Left-sided appendicitis is usually caused by situs inversus totalis or midgut malrotation. Clinical and imaging diagnoses have been presented relatively fully in the literature. However, this is a rare condition, and each related case should be further reported to help the day-to-day clinician better investigate and understand. Therefore, in this paper, we present a case of left-sided acute appendicitis in an adult male patient with situs inversus totalis. In addition, we also discuss the laparoscopic technique of the left-sided appendectomy as it is technically more difficult because of the mirror nature of the anatomy.
Schwannomas are benign nerve sheath tumors that are generally encapsulated and commonly detected in the head, neck, and mediastinal regions. Schwannomas localizing in the pelvis are extremely rare and tend to be asymptomatic initially due to slow growth rate. Schwannomas may be misdiagnosed as urologic or gynecologic tumors. Pelvic schwannomas are typically solitary, large, and well-circumscribed masses in the retroperitoneum or presacral areas. Other imaging characteristics are cystic degeneration, repeated hemorrhages, and calcifications. Calcification patterns can be punctate, speckled, curvilinear, or along the walls of the masses. We report a young man with a pelvic schwannoma with typical imaging features.
