It is important to differentiate low grade malignant peripheral nerve sheath tumors (MPNSTs) from benign nerve sheath tumors as MPNSTs may require a more aggressive treatment strategy during and after initial resection. Loss of expression of the trimethyl Histone H3 at the Lys27 position (H3K27-me3) has recently been described in MPNSTs, and may help distinguish this tumor from pathologic mimics. A 43-year-old woman presented with symptoms of radiculopathy and a history of pelvic radiation for cervical cancer 7 years prior...

Pancreatic hamartoma is a rare benign malformation that resembles a neoplasm and may be mistaken for a malignancy. The imaging findings of pancreatic hamartoma are not well established, as only one radiological case report has been described since 1983. Herein, we discussed a case of pancreatic hamartoma in a 35-year-old woman and conducted a literature review focused on imaging findings and differential diagnosis of pancreatic hamartoma. Increased late enhancement on post-contrast dynamic study and absence of diffusion restriction may be characteristic MR imaging findings of pancreatic hamartoma that may narrow the differential diagnosis of hypervascular pancreatic lesions...

Primary central nervous system melanoma is rare, accounting for approximately 1% of total melanoma cases (1-3). Primary central nervous system melanoma localized to the spinal cord is even rarer. The cervical and thoracic levels are most frequently involved. There are no pathognomonic imaging characteristics and diagnosis must be confirmed immunohistologically. The preferred treatment is gross total resection. Utilization of adjuvant radiotherapy and chemotherapy may improve disease-free survival. The prognosis for primary central nervous system melanoma is generally better than that of metastatic and cutaneous melanoma, although there are relatively few cases from which to draw conclusions...

Primitive neuroectodermal tumor is a high-grade malignant tumor originating from the neural crest and neuroectoderm, which can be subdivided into central and peripheral categories. Peripheral primitive neuroectodermal tumor is thought to be identical to Ewing's sarcoma, and falls under a broader category of Ewing's sarcoma family of tumors. Very rarely, it may present without osseous involvement, known as extraosseous Ewing's sarcoma. Here we present a case of a 38-year-old woman, who presented with several-month history of a slow-growing chest wall mass, initially thought to be a breast mass...

We report a rare case of giant angioleiomyoma located in the uterus and detected in a 37-year-old woman. The uterus is an extremely rare location for angioleiomyoma. The definitive diagnosis is usually obtained only after the histopathologic examination because the imaging criteria are challenging for this disease. We focused our attention on the main computed tomography features able to provide a robust preoperative diagnosis of this rare clinical entity.

BACKGROUND Epidural venous plexus (EVP) engorgement occurs due to many conditions, so it can be easily misdiagnosed. This becomes problematic when the diagnosis requires prompt treatment for a good outcome, especially when it results in cauda equina syndrome (CES). We report a case of extensive iliocaval thrombosis leading to epidural venous plexus and ascending lumbar vein engorgement as an outcome of deep venous thrombosis (DVT) due to probable adverse effects of oral combined contraceptive pills (OCCP). CASE REPORT A 42-year-old woman presented to a rural medical facility with bilateral lower-limb swelling and skin darkening for 2 days...

RATIONALE: Paraneoplastic cerebellar degeneration (PCD) is an immune-mediated neurological deficit affecting the cerebellum. Anti-Yo antibody positive PCD is a rare occurrence most likely associated with gynecologic or breast malignancies. The identification of the underlying tumor is a diagnostic challenge in many of these patients. PATIENT CONCERNS: We present a 68-year-old woman with acute symptoms of PCD as a first sign of underlying occult malignancy. Further investigation revealed a positive anti-Yo antibody...

Inflammatory myofibroblastic tumors (IMTs) are neoplasms with low malignant potential, and the most common tumor in the lung and orbit. Their occurrence in the uterus is rare. Approximately 50% of IMT patients have anaplastic lymphoma kinase gene ( ALK) rearrangements. Recent studies described novel fusions involving ROS1, platelet-derived growth factor receptor beta ( PDGFR-β), and ETS translocation variant ( ETV6) genes in a subset of ALK-negative patients. We report a 44-year-old woman with anemia and uterine IMT...

Biliary cystic disease is a rare entity. Twenty-five per cent of cases are diagnosed during adulthood and only a few reports have described this condition during pregnancy, where it represents a therapeutic challenge for both obstetricians and surgeons with regard to the risks it entails for the patient and the fetus.Definitive management is surgical resection, as cysts may progress to malignancy if untreated. During pregnancy, resection is generally deferred to after delivery, especially in the context of suspected cholangitis...

Schwannomas are tumours that arise from Schwann cells of the peripheral nerve sheath and rarely occur in the retroperitoneum. We report a 45-year-old woman who presented with a 2-year history of continuous progressive right-sided lower back and dull flank pain radiating into her posterolateral thigh. Abdominal magnetic resonance imaging showed a homogenous soft-tissue tumour with thick capsular lining, which lay in the right retroperitoneum. The tumour was removed at surgery. A histological examination confirmed the diagnosis of benign encapsulated cellular schwannoma...

Intraductal papillary neoplasm of the bile duct (IPNB) is a rare variant of bile duct tumors characterized by papillary growth within the bile duct lumen and recognized precursor of invasive carcinoma. IPNB was detected incidentally in a 60-year-old woman during check up. Radiologic images revealed a huge cystic mass with papillary projection and markedly dilated bile ducts. Biopsies revealed high-grade IPNB. Cholangioscopy detected a connection between the right posterior bile duct and cyst lumen with epithelial dysplasia of the bile duct...

The causes of osteolytic lesions found in radiological examinations are not quite certain. Therefore, to determine the appropriate treatment method, various approaches and analyzes are required to find the real cause. Hyperparathyroidism is one of the diseases which forms osteolytic bone lesions so-called brown tumor. A 55-year-old woman who had painful osteolytic bone lesions in both hip joint areas was diagnosed as parathyroid carcinoma after serial work-up. She underwent parathyroidectomy and follow-up imaging showed a decrease in brown tumor size and bone consolidation in the subchondral bone destruction area...

Introduction: Campylobacter is a common pathogen of the gastrointestinal tract, but invasive disease is rare. Campylobacter fetus can play a role in osteomyelitis, meningitis and joint infection and has a prediliction for the vascular endothelium, causing mycotic aneurysms, thrombophlebitis and endocarditis. Here we present a case of prosthetic valve endocarditis caused by C. fetus and a review of the literature. Case presentation: An 85-year-old woman with a tissue aortic valve replacement and atrial fibrillation was admitted to hospital with tonic-clonic seizures, right-sided hemiparesis, facial droop and hemianopia...

Intraosseous lipomas occurring in the bones of the upper limbs are very rare. The tumor often occurs in long bones, especially the calcaneus. Usually patients with intraosseous lipomas present with mild clinical features. Thus far, bone destruction caused by the tumor has not been reported. The present study reported a case of an aggressive intraosseous lipoma that developed in the intermediate phalanges of the thumb. This is an extremely rare case with extraosseous development, which occurred at a rare site...

Carcinoembryonic antigen (CEA) is still the most widely used tumour marker for gastrointestinal cancer. CEA was originally thought to be a specific marker for colorectal cancer, but it turned out to be a non-specific marker for further studies. CEA levels can be elevated in breast, lung and liver cancers, among others, including medullary thyroid cancer. The authors report a case of a 73-year-old woman who had a right hemicolectomy for an ascending colon adenocarcinoma and showed a persistent elevation in the CEA marker during follow-up...

BACKGROUND: The management of metastatic Renal Cell Carcinoma (RCC) has changed dramatically in the last 20 years, and the role of surgery in the immunotherapy's era is under debate. Metastatic lesions interesting pancreas are infrequent, but those harbouring from RCC have an high incidence. If metachronous resections are not rare, synchronous resection of primary RCC and its pancreatic metastasis is uncommonly reported, and accounts for a bad prognosis. CASE PRESENTATION: We report the case of a 68 years old woman, who presented hematuria at hospital incoming, with radiological appearance of a 13 cm left renal mass, with a 2...

Tracheobronchial calcifications are common in adults and considered as a physiological process of aging with no clinical significance in otherwise asymptomatic, healthy individuals. We are presenting a case of tracheobronchial tree calcifications as detected on F-NaF PET/CT in a 75-year-old woman. Many previous publications have reported the accumulation of NaF in extraosseous organs; these observations further set new directions in the evaluation of the metabolic activity of macrocalcification and microcalcification using molecular imaging probes...

A 76-year-old woman was referred to our hospital due to massive gingival bleeding following teeth extraction. Laboratory findings suggested disseminated intravascular coagulopathy (DIC). Enhanced computed tomography and magnetic resonance imaging disclosed multiple hypervascular liver masses of 2-6 cm in diameter, the largest of which displaying an irregular enhancement pattern. We considered that her DIC was caused by the multiple liver masses and commenced repeated erythrocyte/fresh frozen plasma infusión and gabexate mesilate administration...

BACKGROUND: Safe excision of spinal cord tumors depends on sufficient visualization of the tumor and surrounding structures. In patients with spinal cord tumor adjacent to a stenotic spinal canal, extensive bony decompression proximal and distal to the tumor should be considered for safer excision of the tumor. Extensive wide laminectomy is one choice for such cases, but postoperative problems such as kyphotic deformity remain a concern. CASE PRESENTATION: A 76-year-old man and a 60-year-old woman presented with symptomatic intradural extramedullary spinal cord tumors in the cervical spine...
