out of 39 high-risk prostate cancer patients who underwent (68)Ga-PSMA PET-CT for staging (December 2014-December 2015), 12 patients underwent radical prostatectomy along with ePLND and were included in the analysis...

Ovarian cancer (OC) often presents at an advanced stage with frequent relapses despite optimal treatment; thus, accurate staging and restaging are required for improving treatment outcomes and prognostication. Conventionally, staging of OC is performed using contrast-enhanced computed tomography (CT). Nevertheless, recent advances in the field of hybrid imaging have made positron emission tomography/CT (PET/CT) and PET/magnetic resonance imaging (PET/MRI) as emerging potential noninvasive imaging tools for improved management of OC...

Calciphylaxis, also known as calcific uremic arteriolopathy, is an uncommon disease, typically found in patients with the end-stage renal disease. Pathophysiological features include small vessel vasculopathy with mural calcification, fibrosis, and thrombosis. The clinical presentation varies but often consists of the necrosis of skin and subcutaneous tissues, with or without visceral organ involvement due to small vessel vasculopathy. This condition has a significant morbidity and mortality, making accurate diagnosis imperative...

We report a case of a 29-year-old female with the family history of medullary thyroid carcinoma (MTC) presenting with hematuria and tachycardia, who was found to have bilateral adrenal masses on abdominal computed tomography and biochemical testing compatible with pheochromocytoma. Iodine-123 (I-123) metaiodobenzylguanidine (MIBG) scintigraphy for preoperative planning prior to planned adrenalectomy revealed incidental synchronous unifocal MTC, along with expected bilateral adrenal pheochromocytomas. Pathology confirmed these findings, and subsequent genetic testing confirmed a rearranged during transfection proto-oncogene mutation on exon 11, confirming the clinical diagnosis of multiple endocrine neoplasia 2A (MEN 2A)...

We present a case of a 15-year-old male with primary bone lymphoma who was initially referred for suspicion of chronic osteomyelitis of the mandible. A bone scan and gallium scan demonstrated congruent uptake in the mandible, suggestive of chronic osteomyelitis. A biopsy subsequently showed B-cell lymphoma of the bone with low Ki-67. A fluorodeoxyglucose positron emission tomography (FDG-PET) scan performed before therapy for staging revealed no increased uptake in the mandible. This case shows an atypical presentation of a rare disorder and is presented to emphasize the importance of baseline FDG-PET...

Bone scintigraphy with (99m)Tc diphosphonates may exhibit extraosseous lesions in addition to metastatic lesions. Multiple factors can affect extraosseous (99m)Tc methylene diphosphonate (MDP) uptake. Similar uptake pattern of (99m)Tc MDP and fluorine-18 fluorodeoxyglucose ((18)F FDG) in hepatic metastasis was not already notified. In our case, initial tumor necrosis and subsequent intracellular calcification resulted in similar (99m)Tc MDP and (18)F FDG accumulation in the metastatic area.
