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...

BACKGROUND: The treatment of symptomatic partial rotator cuff tear has presented substantial challenge to orthopaedic surgeons as it can vary from conservative to surgical repair. Researches have established the influence of platelet rich plasma in healing damaged tissue. Currently very few data are available regarding the evidence of clinical and radiological outcome of partial rotator cuff tear treated with ultrasound guided platelet rich plasma injection in English literature. MATERIALS AND METHODS: 20 patients with symptomatic partial rotator cuff tears were treated with ultrasound guided platelet rich plasma injection...

The presence of simultaneous two ectopic foci of thyroid tissue (dual ectopic thyroid) is rare, and few cases have been reported in the literature. The ectopic thyroid tissue is an extremely uncommon embryological aberration due to the alterations occurring during the embryological development with incomplete migration of thyroid precursors. Commonly ectopic thyroid tissue is a midline structures, but the lateral location is possible but very rare. Ectopic thyroid is common in women and can vary in size from a microscopic focus to a few centimeters...

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. The 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 unreported complication of inappropriately deployed pCONus device.

Enlargement of the mandibular canal is a rare radiological finding. Clinically, it may or may not be associated with sensory deficits. We report four cases of widening of the mandibular canal observed with various methods of imaging with different clinical characteristics. We describe this unique radiological finding and elaborate the importance of quality assessment of the imaging that is vital for accurate diagnosis and treatment planning. Clinicians should be mindful when assessing the imaging whenever the size of the mandibular canal is implicated...

We report two cases of uterine lipoleiomyoma in postmenopausal women of ages 52 and 55 years, who presented with complaints of leukorrhea and lower abdominal pain, respectively. Lipoleiomyoma is a rare benign variant of leiomyoma, having an incidence of 0.03%-0.2%. These are benign pelvic tumors which are usually asymptomatic and commonly occur in obese postmenopausal women. However, they can occasionally present with typical leiomyoma symptoms. Imaging plays a crucial role in the diagnosis of benign pelvic tumors...

Ewing sarcoma, including classical Ewing sarcoma of the bone and primitive neuroectodermal tumors arising in bone or extraosseous primary sites, is a highly aggressive childhood neoplasm. We present two cases of Ewing sarcoma arising from the vagina in young girls. Previously reported cases in literature focused on their pathologic rather than radiographic features. We describe the spectrum of multimodality imaging appearances of Ewing sarcoma at this unusual primary site. Awareness of vaginal Ewing tumors may facilitate prompt diagnosis and lead to a different surgical approach than the more commonly encountered vaginal rhabdomyosarcoma...

Urinary bladder carcinoma (UBC) is the ninth most common malignancy and the second most common urological malignancy after prostate cancer in men. Thoracic metastases occur in more than half of those with muscle-invasive disease, and these generally assume the form of multiple solid parenchymal lesions characteristic of hematogenous seeding of the lung. Unusual patterns of thoracic spread of UBC have also been described albeit sporadically in the form of case reports and series. The aim of our case series is to provide illustrations of several atypical patterns of thoracic involvement by UBC such as isolated mediastinal lymphadenopathy, cavitary lung metastases, malignant pleural effusion, endobronchial disease, and pulmonary tumor embolism...

Renal angiomyolipomas (AMLs) and pulmonary lymphangioleiomyomatosis (LAM) are the most common tumors of the perivascular epithelioid cell (PEComa) family. Both may be associated with tuberous sclerosis (TS) complex. Epithelioid AML (EAML) is a rare variety of AMLs, with a potential aggressive behavior. There are few reports in the English literature addressing on the imaging findings of renal EAMLs, which are considered nonspecific. We present the sonographic, computed tomographic, and magnetic resonance imaging findings of a renal EAML in a pregnant woman with concomitant pulmonary lesions indicative of LAM, without stigmata of TS...
