Anatomical study of hypospadias penis using magnetic resonance imaging in children.

INTRODUCTION: To assess the various anatomical patterns of the hypospadias penis, anatomical and histological study of the penile tissues, planes, and vascular patterns, and imagings such as ultrasound of penis, elastography, and Magnetic resonance imaging (MRI) of penis have been described in the literature. All these have been done to attempt the identification of anatomical variations that may influence surgical outcomes. There are very limited MRI studies of hypospadias penis to look for the pristine anatomy. OBJECTIVE: The objective was to identify anatomical variations in hypospadias penis such as the penile tissues and planes and the vascularity using MRI. MATERIAL AND METHODS: The total number of patients enrolled was 24 from January 2019 to July 2020. This included all the cases of hypospadias at any location aged ≥5 years. MRI penis was done using 3T (3 Tesla) MRI scanner (GE Healthcare signa 3T Scanner machine) with 3 mm body coil slice thickness and the surface coil of 3 inches. Non-contrast images were taken using fast spin-echo sequences in sagittal, coronal, and transverse planes. The findings analyzed were: presence and distribution of penile tissue and fascial structures, urethral plate thickness, and penile vasculature. RESULTS: The mean age was 7.62 ± 2.14 years. The types of hypospadias included were Coronal 1/24 (4.2%), Subcoronal 14/24 (58.3%), Distal penile 3/24 (12.5%), Midpenile 5/24 (20.8%) and Penoscrotal 1/24 (4.2%) (Summary Table 1). The mean urethral plate thickness was 1.33 ± 0.38 mm. The penile soft tissues were well visualized along with their fascial planes. The majority of patients (91.7%, 22/24) had Superficial Dartos vessels with both branches. Bulbourethral vessel was present in 18 (75.0%) cases but could not be visualized in the rest. Ventral and Lateral Dartos vessels were seen in 20 (83.3%) cases. Perforators distal to meatus were visualized in 21 (87.5%) cases and not visualized in 3 (1 each in Penoscrotal, Midpenile, and Coronal hypospadias). Collaterals at corona sulcus were visualized in 23 (95.8%) cases, at paraurethral spongiosum in 15 (62.5%) cases, and at dorsum in 22 (91.7%) cases. CONCLUSION: 3T MRI gives precise images in hypospadias with relation to the tissue and fascial planes of the penis. The vascular pattern visualization in these patients may be confirmed by the availability of a dedicated penile coil which will help to improve the resolution of the penile structures. Analyzing the penile vascular pattern and correlating it with surgical outcomes may aid the surgeon's knowledge of hypospadias, develop new surgical techniques and hence reduce complications.

Surgical Occlusion of Leaking Bronchus by a Serratus Anterior Flap in a Child with Langerhans Cell Histiocytosis.

Langerhans cell histiocytosis is an uncommon disease of childhood. Intrathoracic transposition flaps have been described for a management of number of conditions. We discuss our experience of the use of serratus anterior flap for the obliteration of a pulmonary bulla with a communicating airway, in a 1½-year-old pediatric patient with multisystem Langerhans cell histiocytosis who presented with recurrent pneumothorax with empyema due to rupture of bullae.

Congenital lateral facial teratoma: A case report and review of literature.

Facial teratomas are uncommon tumours in children that distort the face and may be associated with functional problems. They are less common than cervical teratomas though they are often grouped together and considered an emergency due to their tendency to cause respiratory compromise. They tend to be large and cause cosmetic issues; hence usually noticed early and medical help sought promptly by parents. The close proximity of facial teratomas to structures like eyes, parotid gland, facial nerve, vessels and brain makes them challenging and requires a patient and meticulous exploration during surgery. We present a case of an 11 month old girl with left sided temporal teratoma. Well planning of the incision and complete excision of the tumour with careful sparing of the facial nerves and parotid gland yielded good result.

A novel technique of abdominoplasty for prune belly syndrome.

Prune belly syndrome is an extremely rare congenital condition occurring predominantly in males. This triad syndrome comprises of partial or complete deficient abdominal wall muscles, undescended testes and dilated urinary collecting system. We present the case of a 2-year-old male patient, who presented with classic prune belly syndrome, operated with modification in classical Monfort technique of abdominoplasty. The basis of this approach was to save and use the supraumbilical abdominal wall which has better tensile strength. The infraumbilical skin was mostly discarded. The outcome was better in terms of cosmetic appearance as the scar was limited to the lower abdomen and better anterior abdominal wall strength.

Large falciform ligament cyst in a child: A rare entity of peritoneal cysts and review of the literature.

Peritoneal cysts are not uncommon in children - mesenteric/omental cysts being the commoner entity. Peritoneal cysts in the falciform ligament are a very rare entity reported in the literature. We present a 5-year-old boy who presented with pain upper central abdomen and few episodes of non-bilious vomiting for 1 year. He was stable on examination, with abdominal examination revealing the fullness of the abdomen with palpable generalised cystic mass which was mobile transversely. Ultrasound and contrast-enhanced computed tomography of the abdomen revealed intra-peritoneal cystic lesion measuring 13 cm × 11.5 cm × 9 cm with septations seen in the abdominal cavity from the epigastric region to the infraumbilical region (D11-L5 level). Laparoscopy showed a large cyst of the abdomen arising from the anterior abdominal wall, along the falciform ligament. The dark yellow fluid was aspirated and the cyst was excised leaving a part which was adherent to the anterior wall. Histopathology revealed cuboidal epithelium lined by the fibrous wall. The patient is doing well at 6 months follow-up. Falciform ligament cysts are very rare and laparoscopy can confirm the diagnosis as well as help in excision of the cyst with good results.

Retained wooden foreign body in groin in a child: A case report and review of literature.

Wooden foreign body (WFB) injuries in children are common. They may report with acute presentation or be delayed as retained foreign body giving rise to complications. Cases with superficial skin penetration by these foreign bodies and acute presentation may be convenient to diagnose and remove. However, localising deeply impacted and chronically retained WFB is challenging, as they are usually not radiopaque and have a tendency to move deeper into the surrounding soft tissues with time. Foreign body retained for prolonged duration may present with either cellulitis, deep tissue infections, sinus, restriction of joint movements, necrotising fasciitis, osteomyelitis or tumour-like mass. We present an 8-year-old boy with discharging sinuses in the right iliac fossa and medial aspect of the right upper thigh, due to an impacted WFB for 3 months. Prompt radiological imaging and surgical removal helped him recover completely.
