Piriformis syndrome is an uncommon condition that causes significant pain in the posterior lower buttocks and leg due to entrapment of the sciatic nerve at the level of the piriformis muscle. In the typical anatomical presentation, the sciatic nerve exits directly ventral and inferior to the piriformis muscle and continues down the posterior leg. Several causes that have been linked to this condition include trauma, differences in leg length, hip arthroplasty, inflammation, neoplastic mass effect, and anatomic variations...

Segmental neurofibromatosis type 5 (NF5) is a rare form of NF, in which the cutaneous and/or neural changes are confined to one region of the body. It is often underdiagnosed or undetected due to the absence of symptoms. Inheritance of NF is different from other types of NF. Intraosseous neurofibromas are rare tumors which develop from nerves supplying the periosteum or nerves following the intraosseous course. Plexiform neurofibroma with associated intraosseous neurofibroma is extremely rare. We report a case of plexiform neurofibroma in the left axilla of a 17-year-old female with associated intraosseous neurofibroma in adjoining left humerus...

Background: Brain tumor is one of the most common tumors. A successful treatment might be achieved with an early identification. Pathological investigation as the gold standard method for tumor identification has some limitations. Noninvasive assessment of tumor specifications may be possible using perfusion-weighted magnetic resonance imaging (MRI). Cerebral blood volume (CBV) and cerebral blood flow (CBF) could be calculated based on dynamic contrast-enhanced MRI (DCE-MRI) in addition to dynamic susceptibility contrast MRI (DSC-MRI) modality...

Determining the presence and characteristics of vascular flow is an essential part of sonography interrogation. However, small vessels and low velocities are not always possible to depict with conventional color and power Doppler ultrasound. This can be frustrating, especially when the diagnosis depends mainly on the existence of vascular flow, the sonographic examination will be inconclusive, further imaging examinations will be required and diagnosis delayed. Superb microvascular imaging (SMI) is a novel vascular imaging mode, which provides visualization of low velocity and microvascular flow...

pCONus is a stent like endovascular device which aids in retention of coils within wide necked bifurcation aneurysms. It is retrievable even after complete deployment and is detached electrolytically. pCONus aided coiling of wide necked bifurcation aneurysms has a high technical success rate and a good safety profile. Different complications have been described in literature with the usage of pCONus. This case report describes a yet unreported complication of un-re-sheath-ability of a misaligned deployed pCONus device...

Arteriovenous malformations (AVM) of the inferior mesenteric artery are rare. They may be primary (congenital or idiopathic) or secondary (acquired) after trauma or of iatrogenic origin. Of the abdominal AVM, the inferior mesenteric trunk is the least commonly involved. Most reported cases are of iatrogenic origin, resulting from colon surgery. Only 17 cases have been described and published in the literature. The objective of this work is to make known a case treated in our center. We present a case of 73-year old male, who came to the emergency service with symptoms of abdominal distension, pain lasting 48 hours along with months of diarrhoea...

Snapping pes anserinus syndrome is an often encountered cause of medial knee snapping. It results from impingement and translation of the gracilis tendon or semitendinosus tendon over the osseous structures of the knee during active flexion and extension. Ultrasonography is often the diagnostic imaging test of choice in cases of mechanical snapping. We report 2 cases of painful snapping pes anserinus and highlight the value of dynamic ultrasound in making an accurate diagnosis so as to direct care.

Schwannomas are benign soft-tissue tumors that arise from peripheral nerve sheaths throughout the body and are commonly encountered in patients with neurofibromatosis Type 2. The vast majority of schwannomas are benign, with rare cases of malignant transformation reported. In this pictorial review, we discuss the magnetic resonance imaging (MRI) appearance of schwannomas by demonstrating a collection of tumors from different parts of the body that exhibit similar MRI characteristics. We review strategies to distinguish schwannomas from malignant soft-tissue tumors while exploring the anatomic and histologic origins of these tumors to discuss how this correlates with their imaging findings...

Many children frequently fail extubation or require a prolonged period of positive pressure ventilation support after cardiac surgery. Pediatric cardiac Intensive Care Unit (PCICU) ultrasound (US) stands as a simple, basic bedside tool that can be performed by trained intensivists for the diagnosis with immediate implication on therapeutic decisions in multiple scenarios that physicians may face in PCICU. Bedside US is widely available, convenient, and inexpensive. This educational article based mainly on our own experience is highlighting the role of US in detecting the most common causes of respiratory weaning difficulties and extubation failure in postoperative cardiac children through proposed illustration and algorithm...

Primary perivascular epithelioid cell tumor (PEComa) of the liver is a very rare tumor that originates from mesenchyma. Gastrointestinal tract with perivascular distribution is the most common anatomic sites of these tumors. Only few cases of hepatic PEComa have been described so far. Malignant PEComas exhibit aggressive behavior with poor prognosis, making early diagnosis crucial. Hereby, we report a 79-year-old female with unusually located mass in the liver. A partial curative hepatectomy has been done, and PEComa was diagnosed histopathologically...

Primary pulmonary angiosarcoma is extremely rare. It is often characterized by a clinically indolent course and delayed diagnosis. To date, there have been <20 cases reported. By far, little article correlates the clinical presentation, the imaging findings with the pathology. The authors present a case of middle-aged gentleman with primary pulmonary epithelioid angiosacroma which we initially thought as tuberculosis (TB) infection. A 60-year-old gentleman, with a history of 6 months on and off blood stained sputum, was admitted for an episode of massive hemoptysis...
