Appendiceal Diverticulitis Mimics Cecal Diverticulitis Diagnosed Preoperatively.

Appendiceal diverticulitis is an uncommon condition that clinically resembles acute appendicitis. However, it is an incidental finding in histopathological studies and is rarely diagnosed preoperatively by imaging studies. In this article, we present the clinical and imaging findings of a male patient presenting with right upper quadrant pain with a preoperative imaging diagnosis of appendiceal diverticulitis.

Review of diagnosis, differential diagnosis, and management of retroperitoneal lymphangioma.

Lymphatic malformation (LM) is the currently preferred term for what was previously known as lymphangioma. Retroperitoneal LMs are extremely rare, benign, cystic masses that arise from lymphatic vessels. They can be challenging to diagnose because they resemble other retroperitoneal cystic tumors.

Pituitary Apoplexy and Subdural Hematoma after Caesarean Section.

Pituitary apoplexy can occur postpartum, and subdural hematoma following epidural anesthesia is a rare complication. Cooccurrence of these two complications is extremely rare and has not been previously reported in the literature. In this article, we present a case of pituitary apoplexy along with intracranial subdural hematoma happening two days after spinal anesthesia for cesarean section.

Pelvic schwannoma in an adult male.

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.

Traumatic Kidney in a Patient With Unilateral Renal Cystic Disease.

Renal trauma occurring in patients with unilateral renal cystic disease (URCD) is extremely rare. Unilateral renal cystic disease is benign, nonprogressive, nonfamilial, nonencapsulated, and unrelated to cysts in other organs. It should be differentiated from autosomal dominant polycystic kidney disease (ADPKD) parenthesis, multicystic dysplastic kidney disease, multiple renal simple cysts, and cystic renal neoplasms.

Balo's Concentric Sclerosis Mimicking Tumor on Magnetic Resonance Imaging in a Young Patient.

Balo's concentric sclerosis (BCS) is a rare demyelinating disease known as Multiple Sclerosis (MS) lesion type III. It is a disease of the white matter of the brain characterized by a round lesion with variable concentric myelinated and demyelinated layers, appearing as "onion bulb." We present a case of BCS and discuss the imaging findings and management strategies of this disease.

Diffuse Pancreatic Carcinoma with Hepatic Metastases.

Pancreatic cancer is one of the seven leading causes of cancer death worldwide. Diffuse pancreatic carcinoma is very rare and underreported in the literature. Many advances have been made in the diagnosis and management of pancreatic cancer.
