Spindle cell carcinoma is a rare biphasic tumor consisting of epithelial and mesenchymal components. Presence of this tumor type in the tongue has rarely been reported. Herein, a case of 55-year-old woman who presented with a polypoid lesion at her tongue has been reported. Surgery was performed and pathologic examination revealed a spindle cell carcinoma. We present this rare tumor with an unu...

Angioleiomyoma of the scrotum is a rare benign lesion which can mimic a paratesticular tumor. Any solid mass within the scrotum is considered malignant until proven otherwise. Here, we present a case of an angioleiomyoma of the scrotum in a 33-year-old male who presented with painful scrotal mass. Scrotal ultrasonography demonstrated a solid mass in the scrotum, and surgical excision was carrie...

We report serial MR findings in a middle-aged woman with a neurenteric cyst involving the cerebellopontine angle cistern with xanthogranulomatous changes. On the initial gadolinium-enhanced T1-weighted MR images, the solid portion of the lesion had homogeneously strong enhancement. Follow-up MR images obtained 6 months later showed that the mass had increased in size; however, the solid portion...

A 54-year-old woman presented to the emergency room with 3 months of slurred speech, language problems, and right hemiparesis. Initial impression based on history, exam, and imaging was brain abscess vs. primary or metastatic neoplasm. Brain biopsy of the lesion and pathologic specimens were obtained. Below is a description of her presentation, hospital course, imaging, and pathology, as well a...

We describe a 16-year-old male with ultrasound evidence of a 1.3 cm right paratesticular nodule, which was managed by intraoperative frozen section and excisional biopsy. The pathologic findings were consistent with benign fibrous pseudotumor of the tunica vaginalis testis, which is a very rare lesion in the pediatric population. Consideration of fibrous pseudotumor in the differential diagnosi...

GCTB is the most challenging benign bone tumors. On the other hand, the natural history of this bony tumor may be different from local bony lesion to local metastasis, even malignant transformation which is rare. Symptoms are highly variable and may range from asymptomatic in some patients, joint pain in tumor near the joint and even pathologic fracture. In long-term follow op swelling or palpa...

A 63-year-old African American female with history of bilateral breast cancer status after lumpectomy and radiation therapy presented with right hand, wrist, and arm pain. She was found to have a right axillary mass and a large lesion in the right brachial plexus. A biopsy of the brachial plexus mass came back as a malignant peripheral nerve sheath tumor. This case report illustrates the critic...

The case of a rare, mature teratoma of the oculomotor nerve manifesting as an interpeduncular cistern mass is presented. A basilar tip aneurysm initially was suspected on the basis of lesion location and MR imaging appearance. Subsequent CT and catheter angiography studies were atypical for aneurysm, leading to surgical biopsy. Pathologic analysis revealed a well-circumscribed mass composed of ...

We present a case of trigeminal neuralgia with cranial normal magnetic resonance image (MRI) and computed tomography. The pain was not relieved by carbamazepine and microvascular decompression surgery was done. After two months the pain was similar to the condition before surgery. At this time, MRI showed an expansive lesion in Meckel's cave that was treated with radical resection by extra-dura...

An 8-yr-otd boy with a l-too history of culture-negative fever and anemia underwent gallium, ultrasound, and computed tomography studies as part of the evaluation of a fever of unknown origin. These studies revealed a mobile gallium-avid solid abdominal mass subsequently proven to be an inflammatory pseudotumor of the mesentery, a rare benign mass. This report documents the gallium-avid nature ...
