Background: Pediatric germ cell tumors (GCTs) are rare, heterogeneous neoplasms with peak incidence in children under 4 years of age and during adolescence. The clinical presentation and treatment outcomes of GCTs are not well-studied in developing countries. This study aimed to assess the clinicopathological patterns and treatment outcomes of pediatric GCT patients treated at the largest tertiary referral hospital in Ethiopia.

Small bowel obstruction (SBO) is a common surgical emergency, but appendico-ileal knotting is an exceptionally rare cause. This condition involves the appendix forming a constricting loop around the ileum, potentially leading to closed-loop obstruction and bowel ischemia. We report the case of a 57-year-old male from Ethiopia who presented with classical features of SBO, including abdominal pain, bilious vomiting, and failure to pass stool and flatus.

A cecal volvulus in malrotation in a postpartum patient is an infrequent clinical entity. We present a case of a 24-year-old male patient with cecal volvulus in malrotation. The patient underwent counterclockwise detorsion, division of Ladd's bands, right hemicolectomy with end ileostomy, transverse colopexy, and early ileostomy reversal.

Syringohydromyelia, syringobulbia, and syringocephaly are rare manifestations of Chiari-I malformation (CM-I), each resulting from disrupted cerebrospinal fluid dynamics. While syringomyelia is commonly associated with CM-I, the rostral extension of syrinx cavities into the brainstem (syringobulbia) and cerebral parenchyma (syringocephaly) is very rare, with limited cases reported globally. This case report describes a 40-year-old woman presenting with progressive neurological deficits, including hemiparesis, sensory disturbances, and bulbar symptoms.

Background: Lateral mass screw and rod fixation is widely used for posterior cervical arthrodesis and stabilization in cases of cervical instability, trauma, neoplasm, decompression, and deformity correction. However, clinical and radiological data on its outcomes, especially in our setting, remain limited.

Objective: Clinical and radiographic evaluation of posterior cervical arthrodesis and stabilization using lateral mass screws and rod fixation.

Misoprostol, a prostaglandin E1 analog, is widely used in obstetrics for abortion induction and labor management. Although generally safe, it can lead to rare complications such as uterine rupture, even in patients without prior uterine scarring. This case report describes a 27-year-old gravida 3, para 1 woman with no history of uterine surgery who presented with a second-trimester missed septic abortion.

Plummer-Vinson Syndrome (PVS) is a rare disorder characterized by the triad of dysphagia, iron-deficiency anemia, and esophageal webs. Limited data on its prevalence exist, with most information derived from case reports. We present the case of a 60-year-old woman with a 6-month history of a progressively enlarging anterior neck mass and worsening symptoms of heart failure, heat intolerance, and dysphagia.

Intussusception is a common cause of bowel obstruction in children, typically occurring in those under 3 years old and often idiopathic. Secondary intussusception is less common in pediatric patients and usually involves a pathological lead point. Appendiceal intussusception is rare, occurring in only 0.

Juvenile dermatomyositis (JDM) is a rare autoimmune disorder characterized by chronic inflammation of the skin and skeletal muscles, often complicated by systemic manifestations and secondary infections. This case report describes a 12-year-old boy with a history of JDM who developed pyomyositis, a rare bacterial infection of skeletal muscles, following immunosuppressive therapy with methotrexate and low-dose steroids. The patient presented with fever, swelling, and tenderness in the left leg, with imaging confirming abscess formation.

T-cell/histiocyte-rich large B-cell lymphoma (THRLBCL) is a rare and aggressive subtype of diffuse large B-cell lymphoma (DLBCL) that is uncommon in children. Here, we present the case of an 8-year-old male with a 3-month history of low-grade intermittent fever, significant weight loss, loss of appetite, and progressive abdominal swelling. Examination revealed splenomegaly and a palpable midabdominal mass, with laboratory findings showing bicytopenia.

Introduction: Appendico-ileal knotting is an extremely rare complication of acute appendicitis resulting in small bowel obstruction (SBO) and potential strangulation. It accounts for a negligible fraction of SBO cases, with only a handful of cases reported globally in the literature. The condition arises when an inflamed or gangrenous appendix forms a knot around the ileum, often exacerbated by adhesions or anatomical variations, leading to closed-loop obstruction and, if untreated, bowel strangulation and gangrene.

Spinal schistosomiasis, a rare manifestation of schistosomal infection, can closely mimic the presentation of spinal cord tumors and pose significant diagnostic challenges. We present the case of a 12-year-old boy from northern Ethiopia who experienced progressive back pain, tingling sensations in his lower extremities, and intermittent fever. Initially referred with a presumptive diagnosis of myxopapillary ependymoma for pediatric hematology-oncology evaluation, his marked eosinophilia and history of swimming in local rivers raised suspicion for spinal schistosomiasis.
