A case of perirenal extra-adrenal myelolipoma mimicking liposarcoma.

Myelolipoma is a benign tumor composed of mature adipose tissue and normal hematopoietic components. It usually occurs in the adrenal glands but rarely in the extra-adrenal region. However, it is difficult to differentiate extra-adrenal myelolipoma from well-differentiated liposarcoma on the basis of the radiological findings.

[A Case of Secondary Syphilis Mimicking a Penile Cancer with Lymph Node Metastases].

A 42-year-oldman visited our hospital because of gradually worsening penile swelling over 3 weeks. A hard mass on the glans was palpated; however, we were unable to observe it due to severe phimosis. Magnetic resonance imaging of the pelvis revealed enlargement of glans and swelling of bilateral inguinal lymph nodes as both showed a low signal intensity on T2-weightedimaging, a high signal intensity on diffusion-weighted imaging, and a low signal intensity on the apparent diffusion coefficient map.

A case of testicular torsion successfully treated with tunica albuginea incision and tunica vaginalis patch.

Previous studies indicated the occurrence of compartment syndrome after testicular detorsion. In such cases, testicular blood flow may improve with tunica albuginea incision. A 14-year-old man presented with right-sided testicular torsion.

Apparent Diffusion Coefficient Map-Based Texture Analysis for the Differentiation of Chromophobe Renal Cell Carcinoma from Renal Oncocytoma.

Preoperative imaging differentiation between ChRCC and RO is difficult with conventional subjective evaluation, and the development of quantitative analysis is a clinical challenge. Forty-nine patients underwent partial or radical nephrectomy preceded by MRI and followed by pathological diagnosis with ChRCC or RO (ChRCC: n = 41, RO: n = 8). The whole-lesion volume of interest was set on apparent diffusion coefficient (ADC) maps of 1.
