Abstract
Botryoid rhabdomyosarcoma is a rare and aggressive malignancy that primarily affects the female genital tract in children. It arises from embryonal rhabdomyoblasts. The vagina is the most common site, but it can also occur, although rarely, in the cervix or uterine fundus. We report the case of a 2-year-old girl who presented with a rapidly growing mass in the vulvar region. A pelvic MRI revealed a grape-like mass occupying the vaginal lumen, suggestive of botryoid rhabdomyosarcoma. Biopsy of the mass confirmed the diagnosis.

Abstract
Rhabdomyosarcomas are the most common soft-tissue sarcomas, found usually in the younger age group. Histologically, they are subdivided into embryonal, alveolar, pleomorphic and not otherwise specified. They have a heterogenous appearance on imaging with few additional characteristic features based on the subtype. Botryoid variant of embryonal rhabdomyosarcoma commonly involves the genitourinary and the biliary system. They can be multifocal. Most of these lesions have a heterogenous appearance on imaging with areas of necrosis and haemorrhage. On ultrasound, they are polypoidal with cystic areas and are vascular. The lesions are hyperintense on T2 sequences, isointense to the skeletal muscle on T1 sequences and show heterogenous enhancement. Surgery is the mainstay of treatment along with radiotherapy or chemotherapy depending on the site and the stage of the tumour. We report a case of botryoid variant of rhabdomyosarcoma involving the vagina and the urinary bladder.

Abstract
Introduction and importance Rhabdomyosarcoma is a malignant tumour that originates from immature muscle cells and belongs to the category of soft-tissue sarcomas. It is predominantly diagnosed in children under the age of 6. This condition can manifest within the genitourinary tract and may exhibit non-specific symptoms such as changes in bowel habits and fever. Early detection and a comprehensive, multidisciplinary approach are essential to achieving more favourable outcomes. This report highlights an uncommon case of urogenital rhabdomyosarcoma in a 15-year-old girl, in addition to the presence of a rectovaginal fistula. Case presentation A 15-year-old girl with presented with fever, altered bowel habits, and a lump in her lower abdomen, abdominal discomfort, and incomplete bowel evacuation. She also had faecal discharge from the vagina. Diagnostic imaging and biopsy confirmed urogenital rhabdomyosarcoma with a rectovaginal fistula. The patient is currently undergoing induction chemotherapy and is scheduled for radiation therapy and surgery. Clinical discussion Rhabdomyosarcoma is a rare paediatric oncologic concern due to its aggressive nature and potential metastasis. The presentation varies based on age, tumour location, and metastasis presence. This patient presented with altered bowel habits, a pelvic mass and unusual feculent discharge, suggesting a rectovaginal fistula. Diagnostic imaging confirmed the diagnosis, and induction chemotherapy led to a positive response and reduced tumour size. Conclusion Urogenital rhabdomyosarcoma is an aggressive malignancy with non-specific symptoms, making early diagnosis challenging. An accurate diagnosis requires high suspicion, imaging, and a biopsy. Multidisciplinary management, including surgery, chemotherapy, and radiation therapy, improves outcomes and improves paediatric patients' prognosis and quality of life.

Abstract
Infantile hemangioma (IH) is the most common neoplasm in children, but it may mimic other types of vascular anomalies or nonvascular benign and malignant tumors. In most cases, the clinical appearance, time of onset, and pattern of involution facilitate its diagnosis. Imaging evaluation is not always needed since the IH features at clinical presentation are usually characteristic, but when needed, US and frequently MRI are the imaging modalities of choice. Clinical photography or photographic documentation plays a central role in monitoring these lesions over their clinical course. Photographic documentation can also add confidence and alert the radiologist when interpreting imaging studies. Some vascular anomalies, especially vascular malformations, are a frequent source of confusion, as these may resemble IHs clinically and at imaging. The lack of uniform terminology also hinders an accurate diagnosis. To unify the terminology and minimize confusion, the International Society for the Study of Vascular Anomalies created a helpful classification in 1994. In addition, radiologists need to be aware of and become familiar with other neoplasms in children that may resemble IH to avoid misdiagnosis and unnecessary procedures. Fibrous and lipomatous tumors are examples of benign tumors that can mimic IHs clinically and at imaging, whereas rhabdomyosarcoma, infantile fibrosarcoma, neuroblastoma, and lymphoproliferative disorders are examples of malignant neoplasms. The authors review the features of IH at clinical presentation and imaging evaluation, highlighting its different phases of evolution and stressing the importance of photographic documentation. The authors also review pitfalls of IH with helpful pearls for differentiation. ©RSNA, 2023 Quiz questions for this article are available in the supplemental material.

Abstract
An isolated intravesical cavernous hemangioma of the bladder represents a rare occurrence, frequently posing challenges in distinguishing it from rhabdomyosarcoma. In this context, we present a case involving an 8-year-old male child diagnosed with a cavernous hemangioma of the bladder, which on MRI closely resembles the findings of rhabdomyosarcoma. Under such circumstances, the utilization of slow-flow images in contrast-enhanced MRI holds promise as a potentially valuable tool for discriminating between cavernous hemangioma and rhabdomyosarcoma in similar clinical scenarios.

Abstract
Background Rhabdomyosarcoma (RMS) is a malignant childhood tumor that most commonly involves the skeletal muscles of the head and neck, genitourinary tract, limbs, and, rarely, the spine. Case Description A 19-year-old male presented with cauda equina symptoms. Magnetic resonance imaging showed a C7/T1 homogeneously enhancing lesion, causing pathological fracture of the T1. Similar lesions were found on T3 and S1-S2 levels. CT-guided biopsy and immunohistochemistry confirmed the diagnosis of highly malignant alveolar RMS. He underwent multi-level laminectomies with partial tumor debulking but was paraplegic postoperatively. Conclusion Spinal RMS rarely involves the soft tissues of the spine and should be surgically resected if feasible. Nevertheless, the long-term prognosis is poor regarding tumor recurrence and metastases.

Abstract
The International Soft Tissue Sarcoma Database Consortium (INSTRuCT) consists of a collaboration between the Children's Oncology Group (COG) Soft Tissue Sarcoma Committee, the European pediatric Soft Tissue Sarcoma Study Group (EpSSG), and the Cooperative Weichteilsarkom Studiengruppe (CWS). As part of the larger initiative of INSTRuCT to provide consensus expert opinions for clinical treatment of pediatric soft tissue sarcoma, we sought to provide updated, evidenced-based consensus guidelines for local treatment of parameningeal rhabdomyosarcoma using both existing literature as well as recommendations from the relevant cooperative group clinical trials. Overall, parameningeal rhabdomyosarcoma represents a distinctly challenging disease to treat, given its location near many critical structures in the head and neck, frequently advanced local presentation, and predilection for local failure. Definitive chemoradiation remains the standard treatment approach for parameningeal rhabdomyosarcoma, with surgery often limited to biopsy or salvage therapy for recurrent disease. In this consensus paper, we specifically discuss consensus guidelines and evidence for definitive local management with radiotherapy, with a focus on imaging for radiotherapy planning, dose and timing of radiation, approach for nodal irradiation, various radiation techniques, including proton therapy, and the limited role of surgical resection.

Abstract
PURPOSE Childhood RMS is a rare malignant disease in which evaluation of tumour spread at diagnosis is essential for therapeutic management. F-18 FDG-PET imaging is currently used for initial RMS disease staging. MATERIALS AND METHODS This multicentre retrospective study in six French university hospitals was designed to analyse the prognostic accuracy of MTV at diagnosis for patients with RMS between 1 January 2007 and 31 October 2017, for overall (OS) and progression-free survival (PFS). MTV was defined as the sum of the primitive tumour and the largest metastasis, where relevant, with a 40% threshold of the primary tumour SUVmax. Additional aims were to define the prognostic value of SUVmax, SUVpeak, and bone lysis at diagnosis. RESULTS Participants were 101 patients with a median age of 7.4 years (IQR [4.0-12.5], 62 boys), with localized disease (35 cases), regional nodal spread (43 cases), or distant metastases (23). 44 patients had alveolar subtypes. In a univariate analysis, a MTV greater than 200 cm3 was associated with OS (HR = 3.47 [1.79;6.74], p<0.001) and PFS (HR = 3.03 [1.51;6.07], p = 0.002). SUVmax, SUVpeak, and bone lysis also influenced OS (respectively p = 0.005, p = 0.004 and p = 0.007) and PFS (p = 0.029, p = 0.019 and p = 0.015). In a multivariate analysis, a MTV greater than 200 cm3 was associated with OS (HR = 2.642 [1.272;5.486], p = 0.009) and PFS (HR = 2.707 [1.322;5.547], p = 0.006) after adjustment for confounding factors, including SUVmax, SUVpeak, and bone lysis. CONCLUSION A metabolic tumor volume greater than 200 cm3, SUVmax, SUVpeak, and bone lysis in the pre-treatment assessment were unfavourable for outcome.

Abstract
Local treatment plays a key role for patients' outcome in tumors of the urogenital tract in children. Despite a great variety of different etiologies, the specific localization of pediatric urogenital tumors renders several characteristic demands to the treating personnel. Surgery and radiotherapy are the main elements of local treatment in this group of neoplasms. Numerous new guidelines and innovative technical developments of surgery and radiotherapy have recently been integrated into treatment concepts for pediatric urogenital tumors. Due to the broadness of the field it is not possible to give a full overview over all aspects. Therefore, this article highlights the most important innovations and new guidelines of surgery and radiotherapy of pediatric urogenital tumors.

Abstract
BACKGROUND Rhabdomyosarcoma (RMS) is a rare malignant tumor of mesenchymal origin that mainly affects children. Spindle cell/sclerosing RMS (SSRMS) is even rarer. It is a new subtype that was added to the World Health Organization disease classification in 2013. To the best of our knowledge, this is the first reported case of adult SSRMS disease classification originating in the temporal muscle.
CASE SUMMARY SSRMS originating in the temporal muscle of a male adult enlarged rapidly, destroyed the skull, and invaded the meninges. The tumor was completely removed, and the postoperative pathological diagnosis was SSRMS. Postoperative recovery was good and chemotherapy and radiotherapy were given after the operation. Followed up for 3 mo, no tumor recurred.
CONCLUSION RMS is one of the differential diagnoses for head soft tissue tumors with short-term enlargement and skull infiltration. Preoperative computed tomography or magnetic resonance imaging is necessary for early detection of tumor invasion of the skull and brain tissue.

Abstract
Differentiation of malignant from benign soft tissue tumors is challenging with imaging alone, including that by magnetic resonance imaging and computed tomography. However, the accuracy of this differentiation has increased owing to the development of novel imaging technology. Detailed patient history and physical examination remain essential for differentiation between benign and malignant soft tissue tumors. Moreover, measurement only of tumor size based on Response Evaluation Criteria In Solid Tumors criteria is insufficient for the evaluation of response to chemotherapy or radiotherapy. Change in metabolic activity measured by 18F-fluorodeoxyglucose positron emission tomography or dynamic contrast enhanced-derived quantitative endpoints can more accurately evaluate treatment response compared to change in tumor size. Magnetic resonance imaging can accurately evaluate essential factors in surgical planning such as vascular or bone invasion and "tail sign". Thus, imaging plays a critical role in the diagnosis and treatment of soft tissue tumors.

European guideline for imaging in paediatric and adolescent rhabdomyosarcoma - joint statement by the European Paediatric Soft Tissue Sarcoma Study Group, the Cooperative Weichteilsarkom Studiengruppe and the Oncology Task Force of the European Society of Paediatric Radiology. Pediatr Radiol 2021; 51:1940-1951. [PMID: 34137936 PMCID: PMC8426307 DOI: 10.1007/s00247-021-05081-0] [Citation(s) in RCA: 24] [Impact Index Per Article: 8.0] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Download PDF] [Journal Information] [Submit a Manuscript] [Subscribe] [Scholar Register] [Received: 01/25/2021] [Revised: 01/25/2021] [Accepted: 04/14/2021] [Indexed: 02/08/2023]
Abstract
Appropriate imaging is essential in the treatment of children and adolescents with rhabdomyosarcoma. For adequate stratification and optimal individualised local treatment utilising surgery and radiotherapy, high-quality imaging is crucial. The paediatric radiologist, therefore, is an essential member of the multi-disciplinary team providing clinical care and research. This manuscript presents the European rhabdomyosarcoma imaging guideline, based on the recently developed guideline of the European Paediatric Soft Tissue Sarcoma Study Group (EpSSG) Imaging Committee. This guideline was developed in collaboration between the EpSSG Imaging Committee, the Cooperative Weichteilsarkom Studiengruppe (CWS) Imaging Group, and the Oncology Task Force of the European Society of Paediatric Radiology (ESPR). MRI is recommended, at diagnosis and follow-up, for the evaluation of the primary tumour and its relationship to surrounding tissues, including assessment of neurovascular structures and loco-regional lymphadenopathy. Chest CT along with [F-18]2-fluoro-2-deoxyglucose (FDG) positron emission tomography (PET)/CT or PET/MRI are recommended for the detection and evaluation of loco-regional and distant metastatic disease. Guidance on the estimation of treatment response, optimal long-term follow-up, technical imaging settings and standardised reporting are described. This European imaging guideline outlines the recommendations for imaging in children and adolescents with rhabdomyosarcoma, with the aim to harmonise imaging and to advance patient care.

Abstract
Ultrasonography (US) is usually the first imaging examination performed to evaluate palpable or visible superficial soft tissue lesions that are common in children. Although clinical assessments, such as age at presentation, clinical course, and overlying skin discoloration, are important for the differentiation of pediatric soft tissue lesions, US allows a specific diagnosis of some typical benign lesions and helps in guiding further investigation since it provides detailed information about the lesion location, characterization including solid versus cystic, vascularity, and compressibility. Therefore, sufficient knowledge of the normal anatomy, proper ultrasonographic techniques, and the imaging findings of common and uncommon soft tissue lesions in children are crucial for accurate assessment and management of patients. In this article, we review the techniques and imaging findings focusing on the ultrasonographic features of a variety of superficial soft tissue lesions detected in children.

Abstract
The differential diagnosis of a masticator space (MS) lesion is broad, owing in part to the multiple structures contained within such a small region. It is also because the MS is adjacent to many of the other deep spaces within the head and neck, which can act as gateways for disease spread. Therefore, emergency radiologists must be familiar with anatomy of the MS, as well as adjacent spaces in order to provide an accurate diagnosis to the referring clinician. This article illustrates the anatomy and common pathologies within the MS using a case-based multimodality approach. Common masticator space pathologies can be categorized into inflammatory/infectious, neoplastic, and vasoformative lesions. Important imaging features of MS lesions and patterns of disease spread will be discussed, with the aim of making this complex deep space more approachable in the emergent setting.

Abstract
We present a case of a perianal and perianal spindle cell variant of embryonal rhabdomyosarcoma (RMS). A 3-month-old male child presented with a firm mass in the perianal region. The mass measured 5 cm × 3 cm × 2 cm was surgically removed. Biopsy was performed; it showed embryonal RMS. Immunohistochemical (IHC) stains were performed using vimentin, myogenin, spinal muscular atrophy, and muscle-specific actin, which all showed positive results. The histological examination and IHC stains were consistent with a spindle cell variant of embryonal RMS.

Abstract
A wide range of congenital or acquired conditions, some pretty rare, may affect the vulva and vagina in children. Swelling, visible or palpable masses and abnormal discharges are common symptoms of conditions affecting the vulva and/or the lower genital tract. The majority of these diseases are benign. Ultrasonography is pivotal to elucidate the anatomical origin of these conditions and make the diagnosis. Magnetic resonance imaging can be relevant to improve diagnostic confidence and, if needed, to plan more accurate surgical treatment. The aim of this pictorial essay is to review the related imaging findings to help make radiologists familiar with these conditions.

Abstract
Introduction Orbital embryonal rhabdomyosarcoma is a rare childhood malignancy with a good prognosis, but the optimal treatment remains unclear. Using a population-based cancer registry, we assessed the prognoses and survival outcomes of patients with orbital embryonal rhabdomyosarcoma according to the local treatment strategy. Patients and methods Patients diagnosed with orbital embryonal rhabdomyosarcoma between 1988 and 2012 as part of the Surveillance Epidemiology and End Results program were included. Univariate and multivariate Cox regression analyses were performed to determine the prognostic factors associated with cause-specific survival (CSS) and overall survival (OS). Results In total, 102 patients were included; their median age was 6 years, 78.4% were white, and 56.9% were male. The median tumor size was 30 mm. Of 20 patients with an available histologic grade, the tumors of 90% were poorly differentiated/undifferentiated. Of 92 patients with available surgical and radiotherapy (RT) statuses, 50 (54.3%), 36 (39.1%), and 6 (6.5%) received surgery and RT, primary RT, and primary surgery, respectively. Ninety-five patients (93.1%) received chemotherapy. The 5- and 10-year CSSs of the entire cohort were 94.3% and 92.2%, respectively. The 5- and 10-year OSs were 93.3% and 91.3%, respectively. In 95 patients who were followed up for at least 12 months, there were no significant prognostic factors related to CSS and OS. Furthermore, the local treatment strategy did not significantly affect CSS (P=0.29) or OS (P=0.468). Conclusion There is no local treatment of choice for orbital embryonal rhabdomyosarcoma in terms of survival. However, RT is a reasonable alternative treatment to surgery.

Abstract
Rhabdomyosarcoma (RMS) is a malignant mesenchymal tumor arising from the embryonal muscle cells (rhabdomyoblasts), and is the most common soft tissue sarcoma in children and young adults accounting for 4-6% of all malignancies in this age group. Though rare overall, embryonal rhabdomyosarcoma is the most common malignancy arising in the pediatric female genitourinary tract with sarcoma botryoides being the most common variant of the tumor. In young and adolescent individuals, the cervix and uterus are affected; whereas in infants, vaginal lesions are more common. Imaging plays a crucial role not only in the initial diagnosis but also in long-term follow-up of genital RMS. We describe a rare case of embryonal rhabdomyosarcoma of the vagina occurring in a 23-year-old female who presented with abnormal vaginal bleeding ever since she was a child.

Abstract
Rhabdomyosarcoma (RMS) represents a malignant tumor of skeletal muscle cells arising from rhabdomyoblasts. RMS represents the most common soft tissue sarcoma in children. In adults it is uncommon and accounts for less than 1% of all malignant solid tumors. While treatment protocols are well known for children, there is no standardized regimen in adults. This is one reason, why the outcome in adults is worse than in children. We present the case of a 59-year-old female patient with pleomorphic rhabdomyosarcoma (PRMS) infiltrating the thoracic spine. Multimodality treatment was performed including en-bloc resection, adjuvant multidrug chemotherapy and radiation beam therapy. The patient was tumor free and had no relapse within 6 month follow-up.

Abstract
We herein reviewed 18F-fluoro-2-deoxyglucose (18F-FDG) positron emission tomography (PET)/computed tomography (CT) findings in a number of musculoskeletal lesions including malignant tumors, benign tumors, and tumor-like lesions with correlations to other radiographic imaging modalities, and described the diversity of the 18F-FDG PET/CT findings of this entity. Malignant primary musculoskeletal tumors are typically 18F-FDG avid, whereas low-grade malignant tumors show mild uptake. Benign musculoskeletal tumors generally show a faint uptake of 18F-FDG, and tumor-like conditions also display various uptake patterns of 18F-FDG. Although musculoskeletal tumors show various uptakes of 18F-FDG on PET/CT, its addition to morphological imaging modalities such as CT and MRI is useful for the characterization and differentiation of musculoskeletal lesions.

Abstract
Desmoplastic small round cell tumor is a rare, aggressive tumor primarily affecting young males. It is considered a childhood cancer, and is characterized by a unique chromosomal translocation which leads to failure to suppress tumor growth. It is classified as a soft tissue sarcoma, sharing some features with other small round cell tumors such as Ewing's Sarcoma and primitive neuroectodermal tumor. Typical imaging findings include multiple heterogeneous, lobular abdominal masses, which can grow very large. Often there is a dominant mass with additional peritoneal, omental, retroperitoneal and retrovesical masses. Prognosis is relatively poor with a 3 year survival rate of 50% in those treated aggressively with surgical resection, chemotherapy, and radiation therapy. The clinical presentation, imaging characteristics and pathology are discussed in regards to a recent case.

Abstract
Introduction Alveolar rhabdomyosarcomas of the mediastinum in children are rarely reported. Multimodality therapy including chemotherapy, surgery and radiotherapy make up the backbone of the treatment of childhood rhabdomyosarcomas. Complete resection whenever achievable is an important prognostic factor. However, complete resection of tumors in the mediastinum often poses a unique challenge to thoracic surgeons due to their close proximity to important neurovascular structures. Complete resection may not always be possible and judicious peri-operative planning and preparation are required to avoid creating unnecessary surgical morbidities resulting in delay of adjuvant therapy. Case presentation A 4-month-old Chinese baby boy was presented to our hospital with stridor, shortness of breath and episodes of cyanosis. Imaging studies found an anterior mediastinal mass compressing the trachea and other neurovascular structures and he was diagnosed to have alveolar rhabdomyosarcoma. Our patient received upfront chemotherapy and subsequently open resection of the mass was attempted via median sternotomy. Intraoperatively, the mass had invaded into the great vessels, precluding a complete resection. Debulking surgery was performed instead and our patient received timely postoperative chemoradiotherapy. Conclusions We report a rare case of childhood alveolar rhabdomyosarcoma of the mediastinum with vascular invasion treated with chemoradiotherapy and debulking surgery. Complete resection was not possible due to the close proximity to the great vessels. Different surgical approaches to the mediastinum have been reported in adults and children alike. Regardless of the surgical access, the treatment of childhood rhabdomyosarcomas should be individualized, with careful balance between surgical clearance and surgical morbidity.

Abstract
Rhabdomyosarcoma (RMS) is a highly malignant tumor and is one of the few life-threatening diseases that present first to the ophthalmologist. It is the most common soft-tissue sarcoma of the head and neck in childhood with 10% of all cases occurring in the orbit. RMS has been reported from birth to the seventh decade, with the majority of cases presenting in early childhood. Survival has changed drastically over the years, from 30% in the 1960's to 90% presently, with the advent of new diagnostic and therapeutic modalities. The purpose of this review is to provide a general overview of primary orbital RMS derived from a literature search of material published over the last 10 years, as well as to present two representative cases of patients that have been managed at our institute.

Abstract
PURPOSE To analyze the radiological and clinicopathological features of peripheral primitive neuroectodermal tumor (pPNET). MATERIALS AND METHODS We retrospectively reviewed the computed tomography (CT) and magnetic resonance (MR) imaging of 14 cases of pPNET confirmed immunohistochemically. Relevant clinical data was also obtained. RESULTS Of 14 cases, there were 10 male and 4 female with a mean age of 28 years. The main symptoms were the aggravated pain of the lesion site and enlarged palpable masses. Fourteen lesions were located in the chest wall (n = 4), retroperitoneum (n = 3), pelvic cavity (n = 2), intraspinal area (n = 2), nasal cavity (n = 1), leg ( n= 1) and iliac bone (n = 1). Eleven lesions originating from the soft tissue mainly demonstrated large and infiltrative mass with (n = 4) or without (n = 7) bony invasion. Ten cases of them showed heterogeneous density with patchy, necrotic foci and moderate heterogeneous enhancement. Four of them with large cystic area contained irregular septations within them. Two intraspinal cases had extradural lesions, extending through the intervertebral foramen and formed paraspinal soft tissue masses with vertebral destruction. The case within iliac bone demonstrated extensive mixed (lytic/osteoblastic) lesion with large adjacent soft tissue mass. After surgery or therapy, 10 patients died of local recurrences or metastases. CONCLUSION The diagnosis of pPNET should be suggested in young patient when imaging depicts a large, ill-defined, soft-tissue mass containing area of cystic degeneration with internal septations and extending along the neural route and nearby the middle of the trunk. The key for correct diagnosis is to inosculate imaging to clinical data.

Abstract
After initial evaluation with radiography, magnetic resonance (MR) imaging is the most common modality used to establish the diagnosis and characterize osseous and soft tissue tumors of the hip. Tumors involving the proximal femur are often benign, and MR imaging can be specific in diagnosing solitary bone cyst, osteochondroma, and chondroblastoma. Benign and malignant soft tissue tumors about the hip are often nonspecific in their MR imaging appearances, but knowledge of the patient's age may direct a more limited differential diagnosis. In the setting of malignancy, MR imaging is commonly used to stage tumors and follow patients postoperatively.

Abstract
BACKGROUND Primary intraspinal sarcomas are very rare in children. Rhabdomyosarcoma (RMS) is a highly aggressive and rapidly growing sarcoma with skeletal origin that occasionally appears in the spinal epidural space. METHOD We report a 13-year-old girl who presented with back pain, progressive paraparesis, and urinary retention. She had muscular weakness in her lower extremities and absent deep tendon reflex. An epidural dumbbell-shape mass at T11-T12 level was observed on MRI. The patient underwent T12 hemilaminectomy, partial T11 hemilaminectomy, and right facetectomy. A large, firm, dark-red vascular epidural tumor was found compressing the cord. The tumor which extended to intracanal and foraminal parts was removed completely. DISCUSSION Histopathological examination revealed undifferentiated small round and oval tumoral cells. Immunohistochemical staining was positive for vimentin, desmin, and myogenin. The final diagnosis was alveolar RMS. She received radiotherapy and chemotherapy by vincristine, actinomycin-D, doxorubicin, and ifosfamide. The patient was in good condition with no tumor recurrence or metastasis at the 1-year follow-up.

Abstract
Sarcomas originating from abdominal organs are extremely rare, and literature in which investigators focus on their imaging features is scarce. This article aims to review the computed tomography and magnetic resonance imaging features of these rare tumors and to help in clinical diagnosis. Various sarcomas (eg, angiosarcoma, undifferentiated embryonal sarcoma, leiomyosarcoma, carcinosarcoma, rhabdomyosarcoma) originating, respectively, from different abdominal visceral organs (liver, pancreas, spleen, kidney, adrenal gland, uterus, and prostate gland) are reviewed along with cases we encountered.

Abstract
After a brief discussion of the rarity of soft tissue sarcomas in children and of the limited ability of magnetic resonance imaging to provide a tissue diagnosis, this article discusses the incidence, presentation, treatment, prognosis, and imaging characteristics of the more common and unusual pediatric soft tissue sarcomas. It begins with extensive discussion of rhabdomyosarcoma, synovial sarcoma, and congenital/infantile fibrosarcoma. It then presents a more abbreviated discussion of uncommon tumors such as alveolar soft part sarcoma, epithelioid sarcoma, extraosseous Ewing's sarcoma, granulocytic sarcoma, hemangiopericytoma, liposarcoma, malignant fibrous histiocytoma, malignant peripheral nerve sheath tumor, and undifferentiated sarcoma.

Abstract
A 16-day-old female was referred with congenital swelling on her right shoulder. On examination, there was a hard, round, ecchymotic, nontender, slightly movable, warm and shiny 10x15 cm mass on the right axillary pits which was extended to the right side of neck and chest wall. The mass separated the shoulder from the chest wall causing paralysis of right hand. Chest X-ray, ultrasound and MRI with contrast demonstrated a soft tissue mass suspected to be a hemangioma. The mass rapidly increased in size despite aggressive steroid therapy with rupture and bleeding. On the 45th post natal day the baby was taken to operating room to control the bleeding and if possible total excision of the mass. The mass was separated easily from the surrounding tissue and was excised along with right upper extremity. At the end of surgery the baby had cardiac arrest, and apparently died of Disseminated Intravascular Coagulation (DIC). The final pathology report was Rhabdomyosarcoma (RMS).

Abstract
OBJECTIVE The purpose of the study is to determine whether there are cross-sectional imaging features of pediatric rhabdomyosarcoma that are specific to the different pathologic subtypes of the tumor. MATERIALS AND METHODS Medical records of 14 pediatric patients who were diagnosed with rhabdomyosarcoma were reviewed retrospectively. Patient demographics, including age and sex, as well as final pathologic report were obtained. The initial CT, MRI, or both obtained at presentation, prior to the diagnosis being established, were reviewed by two radiologists. We recorded tumor features including site, size, margins, local extension, and presence of metastases. Presence of calcification, hemorrhage, or necrosis as well as attenuation and heterogeneity of the tumor were also recorded. RESULTS Ten of our fourteen patients were formally diagnosed with the embryonal subtype of rhabdomyosarcoma, while three were found to have the alveolar subtype, and one subtype was poorly differentiated. There was no significant difference in the attenuation and in the heterogeneity of the tumor between the embryonal and the alveolar subtype on CT. CONCLUSION Imaging features at presentation, such as attenuation and heterogeneity, could not correlate to the pathologic subtype of pediatric rhabdomyosarcoma.

Abstract
Congenital rhabdomyosarcoma of the tongue is exceedingly rare. Fibromatosis of the tongue is also rare, and very difficult to distinguish from the spindle cell variant of rhabdomyosarcoma. Both appear histologically as spindle neoplasms replacing normal striated musculature of the tongue. The treatment protocol for the former has been developed by the Intergroup Rhabdomyosarcoma Studies (IRS) I-IV and requires surgery, radiation, and chemotherapy. For fibromatosis, complete surgical excision is usually adequate without additional therapy, although some cases of aggressive fibromatosis also require chemotherapy. With significant differences in appropriate treatment and prognosis, each entity must not be mistaken for the other. We review the differences in radiologic, histologic, and immunohistochemical (IHC) features of both entities.

Abstract
Vascular tumours and malformations, fibrous and fibrohistiocytic tumours and pseudotumours are the most common benign soft-tissue masses observed in children, and can be treated conservatively. Rhabdomyosarcomas are the most frequent malignant tumours, accounting for about half of soft tissue sarcomas. A child referred for a soft-tissue mass should ideally be managed by a multidisciplinary team and primary excision should be proscribed until a definite diagnosis has been established. Clinical examination, conventional radiography and US with Doppler represent the first-line examinations and are sometimes sufficient to make a diagnosis. In all other situations, MRI is mandatory to establish the aggressiveness and extension of the tumour. This technique provides the relevant data to guide the decision regarding tissue sampling.

Abstract
A case of pleomorphic rhabdomyosarcoma of the larynx is presented, which is extremely rare in a laryngeal site. The symptomatology and macroscopic aspect of the neoplasm can simulate the presence of other neoplastic variants of the larynx, and, for this reason, histological examination must be associated with immunohistochemistry for correct diagnosis and treatment.

Abstract
Rhabdomyosarcoma (RMS) is the commonest paediatric soft-tissue sarcoma constituting 3-5% of all malignancies in childhood. RMS has a predilection for the head and neck area and tumours in this location account for 40% of all childhood RMS cases. In this review we address the clinical and imaging presentations of craniofacial RMS, discuss the most appropriate imaging techniques, present characteristic imaging features and offer an overview of differential diagnostic considerations. Post-treatment changes will be briefly addressed.

Abstract
Rhabdomyosarcoma is the most common soft tissue malignancy of childhood, but may occur extremely rarely in the neonatal period. There are only a few reports of rhabdomyosarcoma in neonates. Although, it may arise anywhere in the body, the head and neck, and genitourinary regions are the most frequent sites. Truncal and chest wall rhabdomyosarcoma is relatively rare occurrence. We report a neonate with embryonal rhabdomyosarcoma arising from the posterior chest wall muscles at birth. Computer Tomography scan raised the possibility of rhabdomyosarcoma or neurofibroma, fine-needle aspiration cytology was inconclusive. Total excision was done and chemotherapy given. At 6 months child is without recurrence.
