Abstract
BACKGROUND We present a case of metachronous cardiac and intramuscular metastases in a patient with a known history of radical nephroureterectomy for upper-tract urothelial carcinoma (UTUC). CASE REPORT A 58-year-old man had a history of metachronous renal pelvis urothelial carcinoma with prior left radical nephroureterectomy. He was also diagnosed with malignancy-associated deep vein thrombosis (DVT) and was on rivaroxaban. He presented at an oncology follow-up consult with shortness of breath and right scapular lump. CT scan revealed a soft-tissue mass at the surgical bed suspicious for local recurrence, as well as intracardiac hypodensities and intramuscular nodules in the right latissimus dorsi and right adductor muscles. The intracardiac hypodensities were located in the left atrial appendage and inter-atrial septum. Given that the patient had a history of DVT and in a pro-thrombotic state, differentials for the intracardiac densities included intracardiac thrombi or metastases. The intramuscular hypodensities were rim-enhancing. Given that the patient was on rivaroxaban, differentials included hematomas or metastases. As there was no overlying bruising and the lesions remained unchanged in size clinically, they were treated as metastases. The patient was treated with clexane but re-presented with worsening of shortness of breath and palpitations. CT scan showed increased size of intracardiac lesions, suggesting no response to anticoagulation, and therefore were likely metastatic in nature. He completed a 2-year course of IV pembrolizumab and was in complete remission. CONCLUSIONS Our case highlights the importance of this clinically challenging scenario when patients with known malignancy and on anticoagulation present with cardiac or musculoskeletal symptoms. Though these patients are at risk of thrombus and haematoma, cardiac and intramuscular metastasis should be considered, as the prognosis is guarded.

Abstract
Sinonasal organized hematoma is a rare condition characterized by an organizing blood clot in the sinonasal cavity, which consists of blood products, fibrin, and dilated blood vessels. As a benign entity with an aggressive imaging appearance, it is important to differentiate sinonasal organized hematoma from malignancies affecting the paranasal sinuses and nasal cavities to guide appropriate management. In this report, we discuss the clinical presentation and diagnostic evaluation of an 82-year-old male with a left maxillary sinus organized hematoma and provide a comprehensive review of the relevant literature.

Abstract
INTRODUCTION AND IMPORTANCE We present a relatively rare case of intrathoracic chronic expanding hematoma (CEH) after thoracic surgery for lung cancer. CEH is often difficult to distinguish from malignant tumors because of its large size and slow progressive enlargement. In this report, we describe the radiological features of CEH in detail. CASE PRESENTATION A 67-year-old man who underwent a left upper lobectomy for lung cancer at 46 years of age presented with hemosputum. Computed tomography revealed a large mass with central low attenuation. Calcification was detected in peripheral lesions of the mass. T2-weighted magnetic resonance imaging (MRI) revealed a mass with mixed low and high signal intensities. Based on the clinical course, the patient was diagnosed with an intrathoracic CEH. A left posterolateral thoracotomy was performed with the patient in the lateral position, and a mass encased in a tough capsule was resected. The postoperative histopathological findings were consistent with CEH. CLINICAL DISCUSSION CT of intrathoracic CEH shows a lesion with heterogeneous content, a thick wall, and calcifications. However, differentiation from malignant tumors is difficult using CT alone. MRI is a good diagnostic modality for CEH and often shows a mixture of low- and high-intensity areas on T2-weighted images. In addition, the patient's medical history is important because most cases of CEH have a history of trauma or surgery. CONCLUSION To diagnose intrathoracic CEH, it is essential to consider the patient's clinical course and MRI findings.

Abstract
The concept of personalized medicine refers to the tailoring of medical treatment to each patient's unique characteristics. Scientific advancements have led to a better understanding of how a person's unique molecular and genetic profile makes them susceptible to certain diseases. It provides individualized medical treatments that will be safe and effective for each patient. Molecular imaging modalities play an essential role in this aspect. They are used widely in screening, detection and diagnosis, treatment, assessing disease heterogeneity and progression planning, molecular characteristics, and long-term follow-up. In contrast to conventional imaging approaches, molecular imaging techniques approach images as the knowledge that can be processed, allowing for the collection of relevant knowledge in addition to the evaluation of enormous patient groups. This review presents the fundamental role of molecular imaging modalities in personalized medicine.

Abstract
ABSTRACT A 49-year-old Japanese man had a chief complaint of left hypochondrium pain, and a CT scan revealed a mass in the left retroperitoneal space. CT and MRI scans revealed a hemorrhagic component and surrounding fibrous tissues. FDG PET/CT images showed increased uptake in the peripheral rim of the mass, indicating a malignant tumor. The SUV max was 7.6. We surgically resected the mass. The pathological examination confirmed the diagnosis of chronic expanding hematoma. It is difficult to differentiate CEH from malignant tumors on imaging; this should be recognized as a diagnostic pitfall.

Int J Surg Case Rep 2020; 76:270-273. [PMID: 33053488 PMCID: PMC7566197 DOI: 10.1016/j.ijscr.2020.09.199] [Citation(s) in RCA: 1] [Impact Index Per Article: 0.3] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Download PDF] [Figures] [Journal Information] [Subscribe] [Scholar Register] [Received: 08/28/2020] [Revised: 09/29/2020] [Accepted: 09/29/2020] [Indexed: 12/01/2022] Open
Abstract
A chronic expanding hematoma of the adrenal gland is extremely rare. Chronic expanding hematomas mimic sarcomatous lesions. Gallium scintigraphy may help the differential diagnosis between chronic expanding hematomas and sarcomatous lesions. Complete resection of chronic expanding hematomas is the gold standard. Preoperative arterial embolization may reduce intraoperative bleeding on complete tumor removal.
Introduction A chronic expanding hematoma in the retroperitoneal space is a rare disease with poorly understood pathology, and preoperative diagnosis of such hematomas using conventional methods is sometimes difficult. Presentation of case A 68-year-old man with a history of slowly progressive abdominal distention was referred to our department for further evaluation. Contrast-enhanced CT revealed a large retroperitoneal tumor of the adrenal gland. MRI revealed that the tumor was iso-intense to hyperintense on T2-weighted imaging, with heterogeneous signal intensity on T1-weighted imaging without fat components. Angiography of the left adrenal artery confirmed many extravasations into the tumor. However, gallium scintigraphy showed no accumulation in the tumor. These findings were suggestive of a chronic expanding hematoma of left adrenal gland. This patient underwent complete tumor resection. Postoperative histopathological findings revealed a chronic expanding hematoma. Discussion Chronic expanding hematomas are slowly expanding, space-occupying masses as a result of trauma, surgery, or bleeding disorders. Chronic expanding hematomas mimic malignant tumors such as sarcomatous lesions. Although CT and MRI are used to obtain the diagnosis, the diagnosis is sometimes difficult. Gallium scintigraphs play a pivotal role in the differential diagnosis between them. Conclusion Gallium scintigraphs, magnetic resonance imaging and computed tomography, are useful tools to differentiate chronic expanding hematomas from sarcomatous lesions.

Abstract
CLINICAL INTRODUCTION: A 71-year-old man, with a history of chronic aortic regurgitation and negative follow-up after bladder cancer resection 10 months before, had an aortic valve surgery. Two months after, a mass near the right side of the heart had been detected by transthoracic echocardiography performed for dyspnoea, without a cough or fever. The quality of ultrasound images did not allow for an appropriate evaluation due to the outcomes of the sternotomy and the presence of calcified pachypleurite. In order to evaluate this finding, coronary CT (CCT) (figure 1A,B) and positron-emission tomography with 2-[18F] fluoro-2-deoxy-D-glucose (FDG-PET) (figure 1C) were performed. Finally, a cardiac magnetic resonance (CMR) was requested (figure 1D-F, see online supplementary videos).heartjnl;104/23/1936/F1F1F1Figure 1(A) Short axis image of early contrast enhancement phase coronary CT (CCT); (B) short axis of delayed phase of the same CCT; (C) lesion on positron-emission tomography with 2-[18F] fluoro-2-deoxy-D-glucose image (white arrow); CMR short axis (D) T2-weighted image with fat saturation; (E) T1-weighted image with fat-saturation; (F) T1-weighted image without fat-saturation.

Abstract
A 45-year-old woman who had undergone surgical repair for an atrial septal defect at the age of 7 years presented with multiple anterior mediastinal masses. Positron-emission tomography (PET) with 2-[18F]fluoro-2-deoxy-d-glucose (FDG) revealed high uptake in the masses. The findings were interpreted as mediastinal malignant tumors with dissemination. Biopsy was performed, and the histological diagnosis was phosphoglyceride crystal deposition disease without neoplastic changes. Although phosphoglyceride crystal deposition disease is rare, it should be recognized as a potential interpretive pitfall that mimics a malignant tumor in FDG-PET findings in a patient after cardiac surgery.

Abstract
Solid or nodular enhancement is typical of soft tissue sarcomas although high grade soft tissue sarcomas and those with internal hemorrhage often appear heterogeneous with areas of nonenhancement and solid or nodular enhancement. These MRI findings often prompt an orthopedic oncology referral, a biopsy or surgery. However, not all masses with these imaging findings are malignant. We report the multimodality imaging findings of two surgically proven chronic expanding hematomas (CEH) with imaging features that mimicked sarcomas. A third case of nonenhancing CEH of the lower extremity is also presented as a comparison. It is important that in the correct clinical scenario with typical imaging findings, the differential diagnosis of a chronic expanding hematoma be included in the workup of these patients. An image-guided biopsy of nodular tissue within such masses that proves to be negative for malignancy should not necessarily be considered discordant. A correct diagnosis may prevent a morbid unnecessary surgery and may indicate the need for a conservative noninvasive follow-up with imaging.

Abstract
Organizing hematoma of the paranasal sinuses is a diagnostic dilemma clinically and radiographically, mimicking benign or malignant neoplastic processes. Although the diagnostic rate of this disease has increased as characteristic imaging findings are somewhat elucidated, endoscopic examination, preoperative biopsy, and computed tomography (CT) imaging do not give helpful information in differentiating these lesions from malignant neoplastic processes. A 55-year-old man presented with a 4-month history of recurrent nasal bleeding. He also complained of a left-sided nasal obstruction. CT findings were highly suggestive of a malignant tumor of the maxillary sinus. However, based on fluorodeoxyglucose F18 positron-emission tomography (PET/CT) and magnetic resonance imaging (MRI), the provisional diagnosis of benign tumor rather than malignancy was made. Complete resection of the mass was achieved by simple transnasal endoscopic surgery using the Caldwell-Luc approach. Organizing hematoma of the maxillary sinus was diagnosed by histopathologic evaluation. The clinical, radiological, and histopathologic findings of the patient are presented. In this report, we have presented 18FDG-PET findings of organized hematoma of the maxillary sinus (OHMS) that showed an increased FDG uptake in the peripheral rim of the mass with central photopenia. To our knowledge, this is the first case report in the literature reporting FDG-PET/CT findings of OHMS. Careful interpretation of metabolic (FDG-PET/CT) and anatomic (CT and MRI) images should be performed to accurately characterize the expansile lesion of the maxillary sinus in order to increase specificity and reduce equivocal findings significantly.

Abstract
Introduction Chronic expanding hematoma is a rare persistent hematoma that can sometimes be misdiagnosed as a malignant tumor due to its clinical and radiological features. Case presentation A 42-year-old Japanese man with a large mass in his leg, suggestive of malignancy, presented to our hospital. He had been aware of the leg swelling for the last eight years. A magnetic resonance imaging scan demonstrated a large mass with two components. One was a large, well-defined cystic mass (13×9cm) showing high intensity on T1- and T2-weighted images, and the other was a solid mass (3.5×2.5cm, adjacent to the large mass) with high intensity on T1-weighted images. Two-[18F]fluoro-2 deoxy-D glucose positron emission tomography images revealed increased uptake with a maximum standardized uptake value of 15.8 in the solid mass. As these findings were considered suggestive of hematoma associated with a malignant lesion, an open biopsy was performed. A pathological examination demonstrated a hematoma with xanthogranuloma, and no malignant cells were evident. Therefore, we resected the tumor including both components, and the histological diagnosis was chronic expanding hematoma. Clinical diagnosis based on 2-[18F]fluoro-2 deoxy-D glucose uptake is sometimes limited by the fact that 2-[18F]fluoro-2 deoxy-D glucose is taken up by not only malignant tumor cells but also macrophages and tissues with granulation or inflammation. Conclusions Significantly increased standardized uptake value in the peripheral rim of the lesion on 2-[18F]fluoro-2 deoxy-D glucose positron emission tomography imaging, mimicking a soft tissue sarcoma, should be recognized as a potential diagnostic pitfall in cases of chronic expanding hematoma.
