Gastrointestinal stromal tumors (GIST) are the most common mesenchymal lesions of the gastrointestinal tract. Many are treated surgically with or without the use of adjuvant tyrosine kinase inhibitors. Metastases to lymph nodes are infrequent. In this article, we present a case of a perigastric nodule presenting 3 years postsurgical treatment for biopsy-proven GIST, clinically suspicious for a recurrent/metastatic GIST. The patient had also received adjuvant tyrosine kinase inhibitor therapy. Microscopic sections from the perigastric lesion showed a spindle cell nodule felt initially to represent a GIST with posttherapeutic changes...

BACKGROUND: Xanthogranulomatous inflammation is recognized as a subtype of cholecystitis; however, it can also occur in other organs. Xanthogranulomatosis of the kidney, bone, ovary, endometrium, vagina, prostate, lymph nodes and pancreas was reported. Herein, we report a case of laparoscopic splenectomy in a patient with xanthogranulomatosis of the spleen that was difficult to diagnose preoperatively. CASE PRESENTATION: A 63-year-old man with a past medical history of hyperlipidemia had gradually growing multiple splenic masses, which were revealed on abdominal ultrasonography...

Myositis ossificans is defined as a self-limiting pseudotumor composed of reactive hypercellular fibrous tissue and bone. USP6 rearrangements have been identified as a consistent genetic driving event in aneurysmal bone cyst and nodular fasciitis. It is therefore an integral part of the diagnostic workup when dealing with (myo)fibroblastic lesions of soft tissue and bone. Two cases of myositis ossificans with USP6 rearrangement were published so far. We determine herein the incidence of USP6 rearrangement in myositis ossificans using USP6 fluorescence in situ hybridization analysis (FISH)...

BACKGROUND: Recent evidence suggests that olfaction is impaired in patients with pseudotumor cerebri (PTC). OBJECTIVES: To measure suprathreshold olfactory function by using the University of Pennsylvania Smell Identification Test (UPSIT), assessing its usefulness for routine clinical use. METHODS: Forty PTC patients underwent USPIT olfactory testing. RESULTS: Twenty-nine out of 40 (73%) PTC patients (36 women, 4 men; mean age 34 years) had reduced suprathreshold smell sensation according to UPSIT scores: 19 (47%) had mild microsmia, 9 (23%) had moderate microsmia, and one (3%) was classified as having severe microsmia...

BACKGROUND: Hepatic inflammatory pseudotumor (HIP) related to IgG4 is a poorly understood entity. It is a rare finding that can simulate malignant liver tumors. Pathogenesis has been associated with pathological inflammatory response. Corticosteroids are considered standard of care once a firm diagnosis has been established. CASE REPORT: We report a case of a 60-year-old man with chronic pancreatitis who was admitted to our hospital with suspicious liver tumor. Imaging studies were inconclusive...

The aim of this study was to report on 2 patients in whom metal-on-metal (MOM) facet replacements failed, with subsequent positive findings on allergy testing. Motion-preserving devices have been used with limited success when instrumentation is indicated in the mobile spine. MOM-bearing surfaces in orthopedics were developed to increase implant longevity, yet have been associated with numerous adverse outcomes, including local tissue reactions, pseudotumors, metallosis, and the need for revision surgery. Five patients with spinal stenosis and low-grade spondylolisthesis were randomized to undergo facet replacement surgery with the ACADIA facet replacement system at the authors' institution...

Orbital swelling comprises wide spectrum of pseudotumors, benign and malignant tumor. Malignant tumor may be primary or secondary tumor, and they constitute about 36% of orbital tumors in adult. Fluorodeoxyglucose-positron emission tomography/computed tomography (FDG-PET/CT) scan is extensively used in hematological malignancies and in solid tumors for staging, treatment response, and restaging. Recently, the use of FDG-PET/CT in orbital malignancies has gained importance. The aim of this pictorial essay is to illustrate few important orbital malignancies detected in F-18 FDG-PET/CT and discuss its role in assessing the primary lesion and associated systemic finding...

INTRODUCTION: The pseudotumorous form of tuberculosis is a rare entity. Whatever its location, it can simulate neoplasia by its radiological and/or endoscopic appearances. We highlight the diagnostic difficulties associated with this type of presentation. METHODS: We performed a retrospective study of inpatient records from 2003 to 2016 in the pneumology department of La Rabta Hospital to identify cases of thoracic tuberculous pseudo-tumor. RESULTS: Seventeen patients were identified...

Hemophilic pseudotumors can occur in patients with hemophilia because of recurrent bleeding and poor hemostasis. A man in his 30s with hemophilia B and human immunodeficiency virus/hepatitis C virus co-infection complicated by liver cirrhosis presented with a large pseudotumor in the left iliopsoas muscle. However, resting to stop bleeding was difficult with his daily work. Osteolytic changes in the left ilium progressed over 8 years. A large osteolytic pseudotumor in the pelvis was also incidentally identified in his younger brother during his 30s...

Metal-on-metal (MoM) total hip arthroplasty (THA) can be associated with adverse metal reactions, including pseudotumors. This case report describes a 58-year-old female with an MoM THA-related pseudotumor that caused unilateral leg edema from compression of her external iliac vein. After thorough preoperative workup to rule out infection and deep vein thrombosis and consultation with a vascular surgeon, the patient underwent revision THA and excision of her pseudotumor. She had complete resolution of her swelling at 4 years after surgery...

PURPOSE: Retro-odontoid pseudotumor is common in elderly people and is a cause of cervical myelopathy. The goal of the study was to investigate surgical procedures, outcomes, and post-operative spontaneous regression of posterior cervical retro-odontoid pseudotumors. METHODS: The subjects were 29 patients who underwent surgery for myelopathy due to a retro-odontoid pseudotumor around the craniocervical region at 9 facilities and were followed-up for an average of 54 months (range 12-96 months)...

Intracranial hypertension is a rare entity in prepubertal children, and its differential diagnosis includes a number of systemic diseases, drugs, vitamin deficiencies and excesses, and hereditary conditions. Infectious aetiology is rare. The case of a 9-year-old boy with intracranial hypertension secondary to acute neuroborreliosis is described. He presented with daily pulsatile frontotemporal headache, pallor, photophobia and phonophobia. His neurological examination revealed papilledema with no nuchal rigidity...

A paratesticular fibrous pseudotumor is a relatively rare benign disease. Preoperatively diagnosing a fibrous pseudotumor is challenging because distinguishing these masses from malignant tumors on the basis of clinical and radiological findings can be difficult. We present a case of a 28-year-old man who presented with a painless palpable mass in the right scrotum; the fibrous pseudotumor of the tunica vaginalis was treated with organ-sparing surgery. Computed tomography and magnetic resonance imaging revealed paratesticular tumors...

Calcified Amorphous Tumors (CAT) of the heart are rare, non-neoplastic, intracavitary lesions, previously thought of as pseudotumors, hamartomas or calcified thrombi, only reported in few adults in the available literature (1). We report a case of a pedunculated oscillating CAT arising from left atrial appendage (LAA), prolapsing through the mitral valve, causing severe mitral regurgitation in a newborn. This is the only case of cardiac CAT described in a neonate.

Pulmonary inflammatory myofibroblastic tumor (IMT) is a rare mesenchymal tumor, and is considered an inflammatory pseudotumor. Here, we report of a 37-year-old woman with severe cough and stridor who was diagnosed with primary IMT of the lungs, with adenocarcinoma in situ based on the pathology in December 2012. A year later, transabdominal ultrasonography demonstrated a solid mass in the uterine wall that was initially diagnosed as a leiomyoma. However, postoperative histological examination and immunohistochemical staining revealed it as a uterine metastasis of the lung IMT...
