BACKGROUND: False-positive radioiodine (RAI) uptake related to chronic sinusitis and mucocele has only rarely been reported in patients with differentiated thyroid cancer (DTC) even with the recent use of single photon emission tomography with computed tomography (SPECT/CT) acquisition. No other etiology of sinus RAI uptake has been mentioned to date. OBJECTIVES: We report five cases of DTC patients with sinus RAI uptake on post-RAI scintigraphy. SPECT/CT clearly localized RAI uptake either in the sphenoid, the maxillary or the frontal sinus and highly suspected mucosal thickening in four patients and sinus aspergilloma in one patient...

A 38-week pregnant patient with history of cesarean delivery was admitted to the hospital for induction of labor after diagnosis of fetal demise. When the clinical picture became concerning for uterine scar dehiscence, an ultrasound was ordered. After targeted ultrasound of the lower uterine segment, the sonographer initially reported thin but intact lower uterine segment and normal positioning of the fetus. By keeping a high level of suspicion, the radiologist analyzed the images submitted and found other clues suggesting possible dehiscence or rupture...

Breast magnetic resonance (MR) imaging is the only breast imaging modality that consistently encompasses extramammary structures in the thorax and upper abdomen. Incidental extramammary findings on breast MR images of patients with a history of breast cancer or other malignancies are significantly more likely to be malignant and may affect staging and treatment. An understanding of the frequency, distribution, and context of extramammary findings on breast MR images and a familiarity with common and uncommon sites of breast cancer metastasis inform the differential diagnosis and prompt the appropriate diagnostic next step, to differentiate benign from malignant findings...

Many benign and reactive lesions of the breast show morphological overlap with malignant lesions. These benign mimics of malignancy often present diagnostic challenges to even the most experienced pathologists. This review focuses on several benign lesions of the breast that mimic malignant entities. For each of these lesions, we describe the key morphological and immunohistochemical features, potential diagnostic pitfalls, and our approach to arriving at the correct diagnosis.

The evaluation and management of athletes presenting with clinical features of migraine headache with aura in the setting of sports-related head trauma is challenging. We present a case report of a 15-yr-old boy with a history of migraine with visual aura that developed acute visual disturbance and headache after a head injury during an ice hockey game. The patient underwent comprehensive assessment at a multidisciplinary concussion program, including neuro-ophthalmological examination, neurocognitive testing, and graded aerobic treadmill testing...

We report the first series of five cases of prenatal diagnosis of pericallosal curvilinear lipoma (CL) and underline limitations and pitfalls in identifying a specific prenatal imaging pattern using ultrasound and MRI. On ultrasound, the main referring feature was a short corpus callosum in all cases. This subtle callosal dysgenesis was associated with a band of hyperechogenicity surrounding the corpus callosum, which can mimic the pericallosal sulcus, and increased in size over the third trimester in three out of four cases in which sonographic follow-up was obtained...

As the human papillomavirus (HPV)-related oropharyngeal squamous cell carcinoma epidemic has developed in the past several decades, it has become clear that these tumors have a wide variety of morphologic tumor types and features. For the practicing pathologist, it is critical to have a working knowledge about these in order to make the correct diagnosis, not to confuse them with other lesions, and to counsel clinicians and patients on their significance (or lack of significance) for treatment and outcomes...

Although retroperitoneal sarcomas are rare tumours, they can be encountered by a wide variety of clinicians as they can be incidental findings on imaging or present with non specific symptoms and signs. Surgical resection can offer hope of cure and patient outcomes are improved when patients are managed in high-volume specialist centers. Failure to recognize retroperitoneal sarcomas on imaging can lead to inappropriate management in inexperienced centers. Therefore it is critical that a diagnosis of retroperitoneal sarcoma should be considered in the differential diagnosis of a retroperitoneal mass with prompt referral to a soft tissue sarcoma unit...

INTRODUCTION: Computed Tomography (CT) plays an important diagnostic role in patients with sinonasal diseases and determines the treatment. The CT images clearly show fine structural architecture of bony anatomy thereby determining various anatomical variation, extent of disease and characterization of various inflammatory, benign and malignant sinonasal diseases. AIM: To evaluate sensitivity and specificity of CT in diagnosis of sinonasal diseases and to characterise the benign and malignant lesions with the help of various CT parameters...

De Garengeot's hernia is an eponym for femoral hernia containing vermiform appendix as its content and is named after Rene-Jacques croissant De Garengeot after he first described the condition in 1731. We present a case of a 38-year-old woman who presented with right inguinal swelling for 15 years associated with pain and vomiting for 2 days. Clinical examination revealed an irreducible femoral hernia. Emergency surgery was done and inflamed appendix was found as content of the sac. Appendectomy followed by mesh repair was done...

Vascular proliferations of the breast comprise a spectrum of benign and malignant lesions. In limited samples, such as core needle biopsies (CNB), these lesions may be difficult to distinguish due to significant overlap in morphological features. As the treatment and prognosis of these entities vary widely, it is important for pathologists to consider a complete differential diagnosis and correctly synthesise histological features, results of adjunctive immunohistochemical studies, and pertinent clinical and imaging information, to render an accurate diagnosis in such limited samples...

PURPOSE: Measured Hounsfield numbers in CT are used by radiologists to determine the presence of calcium or fat in lung nodules, either of which suggests a benign diagnosis. However, substantial variations in Hounsfield number may arise due to the use of different reconstruction parameters such as the filter/kernel, leading to measurement inaccuracies. This quality improvement project was developed to demonstrate measurement pitfalls and to identify acceptable conditions for incorporating Hounsfield values as a factor in lung nodule diagnosis...

Breast Ultrasound (US) is an important tool for both screening and diagnostic examinations. Although breast US has benefitted from significant recent technical improvements, its use for the retroareolar region is known to be more challenging than for other locations. The retroareolar location was defined by Giess et al. in 1998 as the region where any lesion is situated at less than two cm from the nipple and/or involves the nipple-areolar complex on mammogram. Understanding of the complex anatomy and physiology of the nipple-areolar region is important to avoid misinterpretation and misdiagnosis...

Comorbidities related to the cardiovascular system are one of the most prevalent in patients with acromegaly, and contribute to an increased risk of morbidity and all-cause mortality. Specifically, hypertension, cardiomyopathy, heart valve disease, arrhythmias, atherosclerosis, coronary artery disease, and cardiac dysfunction may be frequent findings. Although the underlying physiopathology for each comorbidity may not be fully elucidated, uncontrolled growth hormone/insulin-like growth factor 1 excess, age, prolonged disease duration, and coexistence of other cardio-vascular risk factors are significant influencing variables...

BACKGROUND: Differentiated squamous intraepithelial lesion (dSIL) is morphologically and immunohistochemically analogous in the whole anogenital region. dSIL is a premalignant lesion frequently misinterpreted histopathologically as a benign dermatosis. The authors describe a peculiar change in the basal cell layer of the epidermis/epithelium overlying anogenital melanocytic nevi that may histopathologically imitate dSIL. The aim of this study is to familiarize the pathologists with this pitfall to avoid its possible overdiagnosis as dysplasia...

AIMS: To characterize the clinicopathologic and genetic features of pleomorphic mantle cell lymphoma (PMCL) which morphologically mimics diffuse large B-cell lymphoma (DLBCL). METHODS AND RESULTS: We systematically screened 500 B-cell lymphomas morphologically compatible with DLBCL using an immunohistochemical algorithm of three markers (CD5, cyclin D1 and SOX11). Ten cases of PMCL were identified for further study, and surprisingly four (40%) of them were cyclin D1-negative...

Solid pseudopapillary tumor (SPT) is a rare pancreatic neoplasm with a reported incidence of 0.1% to 2.7% of all pancreatic tumors. Because radiological presentation of pancreatic tumors is quite overlapping, distinctive features in fine needle aspiration cytology (FNAC) helps in its diagnosis preoperatively. Being a low-grade malignancy presenting predominantly in young females, correct preoperative diagnosis minimizes the need of extensive surgery. SPT carries good prognosis without any adjuvant chemotherapy/radiotherapy in most cases, even in the presence of metastatic disease...

BACKGROUND: The role of fine-needle aspiration cytology (FNAC) in thyroid nodules has been well-studied but there is a paucity of studies solely involving papillary thyroid carcinoma (PTC). The diagnostic criteria for PTC are established but still there is a worrisome possibility of false positive and false-negative results, which can have a serious impact on patient care. This article correlates the cytological and histological diagnosis of PTC with an eventual aim of analyzing the cause of false positive and false negative results in order to prevent misdiagnosis...
