Segmental testicular infarction (STI) is a rare cause of acute scrotum. The spectrum of findings on gray-scale and color Doppler ultrasonography differ depending on the time between the onset of testicular pain and the ultrasonography examination. We are not aware of the usefulness of shear-wave elastography for the diagnosis of STI. We report the shear-wave elastography features in a case of STI and discuss the role of this diagnostic modality in the differential diagnosis.

Giant multilocular prostatic cystadenoma is a rare benign tumor that evolves from the prostate gland. Obstructive voiding symptoms occur in all reported cases. These lesions do not invade adjacent structures. Preoperative radiologic evaluation can define the benign nature of the lesion. Here we report a case of large cystic lesions identified by magnetic resonance imaging and sonographic findings that caused an extensive mass effect in the pelvis. When retrovesical, huge cystic lesions fill the pelvis completely in young men, with high levels of serum prostate-specific antigen, giant multilocular prostatic cystadenoma should be considered as a differential diagnosis. To our knowledge, this is the youngest case of prostatic cystadenoma reported in the literature.

Neurofibromatosis type 1 disease is characterized by pigmented cutaneous lesions and generalized tumors of a neural crest origin and it may affect all the systems of the human body. Sphenoid dysplasia is one of the characteristics of this syndrome and it occurs in 5-10% of the cases; further, abnormalities of the sphenoid wings are often considered pathognomonic. However, complete agenesis of a sphenoid wing is very rare. We report here on an unusual case of neurofibromatosis type 1 disease with the associated absence of a sphenoid wing that was diagnosed by using multidetector computed tomography.

A patient with a 2-year history of pain in the left arm, and decreased strengths unrelieved by non-steroidal anti-inflammatory therapy, was being referred for repeating radiography. The radiologic examinations have demonstrated a unique pattern of non-contiguous osteolysis in the left elbow, proximal and distal radius, ulna, wrist, carpal bones, proximal and distal metacarpals and phalanges. Multi-site biopsies were being performed and confirmed the diagnosis of massive osteolysis. To our knowledge, this is the first case in which multifocal, non-contiguous osteolysis with skip lesions without associated nephropathy and without a hereditary pattern is being described in one extremity.
